About the Nike Ja 3 'Cobalt Bliss'

The Nike Ja 3 'Cobalt Bliss' dresses Ja Morant's third signature shoe in an icy blue mesh upper with textured overlays in a darker shade of blue. On the lateral side, a vertical metallic silver Swoosh dips into a full-length Hybrid ZoomX foam midsole that offers improved energy return with each step. Morant's personal logo adorns the tongue and sockliner, while 'TWELVE' is inscribed on the rear collar. Underfoot, the rubber outsole features a traction pattern made up of raised mini 'Ja' logos.
