These are a super comfortable pair of summer sandals by VIONIC in a size 7 wide. The straps appear to be either leather or suede, but there is nothing on the label that indicates the materials. At any rate, they are very soft feeling. The top strap is adjustable with Velcro. The bottom strap has a buckle. The pattern on the straps reminds me of cork, with small gold flecks embedded in it. I may have worn them half a dozen times, if that. Very versatile.
