SmartWool Adrenaline 3/4 Crew Sock

A 3/4 crew height outdoor sock (1 1/2” lower than standard crew) that provides minimal bulk under training tights and works well with today’s lower cut outdoor/trail shoes. The Smartwool Adrenaline 3/4 crew features a 1/2 cushion sole: high density padding that runs under the sole and up the Achilles tendon area providing maximum protection where most needed. Smartwool's Smart Fit System provides a great fit no matter what the conditions.
