I had foot surgery in January and the doctor said I would have swelling for about a year. I bought these because the advise my Podiatrist gave me was "wear crocs". I can wear the shoe on my recovering foot and it does not get tight even with the swelling. The other shoe never slips on my good foot. They are not the most stylish of shoes but they get the job done. I wear them to work 5 days a week and because I never go barefoot at home, I need to buy a couple more. I think I'll do that right now....
