While not as popular as when the Ultra Boost first made its debut, adidas continues to add to its lineup with new designs of their beloved runner.

Expanding their Ultra Boost S&L series, adidas is set to release a brand new “Grey Two” colorway. It features a mix of Grey tones on its Primeknit upper paired with leather lace cage and suede heel counter. A White Boost midsole atop a Black rubber outsole completes the design.

Check out the official photos below, and look for this Ultra Boost to release in May at select retailers and adidas.com. The retail price tag is set at $180 USD.
