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.
