These American Made Pro Weight Solid Color Knit Hockey Socks from Pear Sox offer a great way to look good while staying warm and dry. The 50% Acrylic - 50% Polyester blend creates an excellent combination of durability, moisture-wicking, warmth, and comfort, and of course include an elasticized ankle. The sizes listed are the complete length of the socks from top to bottom, in inches. Measurements should be made from the ankle (top of stake) to mid-thigh to determine the appropriate size.
