SmartWool absorbs moisture from the skin into thousands of micro-porous cells where it is broken down into vapor and evaporated. These air pockets create an insulation layer that can block out cold or heat, leaving a dry layer of air next to the skin.
Nothing insulates better than dry air.
This extra length creates a knitted yarn that is itch-free and silky soft to the touch. Because of SmartWool socks' ability to control and evaporate moisture, they inhibit foot fungus and offensive odors. This results in reduced shock and superior cushioning that maintains its natural shape for many years, unlike socks made of lesser quality wool. The evaporative and cushioning properties of SmartWool provide for excellent blister control. Guarantee Guaranteed not to itch , shrink or loose their shape and to outperform all other socks or your money back.
