"First off, these run on the small and narrow side, so if you do purchase these, size up. I sometimes wear a 9 if the shoe runs small, and a 9 (39 in this shoe) was still too short for my foot. Also, the sole is very narrow from the mid-foot to the heel. Of course, they are flip flops, so don't expect much support or stability. That being said, the quality is not at all what I expected. They are leather, but the straps are flimsy and cheap looking. The bottom is also very stiff and feels lumpy under foot. Bummer."
