Great socks

I finally found the sock I was looking for. They fit me and are the weight I need ... plus, they keep my ankles warm. Super wonderful.

Just the thing

I replace a pair of these every year. They reliably keep out the chill when it's not too cold out, and they're a good base under a heavier mitten when it's actually cold. I tend to wear them through a lot of the fall and spring, too.
