Allbirds, which reports quarterly and year-end results today, has started a new resale platform in conjunction with Trove, a market leader in branded recommerce. Called Allbirds ReRun, the platform will offer customers at Allbirds stores in Los Angeles, Chicago, and New York City the option to trade in their Allbirds footwear for a $20 store credit. The program is expected to expand to other U.S. retail locations in the future. Through the ReRun platform, consumers will have the ability to purchase slightly imperfect and gently used shoes at reduced prices, starting at $59.

The new recommerce program ties in with Allbirds’ Flight Plan, a series of sustainability commitments that include reducing the brand’s per-product carbon footprint by half by the end of 2025 and cutting it to near zero by the end of 2030. The recommerce partnership with Trove is designed to prolong the life of products, which is a component of Allbirds’ sustainability strategy. Allbirds is already a 100% carbon-neutral business through the use of third-party verified carbon offsets.

“To create a more sustainable fashion economy, it’s crucial that we take a holistic approach,” said Hana Kajimura, Head of Sustainability at Allbirds. “By launching our trade-in program, ReRun, we will enable our customers to play an integral role in extending the life of our shoes.”
