Smartwool PhD Run Ultra Light Micro Socks

When it comes to running socks, we pull out all the stops to keep making improvements on our products. With brand-new Shred Shield technology to help improve wear in the toe box, our PhD Run Ultra Light Micro socks feature the 4 Degree elite fit system and our Indestructawool technology for a dialed-in fit and improved durability.

Engineered with Smartwool's new Indestructawool technology, the PhD Run Ultra Light Micro Socks feature a patent-pending construction method providing merino-based durability. The improved abrasion resistant construction of the socks increase durability and comfort for long-lasting performance. A 4-degree elite fit system used two elastics in the construction for greater stretch and recovery to ensure the sock is kept in place. The virtually seamless toe construction eradicating uncomfortable rubbing and chafing from seams for enhanced comfort, whilst the shred shield technology increases durability preventing wear and tear from the toes. Mesh ventilation zones provide exceptional moisture management properties wicking sweat and moisture away from the skin for damp-free comfort, whilst cool air is encouraged to circulate to remove uncomfortable heat build-up providing maximum breathability to keep you cool. Finished with an Achilles tab designed to prevent the sock from slipping into your running shoe, these Smartwool PhD Run Ultra Light Micro Socks work hard to keep you pushing yourself to new limits.
