An A+ goes to the Wigwam wool blend snow socks. And they are made in the USA!! These socks are pretty great. They aren't 100% wool, like I wanted to buy, but I think the nylon in them actually helps wick sweat off my feet and ankles. This is especially important with insulated and waterproof boots...because otherwise they trap in the moisture! If you have sweaty feet like me but still want your toes to be warm when you're outside doing winter work, these socks will do the trick.
Plus, they're made in the good old USA which is something I look for in my clothing. A win-win, especially for this price.
