Looking to focus more on performance than frills? The Adidas Pure Boost sacrifices bulk for a lightweight profile. The tongue has a construction that maintains the shoe's simplistic design; it's actually double-folded upper fabric. A knit upper keeps your feet comfortable and your movements unrestricted. It might not be the most cushioned Adidas shoe, but, as its name implies, the PureBoost is designed to keep you moving at high speeds during shorter runs. With that said, it does have foam cushioning in the midsole, and it still manages to be one of the most comfortable Adidas shoes available.
