Since the LeBron 20, James has sent a strong signal through his signature shoes, not only for his own exclusive basketball shoes, but also designed for the next generation of basketball players.
LeBron 20 is inspired by the son, LeBron 21 by the daughter.
The LeBron 21 design is inspired by LeBron’s daughter Zhuri, hoping to be like a shell protecting the shining pearls in the body, and is committed to escorts the new basketball players.
The white gold colorway looks pretty. It’s totally different with previous LeBron series shoes.
The shoe body is covered a piece of thin and soft leather. The texture is great.
The biggest lightspot of LeBron 21 is the double-layer upper design with built-in flywire, and thus outline the appearance of shell texture.
The Swoosh logo on both sides of vamp are different. 
The outboard Swoosh logo is three-dimensional. And the inboard Swoosh logo is embroidered and hollow-out design. It shows the double-layer upper structure.
The forefoot sole is built-in Zoom Turbo, and the heel uses a piece of 13mm Zoom air cushion. And it uses full-length Cushlon 2.0 foam.
The arch position has built-in TPU anti-torsion plate. And we can see it from the hollow-out outsole. The hollow-out design reduce the weight.
The outsole pattern is complicated. It’s also stiff. The abrasive resistance should be good. But it uses crystal rubber. So it’s not suitable to play basketball on outdoor cement court.
The front end of shoe tongue has a piece of gold shoelace buckle. The heel shows the shell element. And it has stabilizing plate on the heel to reinforce the supporting performance.
Both sides of the shoes have many ventilated holes. The shoe tongue is made of mesh fabric. The air permeability is good.
The shoe-pad is thick and soft. It’s made of environmental protection material. And it’s printed with 4 grand champion rings on the fingers.
The lining of shoe tongue is soft and comfortable.
It’s easy to put on and take off.
The pretty appearance is also good-looking for daily dressing.
The center of gravity is not high.
The unit weight of EUR42.5 is about 416g. It’s lightwe than I thought, as it’s made of leather and rubber outsole.
After fastening the shoelaces, I can obviously feel that the complete tightening of the flywire from front to back. You can adjust it by your request.
The ZOOM Turbo cushion don’t offer obvious feedback when walking, but the feedback is obvious when jumping.
The arch support is also great.
The upper is soft and comfortable. It won’t oppress the instep.
They fit true to size. The half-sole is a little wide.
The outsole rubber has anti-rollover design.
The first released model uses crystal rubber outsole, not XDR outsole.
If you prefer to the high abrasive resistance outsole, you can wait for further other colorways.
