This was very uncomfortable to wear from the first time I put them on. I figured ok, let me break in to them (wore them on a park walk). It is killing my feet and legs. I usually like adidas but this shoe was weird: there was alot of space on the toes and when you walk it seems like your feet are about to slip off the shoes from the heel. I took the right size too. I don’t know if it’s the way they designed it but the part where the arch support is, is VERY painful it feels very firm and hurts the muscle on my foot arch which in turn hurts my whole leg and calfs, etc. I wouldn’t recommend this product. Everytime I wear this shoe, my feet and leg hurts for the rest of the night.
