I have a pair of insulated hodgmans and i wear a pair of thin blue polyester (its not polyester but it feels like it) type socks and a pair of wigwam outlast wool socks. the polyester type socks wick the sweat away from your feet into the wool socks keeping your feet dry. also when im not wearing rubber boots, i have a pair of rocky gore tex socks that i wear that not only keep my feet dry but do better at keeping them warm than wool socks, however, i wouldn't wear them in a non breatheable rubber boot because it would be like a sauna leaving your socks miserable
