Abstract
A sock which comprises an outer shell made up of an arrangement of non-stretchable fabric combined with a panel or panels of stretch fabric and an inner shell of insulating material. The fabrics are lined with a waterproof, breathable liner, such as Gortex or the like. The inner shell is connected with the outer shell only at the open upper end of each. A "stretch" or elastomeric cuff is connected to the open and serves to hold the sock up on the ankle and to prevent loss of heat or entry of water should the leg be immersed above the ankle.
