Amazon.com | adidas Ultraboost Cc_1 DNA Mens Shoes Size 4 。Excellent condition, no visible wear! Rare find. Ultraboost technology is a huge statement in the sneaker world, and adidas has been breaking down the boundaries of comfort since 2015 when this revolution began. Every year, the three stripes introduce new models with the unique million-microparticle technology, and the adidas Ultraboost Web DNA is no exception. The biggest change from its predecessors is the update to the traditionally exposed midsole, which is wrapped in flexible 3D Stretchweb - for an even better feel of impact and bounce. The sneaker is partly created from recycled materials dredged up from the ocean floor as part of a collaboration with Parley For The Oceans. So experience the comfort of these sustainable sneakers.
