adidas continues to explore the use of colored Boost cushioning with this upcoming Ultra Boost 3.0. This time, bronze gets the call, painted onto the shoe's midsole. The upper features Core Black Primeknit, a leather cage and matte-finished counter. Below, white Boost peaks through black Continental tire rubber. The "Bronze" Ultra Boost 3.0 is expected to release in May. Keep it locked for specifics in the coming weeks.
