I'm on my 6th pair of the fitflop THONG sandals.  They are the best sandal for my feet.  I am
a perfect 7 1/2 and buy the 7's. After wearing a year, the stones look spotted, but the comfort
fair outweighs the spots on the stones.  I wear all day long at work in the summer months. The
upper does not stretch out, which is nice.
