Sock Architecture

Smartwool socks architecture

PERFORMANCE: Smartwool’s Performance socks represent the highest degree of performance, leveraging decades of sock-making expertise. These feature additional technologies like lndestructawool'" technology, a patent-pending Merino wool-based durability construction, and our 4 Degree'" elite fit system for maximum in-shoe comfort. Athletes who require a higher level of comfort, fit, and durability choose the performance Smartwool socks.

CLASSIC EDITION: Over 25 years ago, Smartwool introduced Merino wool socks and forever changed how outdoor enthusiasts look at their feet. The Classic Hike sock is one of the best-selling apparel items in the outdoor industry and the starting point for relentless innovation in comfort and performance. The Classic Edition is for outdoor enthusiasts looking for the most comfortable sock for all their outdoor activities.

EVERYDAY: The Everyday collection is the foundation of Smartwool's versatile 'wear everywhere’ socks. They combine the performance and feel of Merino wool with comfort-focused features and everyday style to create a better overall unisex sock. The everyday range is perfect for people looking for exceptional comfort and style for everyday life.

Sock Technology

Let’s look closer at the tech that goes in to Smartwool socks.

smartwool socks technology

- 4 Degree™ Elite Fit system

Smartwool's most advanced proprietary fit system is found in all of their Performance socks. This locked-in, secure-fit platform ensures less slippage and more summits - helping to keep your sock in place for better flex and recovery.

- lndestructawool™ Technology

This isn't just something Smartwool added to their Performance socks, but a different way to build them. lndestructawool technology is a process that places the right materials in the right places to create a stronger, nylon-reinforced exterior while keeping Merino next to skin.

- Shred Shield™ Technology

Shred Shield technology reinforces the toe cap with minimal cushioning, to combat excess friction from the top and front of toenails. It increases durability by 3x and is found in all of our zero cushion, 200-needle Performance and Everyday socks.

- Made in the U.S.A.

Every single pair of socks we make is proudly produced in the U.S.A. from imported yarn.

- Recycled Nylon

As part of our ongoing sustainability efforts, Smartwool is using recycled nylon in all their Performance socks to cut down on environmental impact without sacrificing performance. When they add other materials to their Merino wool, they want to do it as responsibly as possible. Well done, Smartwool!

- Virtually Seamless™ Toe

Smartwool have smoothed out the toe seams for ultimate in-shoe fit and comfort. This technology is found in Performance and Everyday socks.

- ZQ Merino™

Smartwool partner with the New Zealand Merino Company-which developed ZQ-certified wool to ensure the wool they use has the highest standards of environmental, social, and economic sustainability while safeguarding animal welfare.

- Women's Specific Fit

Women's feet are like a slice of pizza, and men's feet are like 2x4s. They need different cuts of socks. Smartwool's industry-leading women's specific fit is crafted to provide more comfort and performance for women, with its narrower fit and shallower heel.

- Extra Stretch Calf

Smartwool have engineered extra stretch in the leg of their socks to accommodate wider calves. This feature will provide greater stretch around the calf of the sock to deliver more comfort without sacrificing a stay-in-place fit.

Wow, that's a lot of tech and details!
