ADIDAS AND ALLBIRDS For wringing carbon out of shoes you'd actually wear Both Adidas and Allbirds have been committed to creating more Earthfriendly footwear for several years, but their first collaboration dropped in May 2021 when the two brands introduced what they dubbed Futurecraft.Footprint. The concept shoe achieved the breakthrough of requiringljust 2.9+ kilograms of COQ emissions to make; for comparison, Allbirds' flagship \\Vool Runners' carbon footprint is 9.9kg C02. The Futurecratt.Footprint brings together the sustainable progress that both companies have made into a single form: The midsole is based on Adidas' Lightstrike midsole but made with Allbirds' biobased sugarcane. The upper is 77% recycled polyester and 23% Tencel, which is made from wood pulp. Unlike a lot of concept projects, though, the companies launched it commercially in rindDecember, a lowcarbon running shoe that was more than just for show. The 8120 sneakers, which were available only in white, quickly sold out in all but the most extreme sizes. The companies have announced that a wider releaseiin four new colorsiwould come in spring 2022
