Great buy, the top portion of the sandals are not as comfortable as the foot section. I went up a half size to a size 7 and they fit more like a 6.5 this is due to the heel strap that is not adjustable. I had to return one pair and requested a replacement pair with no problems from the seller, they mail the shoes out immediately and gave me ample time to return the pair that was replaced. I would highly recommend this seller.
