The first circular sock: Made From Worn Socks
ISPO Award Winner 2023: Smartwool Second Cut Hike Socks
Smartwool Second Cut Hike Socks are created using recycled yarn made from old socks. Yet, they offer the performance of a brand-new sock made from virgin material and set an example against waste and landfill in the outdoor fashion industry.
In 1994 Smartwool invented their first-ever Merino wool performance sock, the Classic Hike. Now, that sock comes full circle with The Second Cut™ Hike sock. It combines the iconic fit and feel of the original sock with a circular yarn utilized from the brand’s sock take-back program. In surveying their customers, the brand found, that there is a need for a recycling program for socks. Hence, the brand invested in finding a solution, rather than downcycling collected textiles at the end of their lifecycle. While the brand started out by creating a dog cushion from the material they collected and kept out of the landfill, Smartwool has now managed to create new socks out of old socks.
The Second Cut™ Hike Socks are the manufacturer’s first circular socks, made with repurposed yarn from Smartwool's Second Cut™ sock take-back program. Here, the brand cooperates with the circularity manufacturing facility, Material Return.
An attempt at closing the loop and keeping material from old socks in the production cycle is not only a push to not waste resources but also to address the fashion industry’s waste problem. With only 12% of clothing materials recycled globally, socks are one of the most thrown-away pieces of apparel. The Second Cut project highlights not only a really innovative concept but also Smartwool's shift toward a circular business model, which involves collecting and repurposing materials for deconstruction and reuse. »With the relaunch of our Second Cut Project, we are one step closer towards achieving our 100% circularity pledge by 2030,« said Alicia Chin, Sustainability & Social Impact Director, Smartwool.
"We are committed to finding innovative ways of manufacturing to limit our impact on the environment, and the Second Cut Project allows consumers to aid in our progress by visiting our retail partners to recycle their socks," Alicia Chin explains.
The project includes customers in the take-back program and caters to their need for involvement as well as a more eco-friendly option when buying new outdoor socks. In addressing textile waste and educating customers, consumers also end up empowered and engaged to be part of the solution. The Second Cut Project and socks show that brands and consumers can – and should – work together to reduce environmental impact.
The wool used in the socks is responsibly sourced, ZQ-certified merino wool. The rest of the fiber comes from 2nd cut material/sock waste. For this, worn-through socks that would usually end up in landfill, are collected and then ground up into shoddy. From there, shoddy is blended with merino wool and spun into yarn. Designed with an elastic arch and a seamless toe for more comfort, the same performance as using virgin materials is achieved.
The take-back program involves both consumers as well as participating retail partners: Kicked off in retail, consumers can give back their worn socks there. Participants can also send in old socks for recycling by selecting a free mail-in bag on Smartwool.com. All brands, sizes, colours, and materials of unwanted socks are welcome. They should be single socks, so not rolled up or paired. Smartwool has collected over 1 million socks and counting to keep good materials out of landfills and give old products new life.
