Smartwool PhD RUN Light ELITE Micro - Black

Just when you thought a RUN sock was the best it can be, along come the wizards from Smartwool.  This fresh new take on the PhD RUN sock is even more technical, has 4 x the durability of the old one, sports virtual toe-seams and has targeted gender specific ventilation zones.

The elite range of the new RUN socks have targeted micro padding where runners need it the most - the ball and heel of the foot.  200 needle point construction provides high density with minimal weight.

Check this out:

  • Improved 4 Degree Elite Fit System that uses two elastics in construction for greater stretch and recovery.  That means these socks are not moving any time soon.
  • Ankle band, Upper and Lower instep band, Arch brace.
  • ReliaWool Technology in high impact areas provides longer lasting protection and comfort.
  • 4 X the durability of any other Smartwool RUN sock 
  • Larger mesh ventilation zones specifically designed for male runners
  • 3D heel pocket to isolate the heel and prevent movement
  • Virtual seamless toe.  Seriously!
  • Light targeted cushioning

Materials - 51% New Zealand Merino Wool, 46% Nylon, 3% Elastane
