Big kids XXI - With Air Zoom units and soft cushioning, the LeBron XXI (also known as the LeBron 21) offers you flexibility and power without slowing you down with excess weight. Ideal for rim runs, fast breaks and racing up and down the court, they'll help you keep playing at the top of your game until the final buzzer sounds.Less Air, More FlexThe difference between this LeBron and the adult version? We opted for extra flexibility in the forefoot over packing in more Air units for a kids-right fit that's perfect for your developing game. A bottom-loaded Air Zoom unit in the heel adds cushioning when you're coming down from grabbing boards, taking shots and making the leap to the next level of your game.Movie NightCan you find all the movie references and details on these shoes? This edition of the LeBron takes inspiration from one of his favorite ways to cool down after a game: A relaxing movie night in his home theater with some freshly popped popcorn.Feel the FloorSoft foam in the midsole feels soft and smooth while keeping you low to the ground, which helps you stay connected to the court.Lightweight DurabilityThe airy, breathable fabric on the upper is made of a dimensional mesh that’s lightweight, durable and contained.Multi ColorNikeSneakersBoys / UnisexFull-length Zoom Air unitMesh upper360- Degree zonal cabling systemLow-top silhouetteStandard lacing system
