Why Military and Tactical Boots Require Advanced Footwear Testing?

When it comes to mission-critical environments, no piece of gear is more essential than a reliable pair of military or tactical boots. These boots are subjected to some of the most demanding conditions imaginable—from extreme temperatures and rugged terrains to long hours of wear and exposure to water, chemicals, and impact. Ensuring these boots perform consistently under such stress is not just a matter of comfort—it's a matter of survival and mission success. This is where a Footwear Testing Lab plays an indispensable role.

In this blog, we’ll explore why military and tactical boots require advanced footwear testing, the types of tests performed, and how a certified footwear testing lab ensures compliance, safety, and durability in extreme conditions.

The Critical Role of Tactical Footwear

Military personnel, first responders, law enforcement officers, and tactical teams rely on boots that must:

Provide optimal ankle support and shock absorption

Withstand wear-and-tear in rugged terrains

Resist water, oil, chemicals, and extreme temperatures

Maintain traction in both dry and wet environments

Remain functional over long, physically demanding missions

Given these requirements, military boots cannot be tested like ordinary footwear. They need rigorous performance testing—something only an advanced Footwear Testing Lab can provide.

Why Advanced Testing is Essential

Here’s why tactical footwear demands more than just basic quality control:

1. User Safety

Tactical boots are worn in high-risk environments. A sole that slips, a seam that tears, or insulation that fails can lead to serious injury. Advanced testing ensures boots deliver the protection users expect.

2. Extreme Usage Scenarios

Unlike everyday shoes, tactical boots may be worn for 12–16 hours a day across various climates, terrains, and situations—including combat. They must endure prolonged stress, friction, and environmental hazards.

3. Compliance with Military Standards

Military gear must comply with strict national and international defense standards (e.g., MIL-SPEC, NATO standards). These require high-precision testing that only a specialized Footwear Testing Lab can perform.

Key Tests Performed on Military and Tactical Boots

Footwear testing labs perform a wide range of tests—mechanical, environmental, and chemical—to ensure tactical boots meet or exceed expectations.

1. Abrasion Resistance

Boots are tested for sole and upper material durability using abrasion machines that simulate sand, rocks, and rugged terrain. High abrasion resistance ensures longer wear life.

2. Flexing Endurance

Using flex testers like the Bally or Ross Flex, labs simulate thousands of walking steps under different temperature and moisture conditions. This test helps predict long-term comfort and structural integrity.

3. Slip Resistance (Anti-Skid Testing)

Slip resistance is crucial in wet, oily, or uneven surfaces. Labs test boots on ceramic and steel surfaces under both dry and lubricated conditions using EN ISO 13287 or ASTM F2913 methods.

4. Puncture Resistance

Military boots often include puncture-resistant midsoles. This test simulates nails or sharp debris piercing the sole and ensures protective layers resist intrusion per EN ISO 20344 or ASTM standards.

5. Impact and Compression Tests

Boots are tested for toe protection against falling objects or compression. Steel or composite toe caps are evaluated under controlled impact levels, as per ISO or ASTM F2412/F2413 guidelines.

6. Waterproofness and Breathability

Gore-Tex or similar membranes in tactical boots must keep water out while allowing moisture vapor to escape. Testing includes dynamic waterproof tests and moisture vapor transmission rate (MVTR) analysis.

7. Thermal Insulation Tests

Boots used in desert or arctic conditions must regulate internal temperature. Labs use thermal manikins or environmental chambers to simulate extreme conditions and evaluate heat retention or dissipation.

8. Chemical and Oil Resistance

Outsoles and upper materials are exposed to fuels, oils, acids, and chemicals to test for degradation. This is vital for boots used in hazardous material or combat zones.

9. Shock Absorption and Cushioning

Cushioning underfoot is measured using impact energy return tests, ensuring comfort under prolonged marching or running conditions.

Standards Followed in Military Boot Testing

A Footwear Testing Lab certified to ISO/IEC 17025 conducts tests according to stringent industry and military protocols, including:

MIL-STD-810G/H – U.S. military standard for environmental testing

ASTM F2412 / F2413 – Safety footwear performance requirements

EN ISO 20344 / 20345 – European standards for protective footwear

SATRA TM standards – For durability, safety, and slip resistance

CSA Z195 – Canadian military and tactical footwear requirements

Adhering to these standards ensures boots can be approved for procurement by government and defense agencies.

Benefits of Advanced Testing for Manufacturers and Defense Agencies

✅ Reduced Product Failures

Testing identifies weaknesses before products are deployed, reducing the risk of failure in mission-critical environments.

✅ Increased Trust and Procurement Success

Defense agencies are more likely to approve and reorder from manufacturers who demonstrate rigorous testing compliance.

✅ Global Market Access

Complying with international military and tactical standards enables manufacturers to export to allied nations with confidence.

✅ Enhanced Innovation

Testing feedback helps in improving design, materials, and performance features for future models.

Real-World Example: Tactical Boot Failure

In a widely reported case, a military boot contract was canceled because the outsole delaminated in desert heat, causing severe discomfort and injuries. Post-analysis revealed the manufacturer had not conducted adequate heat resistance testing. A certified Footwear Testing Lab could have prevented this by simulating high-temperature flex and adhesion degradation in controlled environments.

Choosing the Right Footwear Testing Lab

When selecting a testing partner for military boots, look for:

ISO/IEC 17025 Accreditation

Experience with military-grade footwear and standards

Wide test capabilities (mechanical, chemical, environmental)

Fast turnaround and detailed reporting

Partnering with the right Footwear Testing Lab ensures your tactical gear meets the high expectations of those who depend on it most.

Final Thoughts

Military and tactical boots are far more than just footwear—they are mission-critical equipment. Their failure can compromise safety, efficiency, and operational success. That’s why rigorous, advanced testing by a specialized Footwear Testing Lab is non-negotiable.

By performing in-depth durability, impact, slip, and environmental tests, these labs help manufacturers meet military standards, minimize field failures, and protect the lives of those on the front lines.

Nike Motiva

According To Nike

No matter how you choose to move, Nike believes the product you wear should make exercise better, whether you’re motivated by a feeling or a finish line. Just as the very definition of sport continues to become more personal, variable and redefined across activities, Nike has fundamentally shifted how it serves and supports women’s fitness journeys — whatever that may look like.

The Nike team noticed that the majority of women logging their first workout on the Nike Run Club app were averaging a 13-minute mile. But they weren’t just running at that pace — they were fluctuating between walking, jogging, running, starting and stopping throughout their activity.

This observation sparked an exploration of new ways to better serve this athlete’s unique experience on the go through meaningful innovation.

Drawing on its culture of innovation, Nike designers and scientists met with more than 1,000 people whose fitness routine consists of walking, jogging and running to better understand their needs. Through hundreds of interviews and focus group hours both in the Nike Sport Research Lab and in people’s communities, Nike teams knew that stop-start-slow pacing patterns often result from fatigue, causing discomfort and frustration. And they knew that this experience was keeping people from truly enjoying their movement — sometimes well before they could enjoy it or feel the physical and mental payoff of their workouts. This motivated teams to focus on creating a shoe that would help make exercise more enjoyable and ultimately motivate people to keep going.

Enter Nike Motiva, a new shoe designed to help you move more with comfort and ease. “In designing Motiva, we really went after removing distractions, addressing the discomfort that can go along with how you feel both during and after an activity,” says Dr. Emily Farina, Principal Researcher in the Nike Sport Research Lab. “The result is a shoe that can help reduce disruptions in your stride to make moving feel smoother — and, we hope, help you want to come back for more.”

All-New Rocker Geometry Looking at insights, the Nike team understood that at a slower pace, people are more likely to strike the ground heel first. The sole of the Nike Motiva features an exaggerated rocker that helps provide a smooth transition as you move forward. The rocker helps ease your foot to the ground after heel impact before helping to roll your foot forward to push back off for your next step.

Comfortable Cushioning The Nike Motiva was built to make every move more comfortable.

The more cushioning underfoot, the softer and more comfortable an experience on the go can be. Full-length Cushlon 3.0 foam in the Nike Motiva midsole is designed to provide cushioning to help soften the impact as your feet hit the ground. New ComfortGroove bumps on the outsole help make the underfoot experience even softer, compressing where and when you need it. Any bit of energy return a shoe could give back to the wearer means they may feel less fatigued. Less work, more fun.

A soft foam waterfall collar hugs the ankle and heel, while an internal half-bootie helps you seamlessly get the shoe on and off with ease.

All-New Fit Throughout testing, testers told Nike that a narrow shoe is not their preferred fit. So the team built the Nike Motiva on a new, data-driven last, delivering the widened forefoot, arch and toe box testers asked for.

The Nike Motiva will be available in May at nike.com and in select Nike stores and other specialty retailers.

What to know

The Nike Motiva is a new shoe made for walking, jogging and running with comfort and ease.  

The new rocker geometry, last and full-length cushioning provide a plush and smooth ride for varied activities and fluctuating paces. 

Drawing on its culture of innovation, Nike designers and scientists leveraged insights from women logging workouts on the Nike Run Club app and interviews with more than 1,000 people who walk, jog and run to understand their unique needs and create a shoe that made all movement more enjoyable. Less work, more fun.

2021 Lexus RX 450h is a comfy crossover with troublesome tech

New Post has been published on https://appradab.com/2021-lexus-rx-450h-is-a-comfy-crossover-with-troublesome-tech/

2021 Lexus RX 450h is a comfy crossover with troublesome tech

The expressively styled Lexus RX is smooth and coddling.

Craig Cole/Roadshow

The 2021 Lexus RX 450h F Sport hybrid crossover is sinuous, frugal and impressively quiet — exactly what I want in a luxury vehicle. There is, however, one aspect of this Lexus that’s unforgivable, a mortal sin that drags down an otherwise pleasant vehicle: the infotainment system. 

Like

Stellar Mark Levinson sound system

Spacious and comfortable backseat

Exemplary refinement

Don’t Like

Loathsome infotainment system

Too-aggressive exterior styling

Meh real-world fuel economy

Hybrid versions of the RX come standard with all-wheel drive, but this example is also fitted with the F Sport package, which includes dress-up items like a unique grille, aluminum pedal covers, 20-inch wheels and even performance dampers. For extra sportiness, a $970 handling package is also offered, bringing an adaptive suspension system, retuned power steering and more goodies to the table. Beyond those F Sport upgrades, my tester features the Black Line Special Edition package. The good news is this upgrade costs just $685 and includes special body-side graphics, a black grille surround and a Halliburton Edge lightweight two-piece luggage set. The bad news is the Black Line Special Edition package is limited to just 750 gas-powered RXs and 250 hybrid models.

The Lexus RX’s styling is certainly aggressive, with its comically large grille, angular headlamps and chiseled surfacing, but its interior is much more restrained and pleasant. The cabin’s quality is stellar and its materials are generally very good. The headliner and roof pillars are wrapped in a flannel-like fabric, soft plastics are used liberally throughout and nearly all the switches and knobs feel slickly lubricated. Sure, you’ll find a smattering of Toyota-sourced buttons here and there; stuff you get in, say, a Camry, but these carryover controls are well hidden and hardly objectionable.

Just behind this Lexus’ unusually deep dashboard, the front bucket chairs are all-day comfortable and attractive, rendered in black and white with contrasting blue stitching, a combo that’s also part of the Black Line Special Edition package. Storage space up front is good, consisting of a decently sized bin under the center armrest, a few other small cubbies on the console and generously proportioned front door pockets that pop outward when you pull on them. Moving rearward, the RX’s backseat is nearly sprawl-out spacious, with plenty of legroom and a decent amount of noggin space. Comfortable cushions provide great support, with the lower one being a nice distance above the floor for a chair-like seating position. Providing easy access, this Lexus’ rear doors open nice and wide.

But now for some bad news. If there’s a worse infotainment system than what’s offered in this Lexus, I’m not aware of it. With a bewildering user interface as well as a clunky and difficult-to-use control pad on the console, this multimedia system is half laptop, half low-end Android tablet and all kinds of terrible. Not only is the menu structure confusing, the track pad you use to navigate through it is kludgy, making even simple tasks a distracting chore. Rubbing salt in the wound, this RX 450h is also fitted with the top-shelf 12.3-inch screen (an 8-incher is standard), which is bundled in a $3,365 options package, so you’re paying thousands more for an awful experience. At least that outlay also gets you embedded navigation and a superb Mark Levinson sound system that makes even highly compressed MP3s and muddy satellite radio come alive. While a bit of a reach, the RX’s infotainment screen is touch-enabled, so you can skip the trackpad, but only if your arms are lanky enough. Thankfully, this system also supports Apple CarPlay and Android Auto (as well as Amazon Alexa), so you don’t have to use the infotainment system any longer than it takes to plug your phone in. The vehicle’s six USB ports ensure everyone’s mobile devices are fully juiced; a wireless charging pad is also available.

The RX’s interior is extremely well built and refined, though its infotainment tech leaves much to be desired.

Craig Cole/Roadshow

The Lexus RX was updated in 2020, gaining a stiffened structure and revised suspension for better handling. This year, the vehicle gains some new technology, including blind-spot monitoring and rear cross-traffic alert, both of which are now standard across the range. Auto-dimming, power-folding mirrors are included at no extra charge, too, as is Lexus Safety System Plus 2.0, a suite of driver aids that includes daytime cyclist detection, low-light pedestrian detection, road sign recognition and lane-keeping assist. Thankfully, I have not had an opportunity to test the pedestrian-detecting systems, but the lane-keeping aid is gentle yet quite effective.

Underway, the RX 450h is one smooth operator. Whether you’re traversing frost-heaved highways, tiptoeing along a cratered dirt road or just cruising around your subdivision, this Lexus’ ride is always sinuous. Even rolling on 20-inch wheels, small expansion joints barely register and larger impacts are easily deflected, all with no harshness or gritty vibration percolating through to the passenger compartment. Despite its smooth ride, the RX 450h’s body is decently controlled. Sure, it could feel a bit tighter in corners and it might be nice if the steering were quicker and heftier, but the whole chassis feels so well balanced that these changes aren’t necessary, plus they might ruin the fluffy ride, which would be a shame.

Refined, punchy and economical, there’s little to complain about regarding the RX 450h’s powertrain. 

Craig Cole/Roadshow

Matching its over-the-road refinement, the RX’s cabin remains incredibly silent, quieter than naptime in a nursing home, with almost no wind, tire or engine noise being heard. The RX 450h’s hybrid powertrain is built around a 3.5-liter V6, one augmented by two electric motor-generators up front that form a continuously variable transmission, and a separate motor at the rear, which provides all-wheel drive. Whispering while it works, this arrangement provides a net 308 horsepower, though a torque figure is not listed because the math with hybrids is weird. On its own, however, the V6 engine whips up 247 pound-feet of twist. The RX 450h’s easy handling and all-wheel drive add immensely to my confidence one day as the weather goes from drab to dangerous, with a winter storm dumping sleet on the roadways.

Stand on the accelerator and this Lexus scoots. Performance, while not awe-inspiring, is still very good, the engine sounding like it’s operating far off in the distance rather than a few inches ahead of your toes. The hybrid parts of this drivetrain are similarly polished, barely drawing any attention to themselves. The brake pedal is also friendly, with a seamless transition between regenerative and friction braking. For added versatility, the RX 450h offers an EV mode, which allows you to run it solely on electrons. The onboard battery pack has enough juice for you to sneak down a cul-du-sac or into the garage without running the engine, but as soon as you go too fast or prod the throttle too aggressively the engine fires up. Remember, this is not a plug-in hybrid, so electric-only range is not the primary focus.

Cutting fuel consumption, however, is one of this Lexus’ main objectives. Expect 31 miles per gallon in the city and 28 mpg on highway drives. In mixed use, the RX 450h should return 30 mpg, however, in the real world I only average around 25.1, a disappointing score. It’s typically a breeze to meet or even exceed advertised fuel-economy scores in Toyota hybrids, which makes this performance (or lack thereof) a bit of a surprise.

The Lexus RX is something of a mixed bag.

Craig Cole/Roadshow

With its upscale interior, refined manners and, yes, unfortunate infotainment tech, a base 2021 Lexus RX 450h starts at just shy of $49,000, including $1,025 in destination fees. That’s about $2,650 more than an entry-level, front-wheel-drive, non-hybrid RX 350. As it sits, this F Sport example checks out for $59,380, a figure goosed by a few add-ons like a $200 wireless charger, $640 heated and ventilated front seats, $1,365 for parking assist and a 360-degree camera system, plus a few additional goodies. Still, that outlay gets you a family-friendly vehicle that’s more docile and refined than the sportier Acura MDX and, thanks to its aggressive styling (which you may or may not love), more visually interesting than a Lincoln Nautilus or Mercedes-Benz GLC.

There’s an abundance of luxury crossovers available today, great examples from German, American and Asian automakers. Plenty of them offer upscale interiors and loads of fancy features, but few are as refined, fuel efficient — and in one particular way — frustrating as this mostly likable Lexus.

Are Concrete Molds Waterproof?

Bridges could use long beams of excessive-power concrete to decrease the variety of spans required. Occasionally, other structural wants might require high-energy concrete. If a construction have to be very inflexible, concrete of very excessive strength could also be specified, even a lot stronger than is required to bear the service loads. Strengths as high as a hundred thirty MPa (18,900 psi) have been used commercially for these causes https://columbiamachine.com/concrete-molds/.

A wide number of tools is used for processing concrete, from hand tools to heavy industrial machinery. Whichever tools builders use, nonetheless, the target is to produce the desired building material; components must be correctly mixed, positioned, formed, and retained within time constraints.

Accelerators velocity up the hydration (hardening) of the concrete. Typical materials used are calcium chloride, calcium nitrate and sodium nitrate.

Air entrainment admixtures are often utilized in freeze–thaw climates to minimize the potential for frost injury. Pervious concrete additionally permits rainwater to filter via roads and parking heaps, to recharge aquifers, as an alternative of contributing to runoff and flooding.

Larger earthquakes can generate very massive shear loads on buildings. These shear loads topic the construction to both tensile and compressional masses. Concrete constructions without reinforcement, like different unreinforced masonry buildings, can fail during extreme earthquake shaking. Unreinforced masonry constructions represent one of the largest earthquake dangers globally. These dangers could be decreased through seismic retrofitting of at-threat buildings, (e.g. faculty buildings in Istanbul, Turkey).

<h2>Tips For Using Concrete In Architecture</h2>

Admixtures are added to switch the treatment rate or properties of the fabric. Mineral admixtures use recycled materials as concrete ingredients. Conspicuous supplies embody fly ash, a by-product of coal-fired energy plants; ground granulated blast furnace slag, a byproduct of steelmaking; and silica fume, a byproduct of industrial electric arc furnaces.

However, use of chlorides may trigger corrosion in steel reinforcing and is prohibited in some countries, so that nitrates could also be favored, despite the fact that they are less effective than the chloride salt. Accelerating admixtures are especially useful for modifying the properties of concrete in chilly weather. Concrete is robust in compression, as the combination effectively carries the compression load. However, it's weak in pressure because the cement holding the aggregate in place can crack, allowing the construction to fail. Reinforced concrete provides either metal reinforcing bars, steel fibers, aramid fibers, carbon fibers, glass fibers, or plastic fibers to carry tensile hundreds.

Very low-strength—14 MPa (2,000 psi) or much less—concrete could also be used when the concrete must be light-weight. Lightweight concrete is often achieved by including air, foams, or lightweight aggregates, with the facet impact that the strength is lowered. For most routine makes use of, 20 MPa (2,900 psi) to 32 MPa (4,600 psi) concrete is commonly used.

Its usage worldwide, ton for ton, is twice that of metal, wooden, plastics, and aluminum mixed. Globally, the prepared-combine concrete trade, the most important segment of the concrete market, is projected to exceed $600 billion in income by 2025. In contrast to modern concrete structures, the concrete used in Roman buildings was often covered with brick or stone. Wet-combine shotcrete, nevertheless, includes the usage of pre-mixed concrete. The concrete has already been prepared and therefore only involves one pump.

Bacteria similar to Bacillus pasteurii, Bacillus pseudofirmus, Bacillus cohnii, Sporosarcina pasteuri, and Arthrobacter crystallopoietes enhance the compression energy of concrete through their biomass. Not all bacteria increase the energy of concrete considerably with their biomass.[citation needed] Bacillus sp. can reduce corrosion of reinforcement in strengthened concrete by up to 4 occasions. pasteurii increases resistance to acid.[citation needed] Bacillus pasteurii and B.

Any interruption in pouring the concrete may cause the initially placed materials to begin to set earlier than the next batch is added on high. This creates a horizontal airplane of weakness called a chilly joint between the two batches.

The general embodied vitality of concrete at roughly 1 to 1.5 megajoules per kilogram is therefore decrease than for many structural and construction supplies. Another strategy to mass concrete structures that minimizes cement's thermal byproduct is the usage of roller-compacted concrete, which uses a dry combine which has a a lot decrease cooling requirement than standard moist placement. It is deposited in thick layers as a semi-dry material then roller compacted into a dense, sturdy mass.

Once the combo is where it must be, the curing course of have to be controlled to ensure that the concrete attains the specified attributes. During concrete preparation, various technical particulars could have an effect on the quality and nature of the product. Modern concrete is often prepared as a viscous fluid, so that it might be poured into forms, that are containers erected within the field to offer the concrete its desired form. Concrete formwork could be prepared in a number of methods, similar to slip forming and metal plate development. Alternatively, concrete can be blended into dryer, non-fluid varieties and utilized in manufacturing facility settings to manufacture precast concrete products.

The upside to using moist-mix shotcrete is that dry-combine shotcrete creates extra waste (excess powder that falls to the floor), more rebound off the wall, and moist-mix shotcrete can place a bigger quantity in a smaller amount of time. In the years following the development of the Ingalls Building in 1904, most excessive-rise buildings had been manufactured from metal.

sphaericuscan induce calcium carbonate precipitation in the floor of cracks, including compression energy. Pervious concrete is a mixture of specially graded coarse combination, cement, water and little-to-no fine aggregates. Mixing the ingredients in a fastidiously controlled course of creates a paste that coats and bonds the mixture particles.

<h2>Www.designingbuildings.co.uk</h2>

Construction in 1962 of Bertrand Goldberg's 60-story Twin Towers in Chicago sparked renewed interest in using strengthened concrete for high-rises. The Pantheon has exterior foundation partitions which are 26 toes broad and 15 ft deep and made from pozzolana cement (lime, reactive volcanic sand and water) tamped down over a layer of dense stone mixture.

In the 1980s, coinciding (apparently by likelihood) with the "Right to Buy" laws being brought in, it was discovered that many of the publish-struggle concrete council houses had been faulty. The defect stemmed from the poor high quality steel rods used of their construction, which were discovered to endure corrosion and subsequent metallic fatigue over time. Though PRC houses bought previous to 1984 could have certified for presidency grants to help restore them, these grants are not available and present owners are forced to pay the repair burden alone. Even if you have appropriate trendy development house insurance, such work is unlikely to be covered in your policy. As mentioned above, concrete could be very sturdy in compression, but weak in tension.

<h3>Characteristics Of Concrete</h3>

forty MPa (5,800 psi) concrete is instantly commercially obtainable as a more sturdy, though costlier, possibility. Higher-energy concrete is usually used for bigger civil initiatives. Strengths above forty MPa (5,800 psi) are sometimes used for particular building components. For instance, the decrease flooring columns of excessive-rise concrete buildings might use concrete of 80 MPa (eleven,600 psi) or more, to keep the size of the columns small.

While insulation reduces vitality loss by way of the building envelope, thermal mass makes use of walls to retailer and release energy. Modern concrete wall techniques use both exterior insulation and thermal mass to create an power-environment friendly building. Insulating concrete forms (ICFs) are hole blocks or panels made of both insulating foam or rastra that are stacked to type the shape of the partitions of a building and then full of reinforced concrete to create the structure. Energy necessities for transportation of concrete are low as a result of it is produced domestically from native sources, typically manufactured inside one hundred kilometers of the job website. Similarly, relatively little energy is used in producing and combining the uncooked materials (although massive amounts of CO2 are produced by the chemical reactions in cement manufacture).

It is predicted that to keep pace with calls for in South East Asia and sub-Saharan Africa, cement manufacturing may have to extend by 25% by 2030. A load cell is fitted to the tensile tester to measure tensile pressure. In addition a tensile test is commonly used to measure other properties of materials corresponding to Young’s modulus of elasticity, yield stress, elongation, pressure and ultimate tensile stress.

<h3>Concrete In Architecture ( : A Material Both Stigmatised And Celebrated</h3>

Once in place, concrete offers nice energy efficiency over the lifetime of a building. Concrete partitions leak air far less than those made from wooden frames. Air leakage accounts for a large share of power loss from a home. The thermal mass properties of concrete increase the effectivity of each residential and industrial buildings. By storing and releasing the power needed for heating or cooling, concrete's thermal mass delivers yr-round advantages by decreasing temperature swings inside and minimizing heating and cooling prices.

The hardened concrete contains interconnected air voids totaling roughly 15 to 25 %. Water runs through the voids within the pavement to the soil beneath.

Lowa Tempest Hiking Shoes (8) - $20

(originally $135) - 2 years old, I used it once since I preferred my hiking boots  Weight 2 lbs. 4 oz.

“This is a carry-anything backpacking boot disguised as a light hiker,” says one tester, who typically humps 50-pound loads in higher-cut, heavier-weight boots. All that gumption comes from a midsole that’s borrowed from Lowa’s burlier boots. A full-length nylon shank provides stiffness underfoot, and a dense PU midsole gives long-lasting shock absorption. A one-inch-thick PU pad lies under the heel for extra cushion in this all-important strike zone.

Compared to the other shoes in the test, which have spongier, more compressible EVA midsoles, the Tempest has rigid underfoot support that kept sharp rocks from poking through, even when testers shouldered up to 55 pounds on the rugged Tanner Wash route. One tester put the Tempest “through hell” on a multiday off-trail route down to Lava Falls; the shoe’s double-stitched, split-grain leather protected him against knife-edged boulders, though after 25 miles the relentless abrasion caused damage to the stitching on the outside edge of the toe area. (Note: No other shoe endured this level of punishment.)

Despite the stiffness of the sole and upper, one tester wore the Tempest straight out of the box on a 30-mile backpacking trip down the Hermit Trail and didn’t get a single blister. Fit favors low- to mid-volume feet; consider going up a half size. https://www.backpacker.com/gear/gear-review-lowa-tempest-lo-hiking-boot

When Scuba Cylinders Go Bad

Depending on where you’re diving, you may know them as scuba cylinders, tanks or bottles. These aluminum or steel vessels retain our breathing gas at incredibly high pressures. Modern regulators then convert that high-pressure gas to intermediate and then ambient pressure, meaning that, whatever your depth, you should receive a smooth flow of breathing gas.

When it comes to our dive equipment, we often forget about our scuba cylinder. Yet it is vital. We often take for granted that our cylinders are safe, and that dive staff has tested and properly cared for them. But if a cylinder “goes bad,” it can have life-changing (or even life-ending) consequences for the diver or whomever is filling it. Scuba cylinders leave the factory tested to strict engineering standards. However, once in use — much like your car or motorcycle — the onus and responsibility for cylinder care lies with the user.

Impact damage to cylinder walls, valve damage and moisture entering the internals of the cylinder are most concerning. With that in mind, here are some practical hints and tips when it comes to taking care of scuba cylinders.

Care of scuba cylinders

Don’t leave your cylinder standing up unattended or transport it in an upright position, unless you secure it well. Impact can damage cylinders, which compromises their structural integrity. Don’t leave them in a position where they may fall over. Also, if your cylinder rolls over someone’s toes on a boat, you will not be popular.

Impact damage can also affect cylinder valves. When transporting cylinders in a vehicle, lay them down, but not in a position where other items can knock into or crush the valve. The vehicle’s movement can also negatively impact a cylinder valve.

Be gentle with the cylinder valve. Don’t wrench it open or shut it forcefully. Closing the valve extremely hard can damage the valve seat. Similarly, when opening the valve, turn gently until you reach the “fully on” position, then make a small semi-turn back. If you’re technical diving, leave the cylinder fully open to avoid confusion on gas shut-downs.

Just as with your other gear, rinse the valve and cylinder with fresh water at the end of your dive trip.

Always store your cylinder with a small amount of gas inside, e.g. 200 to 300 psi or 10 to 20 bar. This reduces the chances of moisture entering the tank. If you’re filling your tank, don’t inadvertently force moisture into the cylinder when filling. Be sure the cylinder valve is dry before connecting the compressor whip. An experienced compressor operator will give the cylinder and whip a little blast or wipe. This will remove any moisture before connecting the two.

Only a reputable dive center or trustworthy source should fill your cylinder. Moisture can contaminate the tank from poorly maintained compressors where the air is not correctly filtered. This leads to internal corrosion and potentially bad consequences.

Cylinder testing

Cylinders require regular testing to check their strength and function. Depending on where you are, a regular combination of visual and hydrostatic testing will be necessary.

If you’re using or, especially, filling a cylinder, always check that it is “in test.” Look for the IDEST sticker or stamp, or ask the dive operator for evidence that the cylinder is serviced. And don’t be surprised if a dive center won’t fill your cylinder without evidence that you’ve hof the required testing.

Visual testing is often an annual affair. Dive centers will completely drain the cylinders and remove the valves. Then, the servicing engineer will visually inspect the tank walls for damage, pitting and corrosion. He or she will often service the valve at the same time.

Hydrostatic testing, sometimes known as a “hydro test” by divers, sometimes alternates — depending on location — with the simpler visual test. During a hydrostatic test, the scuba cylinder is filled with water and pressurized to a massive 5/3 of its working pressure. Testers measure the “flexing” of the cylinder wall to ensure that it still retains elasticity and structural safety. Water can’t be compressed. Therefore, if the cylinder is defective it won’t explode if it fails, as it would when pumped with compressed air.

When scuba cylinders go bad

Of everything that could go wrong with a cylinder, luckily, explosions are rare. Of those few recorded failures, most appear to be with the sometimes-more brittle aluminum cylinders. These instances are statistically very small in comparison to the millions of cylinders in circulation worldwide, but there are a few other issues that can arise with cylinders.

Always undertake visual checks, particularly when renting a cylinder. When the shop assigns you a cylinder, look for a service or test sticker or stamp on its side. Requirements and markings vary from location to location so if you’re not sure, ask one of the dive team.

Dive center staff often load dozens of cylinders from boats and trucks and inevitably tanks may become scratched or sometimes damaged. Expect light scratches on the exterior, but if you see severe, deep scratches or dents, point them out to dive center staff for further investigation and, also, for their safety when they fill the tank.

Internal corrosion can lead to a full failure when filling a cylinder, but more likely on the first instance is contamination of breathing gas. Complete a pre-dive safety check on each dive and take a few breaths from your regulator. Does the gas taste strange? Tell the staff if you have any concerns.

Common Problems

Leaks are one of the most common wear-and-tear issues when it comes to cylinders. When you first set up your scuba unit, make sure the O-ring in the cylinder valve is in good condition. Listen for leaks and hisses. If gas is escaping, try re-seating your first stage or ask the dive crew to change the O-ring. If the hissing is coming from where the valve joins the tank, it may not be tightened to the correct torque setting. Equally worrying, there may be tiny cracks at the neck of the tank. Either way, report it to the dive crew.

Cylinder valves that are stiff to open, close or turn are relatively common as they near their service date. If the valve itself is leaking, report your concerns.

Don’t leave the care, regular testing and maintenance of your own scuba cylinders as an afterthought to your equipment preparation. And if you’re renting a cylinder, make sure it’s been tested, is in reasonable condition and that the gas tastes okay before diving with it. If in doubt, speak with the dive operator.
