Sock Geek Says:

Two-layer construction under the ball and sides of the foot reduce the probability of unwanted blisters. Low friction construction reduces abrasion over the heel and toes. Lightweight construction brings a snug fit with less bulk. Dri-FIT fabric pulls away sweat to help keep you cool and comfortable. Ventilation holes allow greater air circulation for cool comfort. Reinforced heel and toe for enhanced durability. Left/Right specific fit for maximum comfort and performance.
