My wife said that if the sandal was a perfect it would have been an extremely comfortable shoe.  However, it did not. She normally wears 9M in almost any shoe/sandal/boot, but when out of stock, she orders an 8.5 W with no problem.  Unfortunately, that was not the case here...the sandal was unusually long for an 8.5 size shoe with nearly a half inch showing from her heel to the back end of the sandal (looks like a 9.5 size in the length from toe to heel). Doubly unfortunate, the shoe was not an Amazon Prime buy (our bad) and now she will have to sell them to someone because the seller wants a 10% restocking fee and we have to pay the return shipping.  Moral of this story...buyer beware!
