Great foot support!

I took a risk years ago ordering these inserts online. So glad I did. They have been awesome for my feet.

Better than prescription

I paid $ 300 for prescription insoles that squeak bad even after scuffing them and applying baby powder. The tops make my feet sweat and burn. They are very uncomfortable. The Protalus insoles feel much better to the bottoms of my feet. I have even started walking for exercise again. They squeak a little but not as bad. I'm able to walk further with less pain. Just wish they were at a lower price.

First Time

Did a 10 miler yesterday with these and found the least amount of discomfort of any inserts that I've used. Will be using
