When the Ultraboost first dropped in 2015, it took the sneaker world by storm. And like a runner chasing a PB, we've been building on the design ever since. These adidas running shoes incorporate 3D Stretchweb around the BOOST midsole. This enhances the feeling of energy return, so you feel fresh on your feet all day. Throw in the adidas PRIMEKNIT upper, and you get a comfortable shoe for short distances and daily wear.
