Yeah compared to a full setup snowboard socks really aren't that expensive. Maybe I skimmed over this too fast but use one pair, don't double up. Many will seem too thin to keep your feet toasty, but remember there's a bunch of effort going in to these to make the rider more comfortable. There is such a thing as a really thin wicking sock, but most snowboarding socks these days have wicking fabric that really helps, and your pets at the house will thank you when you take them off
I picked these up at a preseason sale last year for 12 bucks, but have a pair of smartwool too and would recommend either.
