This Sock Brand Is Going Hard on Responsible Fibers

With its newest launch, Swiftwick has achieved its 2023 goal of including recycled, renewable or responsible fibers across all product lines.

The Tennessee-based sockmaker has announced the release of the Maxus performance sock, which features a Repreve recycled polyester footbed, providing plush comfort and moisture-wicking capabilities. Each pair of socks contains the equivalent of one post-consumer water bottle diverted the ocean or a landfill.

“Sustainability across both our business practices and our finished goods is important to our company and top of mind for our customers, which is why we’re excited to share the new Maxus made with Repreve,” Swiftwick chief marketing officer Joanna Mariani said. “We continuously work to reduce our environmental impact across our manufacturing processes, and this new release helps to close the gap in our sustainable product offerings.”

Meanwhile, Repreve maker Unifi last week reiterated its commitment to diverting 50 billion plastic bottles from landfills and waterways by 2025. It surpassed its 2022 goal by 5 billion bottles, bringing its total conversion count to 35 billion to date.

Each sock contains one post-consumer plastic bottle's worth of recycled content.

In addition to incorporating recycled polyester into its line, Swiftwick has also committed to sourcing 80 percent of its raw Merino wool from Responsible Wool Standard-certified (RWS) sources by the end of 2024, with an ultimate goal of reaching 100 by 2027, she said.

RWS works to ensure the welfare of the animals and the land they graze on, while certifying animal husbandry and land management practices in the realm of wool production. It also traces certified wool from the farm through the end product.

In other sustainability developments, Swiftwick removed single-use plastics from its packaging in 2019.
