Though a rocker sole, not your usual. Worth every penny an MBT costs. Immediately my back felt better, but I have found they took getting used to as far as the ankle and the foot are concerned. I liked this sandal so well that I ordered a second pair in another color. Now I wear one pair or the other for several hours each day. I like the sandal but found that MBT also makes several closed toe shoes for men as well as women.
