Product description

THE ULTIMATE RUNNING SOCK

A sock that works as hard as you do. Our socks are the most comfortable and durable socks you'll ever own.

1/4 SOCK HEIGHT

Sits just above the ankle. The “just right” height that’s fast and light. Great for low-cut hikers and running shoes.

ULTIMATE COMFORT

No slipping, no bunching, and no blisters. The ultimate fiber for breathability and comfort in all conditions, the All Weather Performance means cool in the summer, warm in the winter.

CUSHION DENSITY

Our lightest sock for race day or anyone looking for a lighter-than-air feel from a tougher than hell sock. Terry loop cushion isolated under the foot for rebound in these incredibly light running socks.

TRUE SEAMLESS

Undetectable seam fusion for an ultra smooth, invisible feel. Darn Tough uses high density knitting techniques, which means there are more stitches per inch. This leads to a more comfortable, durable, great fitting sock with no added bulk.

SUSTAINABILITY

Darn Tough aims to improve the well-being of our community by locally designing and manufacturing the most comfortable, durable, best fitting socks while continuously reducing our environmental impacts.

MATERIALS IN OUR SOCKS

Every material we use in our socks has been carefully chosen and tested to meet our rigorous durability standards. We currently use natural and synthetic fibers, and only 3 types of fiber per sock. As you’d expect, we are actively investigating and testing new fibers and yarn blends that do not appear in our current products. We’ve prioritized Merino wool throughout our product lines and our goal of producing the most responsibly made product is reflected in our commitment to the success of the Responsible Wool Standard.

MERINO WOOL

Merino wool is the most important and relied upon fiber in our products and accounted for 56% of our yarn consumption by weight last year. For many years we’ve prioritized the use of Merino wool exclusively from sheep that have not been exposed to the practice of mulesing. In early 2019 we made a commitment to support the Responsible Wool Standard (RWS) and shift 100% of our wool supply to RWS-certified Merino wool.

RWS is a voluntary standard with strict guidelines to protect animal welfare and adhere to progressive, sustainable farm and land management practices while maintaining traceability throughout the entire supply chain.

Although the market share for RWS is only estimated at ~1% of global wool production, the number of certified sources has grown substantially over the last couple years. Today, 100% of the wool we procure is RWS-certified.

RECYCLED NYLON

We use REPREVE, a nylon 6 fiber made from pre-consumer industrial waste that would otherwise be landfilled or downcycled. Using REPREVE instead of virgin nylon allows us to offset the use of crude oil, benzene, cyclohexane, and other harmful hydrocarbons that are involved in the production of virgin fiber. In short, using recycled nylon conserves energy and water and reduces greenhouse gas emissions from manufacturing. While we aim to reduce our use of virgin nylon in our products, recycled nylon only accounted for 4% of our nylon consumption last year.

We’re actively working with our suppliers to source more recycled nylon so we can incorporate it across our product lines. To date, nylons generated from pre-consumer waste material have held up well against our durability requirements, but we’d like to find an equally good source of post-consumer recycled nylon or yarns that blend both pre and post-consumer nylon.

SPANDEX/ELASTANE

We use Lycra to provide elasticity, strength, and form-fitting comfort. While spandex accounts for no more than 5% of the fiber used in our finished product, it represented 27% of the raw materials we procured last year. Like conventional nylon, spandex is derived from petroleum and has been important to the performance of our products. Unfortunately, it’s the most difficult material in our fiber mix to replace with a recycled alternative.

When it comes to synthetics, we’re primarily focused on converting virgin nylon and polyester to recycled alternatives. However, we’re also looking for functional, recycled spandex alternatives.

SOCK CAPITAL OF THE WORLD

We live and work in Northfield, Vermont. Our backyard is the perfect testing ground to make the finest Premium All Weather Performance Socks. We ski, snowboard, hike, bike and run in the most unforgiving climate in the lower 48. It is under these conditions that we design, test and manufacture our socks.

STILL MADE IN VERMONT, USA

After so many decades why do we still knit every pair of our socks here in Vermont? We don’t do it because it’s the easy thing to do—we do it because it’s the right thing to do. We do it because for us, it’s the only way to do it. There are faster and cheaper alternatives but nobody ever outsourced anything for quality.

• ONE FAMILY - We are family owned. For 40 years we’ve been knitting socks in the Green Mountains
• ONE MISSION - Darn Tough is a family-owned, American manufacturer of end-use-specific socks.
• ONE MILL - Every step of the knitting process happens right here, by us, locally, in Northfield, VT
