The Smartwool PhD Nordic Light Socks combines merino wool, dense toe and heel cushioning, with an improved fit system to give you one of the best nordic socks available. Light half-cushioning in sole protects against blisters and abrasion.

Smartwool socks wicks moisture faster, reduce blisters and keeps your feet at a more comfortable temperature. The natural crimp in Smartwool fibers trap air pockets within the fabric, keeping your feet warmer in the winter and cooler in the summer. The natural fiber also greatly reduces bacteria growth and odor build up.

Smartwool's slogan for the PhD sock line is "The Highest Degree in Performance". Smartwool used paper-thin force sensors to measure the pressures athletes' feet endured as they pursued their sports. Then they fine tuned the socks to provide ultra-dense cushioning in the areas where impact was highest and stripped away the cushion that wasn't needed. Smartwool evaluated the mechanics of the athlete's foot and identified critical fit areas so that maximum fit, protection, and minimum weight were achieved.
