Technical Info

Pro Ski Racer Upgrades

  1. Shin cushioning designed to help relieve ski boot top pressure without taking away from precise lower leg fit.
  2. Shred Shield™ durability technology helps reduce wear from toes and adds extra warmth.
  3. Increased power of the elastic around the foot arch area gives a more locked-in fit and helps provide a better “ski feel.”
  4. Uses a wider elastic at the sock opening with more stretch and recovery to help keep the sock up.
  5. New open mesh pattern on the top of the foot helps increase blood flow to keep toes warm.

  • 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.
