I work long hours in the restaurant as a server. These shoes have memory foam only in the heel, and then it drops off for the rest of the foot, causing pain in the middle of my feet. Disappointed. I paid more money than I ever have thinking my feet would thank me. They were also a bit smaller than usual. I wear a 7.5 in a sketcher sneaker so was hoping these would fit the same. Tried the 8, and they were too big, just slipped off at the heel.
