Press Release / 19.07.2018


Smartwool has spent over two decades designing, testing, and refining the activity-specific innovations and technologies incorporated into each pair of Smartwool PhD® socks, in order to amplify connection to the trail, slope, and road - providing pure comfort and confidence for a life lived outdoors. 'Go Far, Feel Good'.

Smartwool PhD® socks feature:
• Indestructawool™ technology
• 4 Degree™ Elite Fit
• Virtually Seamless™ Toe
• Women's Specific Fit
• Activity-specific mesh zones
• Dialed-in Cushioning
• ZQ-Certified Merino Wool

Indestructawool™ Technology
Smartwool's new, patent-pending Indestructawool™ technology isn’t just something added to their performance socks, but a whole new way to build them. Smartwool developed a new, much more durable knitting technique that enables 30% more choss-filled approaches, gut-wrenching descents, and paradigm-shifting summits.
4 Degree™ Elite Fit
X MARKS THE SPOT. The iconic x-patterned 4 Degree™ elite fit is one of Smartwool's key technologies. It unites all activity-specific Smartwool® PhD® socks from cycle to mountaineer and beyond. Locked-in, blister-repellent, ready-to-go platform that enables less slippage and more summits. This helps to not only go far, but to go fast, go freely, and go ferociously!

ZQ-Certified Merino Wool
After 25 years, Merino wool is still Smartwool's secret sauce. It helps regulate body temperature, moves moisture away from your skin at a vapor level, and resists odors. The PhD® socks use higher-quality, finer Merino wool in order to further increase durability and softness.

The ZQ Difference
Happy sheep grow better wool ZQ-certified wool is a New Zealand program that ensures the highest-quality fibers while elevating animal welfare, environmental care, and social sustainability.
