Fresh off a star-studded debut with Ronnie Fieg’s Kith, the EX89, formerly the GEL Extreme is back with a bang. Paying homage to the Boston Celtics, a crisp white leather base is overlayed neon-green and black, while a retro logo is stitched above a mesh tongue. A stability clip wraps the heel, while underfoot we have an off-white GEL™ midsole and dual-tone rubber outsole.
