The adidas NMD shoes aren't tied to any one era. They're based on '80s running designs, infused with technology from today and then turned up with style fit for the future. So when you step in, it's kind of like you're time traveling. Wherever you wear yours, you can count on feeling comfortable thanks to the plush and responsive BOOST midsole that gives back energy with every step you take. Made with a series of recycled materials, this upper features at least 50% recycled content. This product represents just one of our solutions to help end plastic waste.
