There are too many socks to choose from, and the "hunting socks" I see at wally just ain't cutting it. What type of socks should I get that will help keep my feet warm. Generally I wear a pair of insulated rubber boots, and I hunt in upstate NY so it tends to get chilly now and then.

I was at Gander Mountain the other day and there are a LOT of socks to choose, but what material is best? I've heard wool, but it's hard to find a 100% wool sock. And they would prolly be expensive, are there other alternatives that work just as well and are a little cheaper and don't shrink if you wash them?

Also, how do y'all do it, double socks, or single pair, or what?

Thanks;
