I go through black socks like my wife goes through Girl Scout Thin Mint cookies, which is to say, extremely fast. And over time, I've become something of a black sock snob. When it was time to look for my next batch, I naturally went to Amazon first, and was impressed by how many folks loved this product, so I gave them a try. Well, you've made a believer out of me, too! These socks are extremely comfortable right out of the package-- not too tight around the calf like some, and not droopy like others. The reinforcement in the toe, heel and bottom is reassuring, too. In fact, as soon as I'm done with this review, I'm going to order two more packs!
