Adidas released a 100% recyclable running shoe called Futurecraft Loop in 2018. The shoe's tongue, laces, vamp and midsole are made of TPU (thermoplastic polyurethane elastomer) and Boost cushioning technology.
Further to its promise to make shoes entirely out of recycled plastic after 2024, Adidas continues to work on the project, hoping to reduce waste plastic as much as possible. At the same time, Adidas hopes Futurecraft Loop will be the starting point for a production model that will allow old shoes to be completely recycled and used to make water bottles, tote bags and even new shoes. This,of course,is why futureloop doesn't use any glue at all.
Much of the Futurecraft Loop is made in China but assembled by a robot from Adidas's Speedfactory in Atlanta. Adidas says it took decades of research and development before it was able to make a Futurecraft.Loop out of plastic with both performance and durability without using glue. Even after 400 km of road testing, it remains in good condition. This special version of the Future Loop will only produce 200 pairs and will be available to certain runners for pre-production trial wear data collection. If you look at the shape, there doesn't seem to be a significant difference between a Futurecraft Loop and a running shoe. And with the use of thicker plastic, it's also re-attached a bit. But it uses Boost cushioning technology, which is comfortable and durable.
