Spenco Polysorb Cross Trainer insoles generally last around six months to a year with regular use. Of course, this depends on how often you use them, what kinds of activities you're doing, and your individual walking or running style.

According to our research, they start off providing good comfort and support, especially if you have high arches. They're thick, and that cushioning works well for absorbing shock during athletic activities, but it might make your shoes a bit snugger. Some folks find they need to take out the original insoles from their shoes to fit these in because of the thickness.

It's really important to make sure they fit right from the start. Some people notice issues like heel slippage or pressure if the insoles aren't properly trimmed to fit their shoes. As time goes on, they might compress a little, which can help with initial fitting problems.

How long they last also depends on how you use them. Lots of high-impact activities can wear them out faster, while more moderate use might keep them in good shape longer. If they start feeling less supportive or comfortable, it might be time for new ones.

For those with flat feet, the high arch support might take some getting used to. If this sounds like you, you might want to ease into wearing them to let your feet adjust.

And if after a while they’re still not your jam, it might be worth checking out other options that better suit your foot type.

Overall, they're built to be durable and perform well, but how long they last and how comfortable they feel can vary, so consider your specific needs and activity levels to get the most out of them.

The Spenco Polysorb Cross Trainer insoles are pretty popular, especially if you're into sports or have an active lifestyle. From what we've gathered, they're actually a solid choice if you've got high arches. The manufacturer mentions their comfy feel and good shock absorption, which is a big plus.

They come with an EVA forefoot cushion and Spencore material, and both are good at handling shock. This means they can help spread out pressure across your foot, which is great during high-impact activities and could make things more comfortable if you've got those high arches.

However, when it comes to how long they last, opinions differ. Some folks are happy with how durable they are, while others say they wear out faster than expected, especially if they're used a lot.

We've found that some people notice they develop holes or just don't last as long as previous versions. It seems like it might depend on how you use them and your specific foot needs.

A lot of people still love the support and cushioning and get them for all sorts of shoes, which suggests that comfort and support might overshadow any durability concerns for most.

But if you're really worried about them lasting, you might want to check out alternatives like Powerstep, which some say holds up better over time. Also, buying from a place with a good return policy isn't a bad idea—it lets you test them out and see if they fit the bill before fully committing.

In short, the Spenco Polysorb Cross Trainer insoles do a great job with support and comfort, especially for high arches. They might not last forever for everyone, but they're definitely worth considering for their comfort and support.

When you're weighing up Spenco Polysorb Cross Trainer insoles against custom orthotics, there's a lot to think about, especially stuff like support, comfort, and how much you're willing to spend.

Design and Comfort

The Spenco Polysorb Cross Trainer insoles come in sizes that fit both men and women, specifically Women's 7-8.5 and Men's 6-7.5, as per the manufacturer. They’re built for people who do high-impact activities, offering solid arch and heel support. Plus, they have a 4-way stretch fabric to help avoid blisters and manage odor, along with Spencore material for better shock absorption and comfort.

Custom orthotics, on the other hand, are made just for you. They're molded to fit the unique shape of your foot and are often prescribed by healthcare professionals to tackle specific issues like severe foot deformities or ongoing pain.

Materials and Construction

The Spenco Polysorb insoles use lightweight polysorb polyurethane foam for support. They also have a Spencore heel plug for shock absorption, and an EVA cushion for added comfort at the forefoot. According to our research, these features make them a good fit for athletes or anyone in high-impact activities needing extra padding.

Custom orthotics can be made from various materials like leather, foam, and rigid plastics, depending on what the individual needs. They're mainly corrective, offering strong arch support, fixing gait issues, or easing foot pain.

User Feedback and Practical Usage

From our data, people generally say good things about the Spenco Polysorb insoles. They praise their cushioning and support, and some folks have found relief from foot pain conditions like plantar fasciitis.

On the flip side, a few people mentioned that the insoles can make shoes feel a bit bulky, and some felt that the newer versions aren’t as durable as the older ones.

Custom orthotics get a lot of praise for precise support and long-term benefits, especially if you have serious foot issues. But getting them customized does come with a cost and often requires a fitting, which isn’t the case with the more readily available Spenco insoles.

Conclusion

If you're looking for moderate support and cushioning for everyday activities or high-impact sports, the Spenco Polysorb insoles are a convenient and fairly affordable option. They’re especially good if you have high arches or need extra shock absorption.

That said, it’s a good idea to try them out in your specific shoes first if you prefer a snug fit or lightweight footwear.

On the other hand, if you have specific orthotic needs due to a medical condition, custom orthotics might be the way to go. They offer personalized support and correction, although they're more of an investment.

In the end, deciding between these insoles and custom orthotics should depend on your individual foot structure, activity level, and budget.
