I had a bad sprain last year with 2 surgeries and lengthy recovery.  I was told I could never wear flip flops.  I saw these Orthaheel flip flops in a store, but they didn't have my size.  I ordered from Amazon (of course, they had them).  They came quickly and I was thrilled to start wearing them.  They are stable, thick and force my foot to stay in a good position.  To be honest, my feet get tired after wearing these for many hours (compared to my motion-control sneakers).  But for casual wearing at beach, on the boat, around the house, they work as promised.
