If you think soft and springy soles are good, Adidas running shoes have what you need. The company pioneered the use of Boost, a specially formulated thermoplastic polyurethane (TPU) from German chemical company BASF with properties that have gained millions of runners as devoted fans. Boost provides incredibly soft cushioning while still being springy. The Ultra Boost ST has more Boost than any other shoe, and the result is unmatched heel cushioning combined with energy return that’s truly off the charts, matched to the stability features that support shoes need, making the Ultra Boost ST one of the best Adidas shoes for running.
