Since the inner sole has a thickness, at the beginning of use, there is a feeling of pressure on the toes and it also involves some pain. I think that it is much better than the one of the \ 100 shop I used before. I feel that I have become familiar with my feet when I used it for about 10 days. Since it is standing work, it tends to put weight on the heel, but the air cushion inside the insole supports the heel gently and no longer feels pain as before. Although it costs a little, I think that it is quite good insole.
