The adidas Futurecraft Biosteel has been officially unveiled, which is the world’s first performance shoe made using Biosteel fiber – a replication of natural silk – at the Biofabricate Conference in New York.The adidas Futurecraft Biofabric prototype shoe features an upper made from 100% Biosteel fiber, a nature-based and completely biodegradable high-performance fiber, developed by the German biotech company AMSilk. The material offers a unique combination of properties that are crucial in performance, such as being 15% lighter in weight than conventional synthetic fibers as well as having the potential to be the strongest fully natural material available.“This concept represents premium innovation. By using Biosteel fiber in our products, we have achieved an unrivalled level of sustainability. We are moving beyond closed loop and into an infinite loop – or even no loop at all. This is a pioneering stride forward beyond sustainability into a new territory of bionic innovation.”Like many adidas Futurecraft designs, this new Biosteel version is just a concept at the moment and there are no future plans of a release. But one in the near future could be a possibility.
