This Acronym x Lunar Force 1 SP ‘Zip’ released in September 2015 alongside two additional colorways. This pair, like the others, showcases a design that enhances the on-off process, thanks to an extended tongue and the addition of zippered closure on the lateral side. An all-white leather upper sits on a Lunarlon midsole, accented with a partially detached Swoosh and a heel coated in Bright Crimson.
