Ultra-responsive running shoes made in part with recycled materials.

Your hard runs feel easier in these adidas running shoes. The Ultraboost 5X delivers an extra push across each mile so you feel fresh from start to finish. With an integrated midfoot support that reduces the weight by 0.6 ounces, and LIGHTBOOST delivering 10% lighter cushioning the Ultraboost 5X is truly the lightest model yet. Feel secure in the Primeknit upper with molded external heel supports to provide the ultimate fit. The Torsion System between the heel and forefoot provides stability for a smooth, steady stride no matter how far or fast you go. It all rides on a Continental™ Rubber outsole for extra grip in wet and dry conditions to keep you confident on your feet.
