The Nike LeBron 21 is built for those moments that matter, designed to help make every attack a success and keep you going full throttle for every challenge, just like King James himself. Ideal for the court or street, large Zoom Air cushioning units from front to back provide superb comfort and flexible, responsive performance in any direction, with a soft midsole helping keep you on your feet. Mixed materials and engineered, dimensional mesh help ensure breathable flexibility that offers easy lightweight feel without any extra bulk, all supported with 360-degree zonal cabling for containment, while elsewhere the carbon fiber shank adds steady support.
