I bought this shoe after breaking my ankle as with the swelling and flexibility problems, plus the muscle loss from the cast, I thought it would be helpful.  The shoe has been comfortable, it is more comfortable for me than being barefoot, I hate to take it off!  It is a very casual shoe and looks like a slipper but it is really helping me recover and even after I do I will still be wearing this for walking my dog and around the house, it is so comfortable.  I followed other reader's advice and ordered a slightly larger size, I am normally an 8 or 8.5, the nine fits both feet (the swollen and normal one).  The sole is a comfortable foam, similar to what I stand on the get my balance back in phisio-therapy and it really helps and the rest is lined with soft sheepskin like material that makes it warm and comfortable.  It is a great casual shoe designed for comfort and would also make a wonderful slipper.
