Smartwool

Athlete Edition Mountaineer Compression Sock

If you enjoy summiting, spending time above tree line, and prefer any pursuit in the vertical world then the Smartwool PhD Pro Mountaineer Compression Sock should be in your boot. With a compression fit to promote circulation and reduce fatigue, two different elastics to ensure a better fit and shape-holding stretch, and a nearly seamless toe to eliminate blister-causing friction, you'll be able to focus on the climb ahead and not on the state of your feet. Light cushioning provides a plush, comfortable feel all day without adding bulk in your boot, and a more snug fit across your Achilles keeps the sock in place while providing additional support.
