It's time to unleash your full potential. The lightweight adidas Ultra Boost Uncaged Parley running shoe trades in the midfoot cage of the original Ultra Boost for a more minimal, sock-like fit that molds to the shape of your foot and moves with you as you run. The shoe's seamless Primeknit upper is paired with a deconstructed knit collar, creating a barely there feel that turns the shoe into an extension of your foot. This particular Ultra Boost Uncaged was created in partnership with Parley For The Oceans, an organization dedicated to eliminating the use of plastic in an effort to save ocean life. Each pair of shoes recycles approximately 11 plastic bottles, all of which have been collected from ocean shorelines. The plastic is recycled into thread, which is then woven throughout adidas' signature Primeknit upper material. The result? Style that takes a stand. Do your part lace up the Ultra Boost X Parley.
