Adidas and Parley for the Oceans are back with another sustainable take on some of the brand’s hottest models, as the Ultra Boost 3.0, the Ultra Boost Uncaged, and the women’s exclusive Ultra Boost X will arrive on May 10th.

The creations are all noteworthy not just for their head-turning colorways and uniquely comfortable Boost cushion systems, but also because it implements the Parley A.I.R Strategy – in which they avoid using virgin plastic, intercept plastic waste, and redesign new alternatives for footwear that’s not only good-looking but good for the environment. Each pair reuses an average of 11 bottles per pair.

Each Ultra Boost option has laces, heel webbing, heel lining, and sock liner covers created straight from recycled PET material.
