Works better than expected

After trying multiple insoles for sore feet and heels aching from my foot drop, these insoles have actually helped. I work on my feet all day and have only found two insoles that help my feet and these are one of them. They cup my heel and help with the impact as I walk. I will definitely be ordering more of these for my everyday tennis shoes as well.

So far, great product. Arrived quickly, there appears to be a break-in period as stated on the product page. Heel cup is the best of any I've used.
