I now own two pair of these shoes.  At first they are very difficult to put on, like putting gloves on somebody else.  But then they feel great.  I can move my toes all over and flex my foot in any direction - not possible in most shoes.  I can even spread my toes.

They are a little awkward to walk in initially.  I'm used to shoes with even a little bit of heel; these have none.  The bottoms are thin but comfortable.  You can feel the surface you're walking on, but the bottoms are dense enough to cushion my soles from the sharpest, most uncomfortable rocks.  They take a little getting used to but quickly become extremely comfortable.

My only complaint is that the shoes are a little too long and the toes a little too short.  Because of the neoprene material, they fit pretty well, despite being almost an inch too long. I tried a smaller size but the toes were too tight.

The hardest thing about wearing them is that they are so odd looking that they seem to cause commotion where ever I wear them.  My mother-in-law's eye doctor and staff took pictures of them!
