Sanuk, a division of Deckers Brands, has announced the second generation of its SustainaSole footwear collection, which it calls its “most ecological innovation” since its debut in July 2020. The second collection includes the two vegan slippers Donna (women) and Skuner (men) and is comprised of 55 percent total recycled material by weight. Thanks to a renewed collaboration with Blumaka, a California-based manucturer of recycled foam products, foam waste was again used to produce a cushy, durable filler for shoe soles. The textile upper is made from 100 percent recycled GRS-certified fibers, including recycled PET fibers, recycled cotton fibers and recycled polyester fibers. New is the undyed upper of the new shoe models. According to the brand, this has saved more than 200,000 gallons of water in total in production. The two new models are machine washable to extend their life span. In addition to the introduction of the new SustainaSole styles, Sanuk announced to further reduce its ecological footprint by using sustainable hemp, sustainable leather and other recycled materials.
