Ultraboost shoes have been on the vanguard of running technology since their release in 2015. This version has an adidas primeknit upper that wraps the foot for a lightweight and breathable feel. A 3d-printed midsole has a lattice structure with denser parts and more open parts for targeted cushioning and support. These shoes don't just look like the future. They feel like it, too.
