These adidas Ultraboost sneakers are ready to tackle all sorts of terrain. While they may be lightweight, with an upper crafted from supportive adidas PRIMEKNIT, these running shoe grip even rain-slicked surfaces. The outsole is made from Continental™ rubber that performs just like world-class tyres. And with BOOST and a snug-fitting heel, they'll stay comfy even when you take them for a spin off-road. Made in part with recycled content generated from production waste, e.g. cutting scraps, and post-consumer household waste to avoid the larger environmental impact of producing virgin content. 25% of the components used to make the upper are made with a minimum of 50% recycled content.
