These Canadian-made winter socks are ideal for the coldest days; and they fit well, too, with smooth toe seams that dramatically increase wearing comfort over long periods. The secret to their warmth-enhancing qualities has to do with very tightly knitted pile--this lofty weave holds more air near the skin, which in turn insulates your feet very effectively when they need it most. And the fact that these socks are essentially made from soft wool is a definite improvement over the many synthetics available from other manufacturers. Canadians know how to protect themselves from the cold. Buying these excellent J.B. Field Icelandic socks is the logical purchase equivalent to acquiring an English umbrella!
