I bought this sandal in the 39 M because that size fits well on me.  This sandal fits like it is a part of my foot and is very comfortable.  The foot pad is soft and has good arch support, but what I love most is that the inside of the leather top is nice and soft and doesn't cut into my toes.  I think I will wear these for a number of years since it looks like they can be resoled and reheeled.  I'm looking for a cream to protect the sand-colored leather.
