“We saw the XX as a chance to celebrate the next 20 years for LeBron. The stitched tag inside the tongue says, ‘Designed and Engineered to the Exact Specifications of the Next Generation.’ We took that line seriously as we designed the shoe. We had players like LeBron’s sons Bronny and Bryce in mind. We wanted to get in their heads and learn about what young players were looking for.” – Jason Petrie, Senior Footwear Designer for Men’s Basketball
The shoe is the lightest edition from James’ signature line. The collar lining includes a Nike technology called “Nike Sphere” that initially appeared in the Air Zoom Generation. The cushion is provided by a foam midsole that contains a top-loaded Air Zoom Turbo unit under the forefoot and a larger Zoom Air unit under the heel.
Additional tech specs include a synthetic-wrapped lateral guardrail that helps secure the foot in place. Plus, a carbon fiber midfoot shank provides energy return and torsional rigidity. Traction is provided by a multidirectional outsole pattern that grips the floor.
