I have a problem with overpronation.  The last three years have been a blur of trying different running shoes, hiking shoes, orthotics, etc. Finally I came across these running shoes and I can't believe the difference in how I feel! These are so comfortable that I can leave them on all day. I am able to go back to running on the treadmill with no pain in my feet, knees or hips. I used to have severe lower back pain at the end of the day, but the support in these sneakers have even taken care of that. I really wish I had found these three years earlier and saved myself a lot of pain and money.
