Smartwool Women's Indestructawool™ PhD RUN Light ELITE Micro - White/Grey


Indestructawool™ lands in the run sock and you will not be disappointed. You asked for the ultimate durability.  You wanted extraordinary comfort.  You demanded it be built with the finest fibres.

Well, Smartwool have delivered!  In serious style too.  Introducing the latest PhD iteration with Indestructawool™.

Indestructawool™ is more than a fabric, it's a design system developed so that you will have a sock with greater breathability, longer lasting wear (33% better durability than any PhD sock before it) and miles and miles of comfort.  All to satisfy your epic adventures.

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.  Narrower profile for women's-specific run fit.  That means these socks are not moving any time soon.
  • Ankle band, Upper and Lower instep band, Arch brace.
  • Indestructawool™ Technology 
  • 4 X the durability of any other Smartwool RUN sock 
  • Larger mesh ventilation zones specifically designed for female runners
  • 3D heel pocket to isolate the heel and prevent movement
  • Virtual seamless toe.  Seriously!
  • Light targeted cushioning

Materials - 56% New Zealand Merino Wool, 41% Nylon, 3% Elastane
