Summary: Best ever.
Comment: I've used inserts in the past, but none as comfortable as these. And I've had none of the problems some of the other reviewers described. I found heating them straightforward and easy, as was inserting them into my shoe, no noticeable shrinkage, no squeaking. They do add some weight to your shoe, but unless you're a runner, I can't see that it would make any difference whatsoever. I have nothing negative to say about them at all. They add comfort, and reduced the pain I've been experiencing.

Summary: Devent insole
Comment: This insole works fairly well and can be heated/molded to your foot. However, I am undecided if it really helped my high arches or not.

Summary: The best insole I ever tried
Comment: For me this sole worked best with a boot, its perfect - no questions about it.
I still have to try it with soft sports shoe, I am going to order few more.
There must be other great insoles out there but this is the best out of the once I tried.

Summary: Squeek Squeek
Comment: These are WONDERFUL support footbeds only ONE problem... they SQUEEL when you walk. They need to be trimmed with duct tape and so does the inside of the shoe where they rub then they are quiet as a mouse. I am surprised Spenco doesn't address this problem. I'm sure it would be an easy fix by using a different material to finish off the footbed. I LOVE the support they give so I work with the "problem". I highly recommend these to anyone who needs orthotics. They do the same thing at a fraction of the price so you can afford to have them in ALL your shoes.

Summary: heavy and affects shoe fit
Comment: I have a slight problem with pronation of my right foot, and didn't want to spend hundreds of dollars on custom orthotics, so for $30 I thought I would give these insoles a try. They promised both comfort and support, and the guy in the advertisement looks just like I would like to (if I was 20 years younger and 30 pounds lighter....) Fitting them into my shoes (Asics Gel Keyano) was a bit cumbersome (heat in oven at 200 degrees for 3 minutes, garnish lightly with cilantro, etc). Turns out the right insole didn't go in as far as the left, leading to a bit of a 'hump' sensation in the middle of my right foot. Talk about your arch support. The first time I ran with the Polysorbs, I immediately noted that both shoes fit a lot tighter. There's only so much volume in a shoe, and the Polysorb insoles take up a lot more space than the insoles the shoes came with. A related problem was the weight. Granted, they're not made of lead, but still the Polysorbs weigh more than the insoles they replaced. I have certain routes and routines (hill sprints, etc) that I run regularly, and I noted that I am definitely slower with the Polysorbs, and my legs are more tired. On the other hand, my knee didn't hurt at the end of a run as it often does.
Bottom line from my experience - the Polysorbs seem to provide extra cushioning and support, as promised, but it comes at a price of heavier shoes and slower times. Also, consider sizing up one half size to allow for their impact on fit.
