M.R.
My cousin is a physical therapist and says no one should wear crocs, ever! Same thing with my MIL's physical therapist who did therapy on my MIL for a ruptured achilles tendon. She made my MIL promise she would throw out her crocs. From what I have heard, the support is not there, and they slip and slid around. I second the merrel, slip on moccasin type shoes.
