The WIDE sock was developed for people wanting a non binding sock with no elastic. This sock provides just that while still providing the benefits of the Double Layer. The sock is designed with no elastic for a wider, more comfortable top and with no heel to make it easy to get on and off. The construction is still two layers which absorb friction with the slight movement. Feet stay dry as the CoolMax wicks the moisture away from the foot and into the outer layer for evaporation. This sock is also available with a black outer layer to allow use with casual dress while still maintaing the healthy benefits of the white inner layer. Fabric: Inner Layer 70% CoolMax®, 30% Nylon Outer Layer 68% Merino Wool, 24%Nylon, 4% Lycra®
