I broke both my ankles in an accident and this product was recommended to me for two separate issues. On the one hand I have to protect the healed but sensitive surgical incision with an air splint. On the other hand, I have an avulsion fracture (a broken end of a bone) that hopefully won't need surgery. The area where the bone fragment lies must be padded under a cast or shoes. This product is a champion in both situations. The only problem I have is that my feet are swollen and after a few hours they dent badly. This will correct itself over time and is not a product defect. The only suggestion I could give is that maybe the material could be a bit more stretchy. Another note: they come in a 2-pack. At my doctor's, a single sock costs $30. You can get two for $11 or $12. Much better.
