I feet supinate pretty bad. I have been limping around with feet and back pain for a long time. I did a lot of research and found these shoes! Skeptical at first because I have tried so many insoles, orthotics, cushions and even ankle stabilizer. My next step was to go see a podiatrist to have them make me custom orthotics. I tried these shoes and oh wow, my back pain and feet pain are gone. For supinated feet, adding a small amount of cushion on the heels inside the shoes really help a lot since there is a lot of pressure put on the heels. I do agree with the review that these shoes are not good for running, but a magic for people on their feet walking for long hours. I bought more than one pair because I want to have a spare at all times. Thanks new balance!
