adidas is taking the subtle approach with the release of the Ultra Boost 4.0 as new colorways of the popular running shoe continues to appear on store shelves without notice. Featuring a newly engineered Primeknit upper, the Ultra Boost 4.0 doesn’t depart too much from the winning formula, but that may also mean UB fans are looking for something new. If you’re still a fan of the look or are just getting into the Ultra Boost craze now, get this new grey pair now directly from JD Sports.
