These Adidas kicks are woven from Biosteel fiber, a material designed to replicate spider silk that was developed by a German biotech company. The material is lighter than other synthetic materials and is quite strong. It’s also, perhaps most notably, 100 percent naturally biodegradable. The material is a sort of biomimicry inspired by spider silk. The Biosteel yarn is created using natural carbon sources that are fermented and converted into a white powder. The spider-inspired fabric is 100 percent biodegradable and bio-sourced. And, unlike other materials used in shoe production (see: leather), it’s completely vegan. After the presentation, the company pulled the curtain back to reveal the shoes with a bit of theatrical flair. The sneakers retain a similar aesthetic as their predecessors in the Futurecraft line.
