I good fit for a foot that wears a size 5 1/2. I have a hard time wearing and looking for a flip flop. That I can wear for a few hours. There work very well. These have very good thick strap. Underneath. It lines with soft fabric. So there is not friction . The wedge is thick and have small support for the arch. ( not much) but it helps with long walks. Cushion seems to last after a few wears. So I'm thinking this shoe will last a long time. Customer service was a awesome, in helping me with my order. ( Thank you ).
The shoe is NOT a dainty flip flop. There are clunky -  I will not wear these  with a sun dress. Only because they are bold and clunky -  not at all  dainty.. So don;t expect this shoe to look delicate. This is a 'working shoe" as far a walking in - very conformable. I like this this wedge. because it works for me
