An updated and improved version of an old favorite, this was one of the first socks we ever offered to our customers nearly two decades ago. So many people asked for them, that we felt we had to bring them back . . .with some improvements of course! We've added a little length to them so the come up slightly further on the calf. The top is ribbed now and there is more elastic and nylon so they stay up better. Because they are double knitted, it is actually a sock knitted inside a sock so you are wearing two alpaca socks at once! If you are looking for a way to keep your feet warm this winter, you've found the right sock. They are often worn as slipper socks keeping feet warm even on the coldest of floors and in the draftiest of rooms. They are totally reversible as well. Want a black sock - you've got it. Need a fawn one, well, you've got a pair of those too - just turn them inside out. The picture shown is one pair of socks! Warm and wonderful socks that have many repeat customers over the years.
