SOCK TECHNOLOGY & INNOVATION

The Smartwool story began over 25 years ago, born out of the desire to ski longer without getting cold toes.  Our founders discovered Merino wool as a performance fabric and became the first outdoor company to make performance Merino wool ski socks.

Since then, Smartwool has continued to invest in technology and innovation to develop the best fitting, most comfortable socks imaginable.  We have developed a sock for every occasion, from our PhD® Pro line to our colourful casual socks.  Because we believe that feet should be comfortable in all walks of life, so you can do more and experience more.

PERFORMANCE SOCKS

PhD® Socks

PhD® socks represent the highest degree of performance, leveraging decades of sock-making expertise. These feature sock technology like our Indestructawool™ innovation, a patent-pending Merino wool-based durability construction, and our 4 Degree™ elite fit system for maximum in-shoe comfort.

Classic Socks

SOCK INNOVATIONS

Indestructawool™ Technology

After two years of designing and testing, we are happy to introduce our toughest socks yet! Our patent-pending Indestructawool™ technology takes premium yarns and knits them in a way that strengthens each aspect of the sock without sacrificing fit or comfort.

Shred Shield™ Technology

Our Shred Shield™ anti-wear technology is featured in all Ultra Light socks and was designed to help our customers go far—and in some cases, extraordinarily far. We worked with ultrarunner Seth Swanson to create a pair of socks that could endure even the toughest challenges. This small innovation significantly increased the durability in the toe area of our Ultra Light socks and allowed him to run over 1000 miles in the same pair of socks.

4-Degree™ Elite Fit

The iconic x-patterned 4 Degree™ elite fit is one of our key sock innovations connecting our activity-specific PhD® socks, from running to skiing, hunting and beyond.  This fit system ensures greater sock stretch and recovery across the top of the foot with a flex zone at the ankle, providing a performance fit, diminishing blisters, and keeping your socks firmly in place.

360-Degree Printing

Our Printed wool crew socks combine our Merino expertise with an updated aesthetic.  We use a   groundbreaking print-on-wool process that supersedes the constraints of knitting and allows for endless design and pattern options.  Now you can express your adventurous side without sacrificing comfort.

Virtually Seamless™ Toe

This knitting feature has allowed us to minimise bulk and blisters and maximise in-shoe comfort so you can ride, hike and run without worrying about your feet.

Activity-Specific Mesh Zones

We have tailored our Mesh ventilation zones for each activity-specific sock.  These ventilation zones were made to expel heat, so your feet stay drier and more comfortable on every adventure.

Tailored Cushioning Options

Whether you like the bare minimum between your feet and shoes or prefer extra warmth and impact protection inside your boots, we have a cushioning level to suit your needs.

Gender-Specific Fit

One size doesn’t fit all when it comes to gender and socks.  Men’s socks are designed for broader feet and deeper heels, while women’s socks are designed for narrower feet and shallower heels.
