Shoes last month Share Tweet Pin Share After debuting in a round of pastel spring looks, adidas‘ UltraBOOST Laceless model now returns to the classic “Core Black” colorway. On this slip-on model, the tried-and-true color scheme sees a black knit upper against a white full-length BOOST midsole and heel counter. The runner’s signature forefoot ribbing and elastic ankle opening stay stealthy in tonal black, while a thin black outsole adds another touch of contrast to round out the design. The adidas UltraBOOST Laceless “Core Black” will release on May 1 at Livestock and select Three Stripes retailers. For more UltraBOOST models, take a peep at adidas’ launch of the AM4NYC sneaker at the SPEEDFACTORY Lab Experience in Brooklyn.
