I was over pronating while walking in my hoka clifton 10's and had so much foot pain. I could not make it past 3 miles of walking without heel pain & pinky toe(bunionette)pain in one foot, and arch pain in the other. my feet were throbbing after every walk. I didn't want to spend extra money buying a new pair of support shoes. I bought these and now have ZERO foot pain, they are amazing. I can walk 3 miles and it will feel like nothing. They are true to size, fit in my cliftons well and have a nice firm arch that doesn't flatten when you step on them.
