Since making its debut in 2015, the adidas Ultra Boost has become one of the most popular sneakers the brand has ever released. This particular colorway of the adidas Ultra Boost features a red Primeknit upper with black threading. A red TPU cage with glossy black Three Stripes and black heel cup complete the design. A white adidas Sportswear logo stands out on the tongue. The upper sits atop a white Boost midsole and Continental rubber outsole that provides some of the best comfort available.
