Socks can be made with a variety of yarn styles, but sport weight and cotton or wool blends are best. For winter socks, if you live in an extremely cold climate, the warmth of the socks will make a big difference while outdoors for long periods of time. Measurements (with measuring tape or ruler) will be required, not your shoe size. Length of foot from heel to toe, and width of foot if extra wide or small feet. Width of calf also needed if extra wide or small.
