adidas’ Ultra Boost line is known for its plush and responsive cushion tech and, for that reason and more, is a favorite among runners. The Ultra Boost 19 helped solidify the Boost line as a technical running shoe line. The Ultra Boost 20 takes it a step further by introducing additional tech like tailored fiber placement on the Primeknit upper and a redesigned heel. Oh, and did we mention that the 20 line features a stunning collection of colorways thanks to a collab with the ISS (International Space Station) Lab? It’s SO eye-catching.
