Because two pairs of socks is better than one: Opt for the Casual Sock 2-Pack. These everyday athletic socks with low-key, flat-knit Atomic branding are made from a soft yarn with subtle cushioning in the toe and heel. A seamless toe box eliminates friction and pressure points from the front of your foot. Anatomic foot shape and left and right foot labeling on each sock means you get a perfect fit for each foot. The sock is made from 60 percent cotton, 38 percent nylon, and 2 percent elastane for stretch.
