Tough Toe – Dual density toe box reinforced for strength, thinned out to improve boot fit and toe comfort. Warmth without wool – No sheep were sheared for these socks – they breathe, retain warmth and wick sweat better than Mary’s little lamb ever could! Breathe Easy – If your feet stay dry, they stay warm. Mesh top layer helps moisture escape. Shin Bang Buffer – Extra thick panels in the shin and Achilles areas to eliminate bruising and pain from boots with extra room in front of the shins. Commonly referred to as shin bang. Ankle lock – Ribbed channels the above the heel and near the ankle help to lock your foot in place – reducing heel lift in the boot.
