I cant for the life of me remember the name of them, but my uncle bought me two pairs of socks for christmas one year. At first i was like, "Who buys me socks?" But, they're like a synthetic wool or somethin, they go for about $18 a pair, but my feet have never gotten cold with them. I just loosten my laces on stand and im ready. Ill try to find the name of them and repost it.
