PhD Sock Innovation

The performance enhancing benefits of Merino wool helps regulate your body's core temperature reducing lactic acid build-up and helps stabilize your heart rate.

4 Degree™ Elite Fit System

The new 4-Degree Elite Fit means that your foot gets extra-special attention in your ankle, arch, and all along your instep.


By putting more Merino wool in high-impact and high wear areas, we help reduce shock and abrasion while giving you longer lasting wool benefits.

Mesh Venting

Women's-specific mesh ventilation zones provide additional breathability and moisture management

Ultra Light Cushion

Non-cushioned sole and leg for a close fit in tight-fitting performance boots

Merino Wool Benefits

Smartwool combines the function of wool's natural strong suits with their one-of-a-kind knitting technology to give you:

  • Temperature control, so you're warm when it's cold and cool when it's warm.
  • No Stink, because Smartwool's Merino wool keeps your feet dry and is inhospitable to bacteria.
  • Easy care, which means that you can machine wash and dry.
  • Ultimate breathability.
