Music sounds great too. Caveat emptor. The fit is a bit larger than my actual shoe size in width especially. They cost more than other reefs, but I think they are worth it. I would say the size guide given here is correct. I expect them to last at least five to six months, usually with only a little wearing down. This was just what I was looking for. Ever since Ive purchased my first Anker Cable from Amazon, Ive never bought anything else. For anyone suffering from dry, sensitive skin. And thick cushiony sole.
