Adidas has launched the Stan Smith Mylo, its first shoe whose upper is made with the Mylo material, a soft, natural and renewable alternative to leather that uses mycelium, which comes from the roots of mushrooms. Developed by a biotechnology firm, Bolt Threads, Mylo is described by the company as a versatile material that can take on any color, finish or embossing, and its fibers are said to be very strong. The midsole of the Stan Smith Mylo uses natural rubber. As part of its commitment to end plastic waste, Adidas had launched earlier this year a version of its iconic Stan Smith shoe featuring a Primegreen upper made with 50 percent recycled material.
