Last year adidas unveiled their most comfortable Ultraboost model yet. They've taken that design and refined it, delivering a more sustainable and comfortable running shoe, to ensure you reach that runners high. The Ultraboost 22 utilises Primeblue materials for the Primeknit+ upper. These are constructed with 50% Parley Ocean Plastic and 50% recycled polyester. Sustainable materials are applied for the Continental Rubber outsole. The classic Stretchweb construction delivers the same peak performance, but now uses Natural Performance Rubber, sourced from latex tapped from rubber trees. Built on a thick bed of Boost cushioning, the Ultraboost 22 are engineered to deliver smooth, responsive strides. Crafted in a rocker shape with a new LEP system, they smooth transitions and deliver a snappier, more responsive sensation through transitions. This helps runners preserve their energy, allowing them to push the pace harder or strive for longer distances. Get moving and fall in love with running in the Ultraboost 22.
