Review (5/5): Ran the Chicago Marathon in them!
I was having trouble with foot pain while running and had been in PT for 18 months after a serious injury to my leg which prevented me from walking. After recovering and spending many months training, this foot pain re-cropped up. My PT gave me exercises but I was seriously concerned about having pain on the course and not being able to finish. I bought this and 3 other things. I tried them out literally the week of the race and figured I could just throw it away on the course if it didn't help or harmed me in some way. IT WAS AMAZING. I had no pain, it didn't rub, and bothered me in no way for the entire 26.2 miles, even though I broke the cardinal rule and "tried something different" right before the race. I ended up using them again on a backpacking trip through europe in some boots that didn't have much support and again, they were great. I have high arches that collapse when I bare weight, and it works for me too, it's not just for flat feet or plantar. Super happy!
