This is the third pair of Reef Leather Fanning sandals I've purchased after purchasing two non-leather Fanning sandals as these are the only flip flops that fit me and don't fall off when I walk and are extremely comfortable. I was a bit disappointed in this latest pair as Reef has substituted the soft grain leather on the underside of the uppers for a knit fabric which is not nearly as comfortable and I am concerned about how well it will wear.
