I have medical issues with one leg, very bad swelling due to an accident. I have a very difficult time finding a shoe that works with both feet. These are perfect. The straps are long enough from this manufacturer that I can let out the left foot to accommodate the swelling that increases during the day, while being tight enough to comfortably fit my right foot. They are a bit firmer than another brand I’ve bought, which I prefer in a shoe that I want to wear outside the house. Iv’e worn them for a couple of weeks now, both with and without a compression stocking. Very pleased. If they continue to hold up to daily wear (some reviewers have had issues with the buckle breaking) I will definitely be buying more. Regarding sizing, I am a USA 8.5 and I bought up, a 9. However if it wasn’t for my problem foot, I think buying down to an 8 would have been better. I tried to show in one photo how much space I had at the heel.
