Shop the Nike LeBron 21 'Optimistic'. This shoe features a psychedelic, mismatched color gradient. The left shoe fades from Bliss Pink to Laser Orange, while the right shoe displays a color gradient from Photo Blue to Vapor Green. The mesh upper boasts a 360-degree zonal cabling system for superior containment, creating an optical illusion that gives the upper a more molded appearance. Contrasting vibrant hues are found on the Phylon midsole, which houses Zoom Air cushioning in the heel and forefoot. A TPU shank plate supports the foot and provides structure. The exposed cabling system symbolizes the ridges on an oyster shell, representing LeBron’s desire to protect his daughter. Closure: lacing. Toe type: round toe.
