Cool-weather running shoes made using recycled materials.

The Ultraboost has been helping runners chase their goals and sneakerheads dial-in their style since 2015. Now we've created a pair to help you tackle cold days in comfort. Like a winter-jacket for your feet, these adidas shoes have insulation and COLD.RDY to keep feet warm and dry. Continental™ Rubber works together with Boost to ensure confident steps. This product is made with Primegreen, a series of high-performance recycled materials. 50% of the upper is recycled content. No virgin polyester.
