Built to provide improved stability, the Adidas Ultra Boost ST sees a revamped upper with a mostly unchanged Boost midsole. The most obvious updates here are the redesign of the plastic support cage at the midfoot and an updated Primeknit pattern. The Ultra Boost ST is also equipped with a Continental rubber outsole for added durability, which should help to remedy one of the biggest complaints about the original sneaker.
