Key Performance Technologies
- Full-Length Li-Ning Super BOOM Cushioning: Delivers explosive energy return and superior impact protection. The advanced foam compound provides responsive bounce for powerful drives, quick takeoffs, and soft landings, reducing fatigue during all-game wear.
- Activated Carbon Core Plate: Integrated one-piece carbon-fiber support plate provides exceptional anti-torsion rigidity and stability. This 'sandwich structure' with the BOOM midsole ensures precise guidance, smoother transitions, and secure foot lock-in during aggressive cuts and step-backs.
- GCU (Ground Control Unit) Outsole: Engineered for all-weather dominance, the full-foot GCU traction pattern delivers instant stopping power without slipping. Designed for extreme directional changes, it provides reliable multi-directional grip on both indoor hardwood and outdoor concrete courts, ensuring slip-resistant performance in dry and wet conditions.
- IBR Upper Construction: Features three Injection Blown Rubber (IBR) components integrated into a lightweight TPEE and textile upper. This innovative construction offers abrasion resistance, flexibility, and strategic breathability while maintaining structural support for high-intensity play.
