This seemed like a great sock so I spent about 30 bucks for 8 pair. I do a ton of walking so a comfortable sock is of paramount importance to me. After regular use and repeated proper washing these socks bind your ankle. This is due to a design defect. Apparently the manufacturer folds over about 1.5 inches of the top of the sock inside the sock and then adds a stitch line. This stitch line is a source of irritation after a few hours of wearing. I called the company and basically they said tough, that's the way we make them and others haven't complained. I pointed out that 99.9% of the buyers probably just discard the sock packaging and don't remember who to contact. Anyway their customer service sux too. DON'T BUY THESE. You can do better.
