A do everything sock, the SmartWool Adrenaline Light Mini Crew feels right at home in a pair of running shoes, mountain biking shoes, or light hiking shoes. The SmartWool signature fitted toe and heel caress the foot while arch and ankle braces hug their target areas, creating a sock that stays in place throughout a busy day. The SmartWool Adrenaline Light Mini Crew sock also features the ultra soft SmartWool fibers, known for their ability to wick moisture extremely fast. The result, a sock that keeps your feet dry when pushing through a half marathon in mid-summer heat and warm when out for a ride on a cold December morning.
