Our Hi Volume Socks are designed with our highest weight for the most warmth. Great for rental boots, pack boots, & any loose fitting molded or soft-shell boots.

Features

• Air channels or the 'moisture transfer chimney' run along the outside of the sock to allow vapor to escape and provide excellent moisture movement
• Looped back heel & toe cushioning add some extra cushioning and advanced fit
• Motion control arch support band and articulated foot breaks also help reduce bulk.
