Use the shoe size chart below to find your US, Euro, UK and CM/Mexico shoe sizes.  Please note, this shoe size chart is ONLY a general guideline.  Shoe sizes do vary from brand to brand as each brand manufactures their shoes differently.  We strongly recommend measuring your feet at night because your feet expand throughout the day. 

Please use our Shoe Size Chart to help you convert your shoe size internationally.  Example:  If you wear a UK size 5 in women, you will be roughly a USsize 7 in women. 

Please use our Shoe Size Chart to help you convert your shoe size from women to men.  Example: If you wear a US size 8 in women, you will be roughly a US size 6.5 in men.

For fur boots, we recommend 1 size larger than what you measure.

Details

Where will your game take you? Lace up the latest from the King and find out. With an Air Zoom unit and soft cushioning, the LeBron XXI (also known as the LeBron 21) offers you flexibility and power without slowing you down with excess weight. Plus, we loaded this special edition signature shoe with details you won't want to miss, including a holographic upper and metallic gold Swoosh logo.

All-Star Design
Holographic accents work together with graphics inspired by your favorite basketball trading cards to give these shoes a look worthy of an MVP title. Plus, the included trading card frames some of the game's biggest stars as the superheroes they really are.
Less Air, More Flex
The difference between this LeBron and the adult version? We opted to swap out a forefoot Air unit for extra flexibility. The result is a shoe that's perfect for your developing game. A bottom-loaded Air Zoom unit in the heel helps cushion your landing when you come down from grabbing boards and making the leap to the next level of your game.
Feel the Floor
Soft foam in the midsole feels soft and smooth while keeping you low to the ground, which helps you stay connected to the court.
Lightweight Durability
Breathable fabric on the upper is made of a dimensional mesh that's lightweight, durable and contained.

  • Classic laces
  • Carbon fiber midfoot plate for stability
