Little feet can get tired on big Hikes. The Kids Hiking Pro Classic Cut Sock take the strain off the foot with a combination of spacer pads and ventilation zones. As a result, lengthy walks are just child's play. Jack Wolfskin have incorporated a special mesh fabric on the heel of the sock to let in fresh air and help keep the foot cool. The socks also give those little feet more support above the ankle, preventing chafing, and cushioning against bumps and knocks.
