DARCO OrthoWedge, Size: Approximately 24cm These sandals are designed to prevent weight from being placed on the toes. I used them for about two months after toe surgery for going outside. However, I didn't go out often, and the distances I walked were short. There is one scuff on the strap, but it's not noticeable and doesn't affect use. I bought another pair of the same sandals for indoor use and wore them separately. They can be used on either foot. They are shown in the last photo. The other pair has already been sold. This is one of the pairs that was used outdoors.
