Nike designed this shoe with a shell-like appearance to honour how LeBron feels the need to always protect his daughter similar to how an oyster shelters a pearl to help it reach its full potential. The colours and graphics of the LeBron 21 nod to this special relationship.
With an Air Zoom unit and soft cushioning, the LeBron XXI gives you flexibility and power without a lot of excess weight to slow you down. Ideal for rim runs, fast breaks and racing up and down the court, they help you keep playing at the top of your game until the final buzzer sounds.
Nike opted for extra flexibility in the forefoot over packing in more Air units for a kid-right fit that's perfect for your developing game. A bottom-loaded Air Zoom unit in the heel adds cushioning for when you're taking jump shots and making the leap to the next level of your game. Soft foam in the midsole feels soft and smooth while keeping you low to the ground, which helps you stay connected to the court. The airy, breathable fabric on the upper is made of a dimensional mesh that’s lightweight, durable and contained.
HOW TO FIND THE RIGHT SIZE
Wear the type of socks you'll wear with your shoes and measure feet in the afternoon (feet typically swell during the day). Distribute weight evenly before measuring.
How To Measure
1. Stand up straight on a hard surface with your heel against the wall.
2. With a soft tape measure or ruler, measure the heel-to-toe length.
3. Make sure you measure to the longest point of the toes.
Find The Right Size
Use your measurements and the chart below to determine your shoe size.
Please Note: Your heel-to-toe measurement (in cm) may be slightly shorter than the CM measurement you will find on your shoe box. We have made minor adjustments in some cases to account for the materials of the shoe and ensure a proper fit.
