The upper is fixed to their signature ribbed TPU midsole and rubber outsole. Both come in a darker shade of grey than the upper. Full length drop-in Boost™ technology makes this one of the most comfortable sneakers ever. Other details include grey round laces, defined center stitching, and made from sustainable and recycled materials as part of Adidas’ End Plastic Waste Program.
