The Undefeated x Nike Air Zoom Spiridon 'Thunder Blue' showcases a gleaming chrome Swoosh on the upper, crafted from navy open-cell mesh with a color-matched suede mudguard outlined in reflective piping. Additional 3M accents land on the webbing eyelets, collar and pull tab. A green mini-Swoosh is embroidered on the forefoot, while a blue Undefeated tag graces the lateral heel. Wavy lines are etched along the Phylon midsole, supported by full-length Zoom Air cushioning underfoot.
