EXPLOSIVE TAKEOFF, ENERGIZED REBOUND

ENRG-X midsole technology delivers resilient, responsive cushioning that minimizes energy lag — keeping every burst, cut and stride sharp, fluid and under control.

LATERAL LOCKDOWN, SIDE-TO-SIDE STABILITY

A large TPU wrap reinforces lateral support across the upper, reducing the risk of rolling during cuts and sudden stops — keeping every lateral move and directional change confident and controlled.

STRUCTURED SUPPORT, STABLE POWER TRANSFER

A lightweight mesh upper with targeted PP film reinforcement strengthens support and lockdown in high-stress zones — reducing unwanted movement during cuts and contact, so every push-off feels grounded and every drive stays in control.

BUILT TO LAST, COURT-READY EVERY GAME

An updated high-abrasion rubber outsole delivers enhanced durability against the constant grind of sprints, cuts and hard stops on the hardwood — extending the life of the shoe through every high-intensity game.

RACECAR-INSPIRED, BUILT TO TURN HEADS

Drawing from racecar design, the silhouette breaks away from the typical performance look — merging bold aesthetics with functional structure to deliver a speed-forward court style that commands attention on the court.
