Will be buying more of these for the remaining clamps on my Thule bike carrier. I have another pair of Chacos and was so excited about this one. I think this is more of an intimate devide than actual workout tools. Although Im a 6 tall, size 12 woman, the XL was a little large but very stretchy. The buckle that anchors the shoe was a little finicky to get situated, but overall, the shoes are nice. The material is real calf hair. I was concerned that the V front would allow my foot to slide forward too much. I received this product with high hopes even after reading some unsatisfactory reviews from others. I need a 13 in the Duet Sport. THE WH1000M3 are very quite with NC and the controls not the side of the Headphones are outstanding way to go Sony.
