Antimicrobial

How do the Spenco Polysorb Cross Trainer insoles help to control that pesky foot odor? Easy. They are treated with Silpure’s silver antimicrobial technology. Not only does this help to control odor but it also helps to prevent blisters.

What is silver antimicrobial technology? It contains very fine crystals made of silver, and they release, when needed, silver ions to fight bacterial growth. The shape and size of the silver particles are carefully controlled during production. This helps Silpure to avoid discoloration in the fabric (can occur when using other treatments with silver antimicrobial technology).

Having your Spenco Polysorb Cross Trainer insoles treated with Silpure silver antimicrobial technology will provide them with long-lasting freshness and cleanliness, even after being washed multiple times. It is a popular treatment on bedding, upholstery, and towels that are vulnerable to microbial growth. Silpure’s technology is BPR compliant, US EPA registered, and OekoTex listed. It is both safe and effective. For more tips on odor control, check here.

Cushioning

Spenco Polysorb Cross Trainer insoles provide your feet with the cushioning that they need to power through the day, whether you’re walking, running, or playing sports. And they don’t just provide cushioning to your heels and arches, either.

Spenco knows that the forefoot is often overlooked in the design process of insoles and shoes. Because of this, people tend to struggle with blisters, sliding around, the insoles bunching up, more pressure on their toes, and other discomforts.

The SBR (styrene-butadiene rubber) cushioning gives you premium cushioning and optimal energy return so that you can stay comfortable during high-impact activities. The cushioning makes the Spenco Polysorb Cross Trainer insoles more durable. This means you won’t have to replace them as often because the forefoot won’t wear out as easily as it would in other, less cushioned insoles.

SBR foam is a popular material to use for the inner layer of orthotic devices because it provides cushioning, bounce back, and pressure relief. For other insoles geared towards high-impact activities, check here.

Shock Absorption

Whether you’re on your feet long enough for a stroll to the mailbox or you work long hours on hard floors or you go for long runs, your feet and body are exposed to the risk of foot pain. With every step that you take, your feet strike the ground. Therefore, they take the beating, and sometimes it causes pain.

If you do experience any pain in your feet, ankles, legs, or lower back, you may benefit from the shock absorption provided by Spenco Polysorb Cross Trainer insoles. The shock absorption you’ll receive can help to decrease the discomfort and pain that your muscles, ligaments, and joints feel from your feet to your back.

The shock absorption also returns energy to your feet, which will keep them comfortable, supported, and more energized for your activities. You can even find some relief in shoes with shock absorption.

How does shock absorption work? Spenco Polysorb Cross Trainer insoles absorb shocks by dispersing the shocks and stress from each foot strike across your whole foot, instead of focusing the strain on your heels or arches. By dispersing the impact across your entire foot, you’ll be able to find some relief in your feet, ankles, legs, and back.

Support

Something that’s important to your feet, no matter how much or how little you use them, is the amount of support they receive from your socks, shoes, and insoles. Standing, walking, running, and playing sports all require that your feet have some form of support. Without it, your feet and ankles are less stable, creating a higher likelihood of injuries and pain. Here is a great option for a supportive sock.

Spenco Polysorb Cross Trainer insoles are designed for those with a medium arch. They will provide too much support for some people with flat feet, and not enough support for some people with high arches. It’s always wise to consult your Dr. if you have any kind of foot condition, before shopping around. It’s best to know what you need from the start.

The support that is provided by the Polysorb Polyurethane Foam provides support for both your heel and your arch. A lot of times, you’ll find that insoles will focus on one area or the other. However, Spenco Polysorb Cross Trainer insoles know that the best way to provide adequate support is to put it where you need it - both in your arch and your heel.

Arch

If you don’t quite have flat feet, but you also don’t quite have high arches, then you need to be looking for insoles with a neutral arch. This category is for the standard foot which distributes weight fairly evenly on its own. Spenco Polysorb Cross Trainer insoles are great for lasting performance and less stress under your weight. If you need insoles for flat feet, check here.

Spenco Polysorb Cross Trainer insoles are designed specifically for those with neutral arches. This category of insoles is great for those who suffer pain in their heels or ball of their foot. The insole, as a whole, provides shock absorption that will lessen the pressure on those areas. The neutral arch support will also help to distribute the weight even more evenly than your natural movement.

The Polysorb Polyurethane Foam is lightweight and provides heel and arch support. It has the capability to alleviate pain and discomfort caused by plantar fasciitis, heel pain, and foot fatigue. Even if you have the “standard” neutral arch, you can still have feet that tend to land with more pressure in certain areas, causing foot fatigue. If you need insoles for high arches, check here.

Forefoot

The forefoot is the portion of the foot that many designers forget about when making insoles, socks, and shoes. The most attention is focused on your heels and arches. These areas do need attention, but so does your forefoot.

Without the proper cushioning and support in your forefoot, you are susceptible to pain, burning, itching, cracks, or blisters on the ball of your foot. Here are some tips for blisters. With Spenco Polysorb Cross Trainer insoles’ crash pad on the forefoot, it will reduce the amount of pressure put onto your forefoot with every footstrike. The crash pad can also help to reduce pain from metatarsalgia and Morton's neuroma.

Metatarsalgia is a term that refers to a foot condition in the ball of your foot (the metatarsal region just before toes). This condition can be very painful and affects your joints and bones in that area. With the crash pad, you can alleviate the pain associated with this condition.

Another condition the Spenco Polysorb Cross Trainer insoles can help with is Morton’s neuroma. This term refers to an inflamed nerve in the third intermetatarsal space (ball of your foot). The condition is caused by consistent compression on a portion of your plantar nerve that goes between your metatarsal bones. Morton’s neuroma can cause a lot of pain. Spenco Polysorb Cross Trainer insoles are here to help.

Fit

There are some insoles on the market that come in just one size. With those insoles, you have to measure the insole against your shoe, trace a guideline, trim it with sharp scissors, and then put it in your shoe. Unless you have feet that are very narrow or very wide, wouldn’t it be more convenient to get insoles with specific sizes offered?

Spenco Polysorb Cross Trainer insoles are offered in seven different sizes. The women’s sizes range from five to twelve and a half. The men’s sizes range from eight to thirteen and a half. It is recommended that, if you wear a half size, you order a size down.

These are supposed to be made to fit any style of shoe, however, some consumers have reported that they were too wide for their dress shoes or running shoes. It may help to know beforehand that the insoles are just over four inches wide at their widest area. If you need trimmable insoles, check here.

Relief

Your arch in your foot is made up of tarsal and metatarsal bones. Your feet also have numerous ligaments and tendons from toe to heel. The bones, ligaments, and tendons are what enable you to stand and walk. They are what supports your weight and help your weight to be distributed evenly, providing better balance.

If your bones, ligaments, and tendons aren’t enough to efficiently distribute your weight on their own, it will cause excess pressure to be put upon the ball of your foot and your heel. When this happens, you’re likely to experience pain.

Luckily, Spenco Polysorb Cross Trainer insoles can pick up the slack to provide you with balance and more even weight distribution. The neutral arches, crash pad in the forefoot, and SpenCore Heel Plug cradling your heel, this insole will help keep you stable without pain. Here are some other products to look into for foot pain.
