PhD Sock Updates

  1. NEW SOCK WELT - Uses wider elastic at the sock opening to help keep the sock up without cutting into the leg.
  2. NEW ELASTIC ARCH - Increased power of the elastic around the foot arch area enables a more locked-in fit.

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.

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

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.
