HI-FIBER High Strength Fiber UpperFeaturing the HIRACER HI-Thread upper with a density lower than human hair strands, it forms breathable micro-holes via specialized weaving for enhanced ventilation, toughness, and durability. A built-in rhombus support reinforcement structure ensures a seamless, snug fit. Combined with an integrated flywire tongue, it creates a technologically advanced, highly breathable shoe upper.Full-Length Dual-Arch Propulsive Carbon PlateCarbon fiber material is arranged in multiple layers and directions according to the motion demands of the forefoot and heel, with a dual-arch carbon fiber structure designed. Compared with traditional shovel-shaped carbon plates, it delivers dual landing resilience and propulsion, doubles the acceleration of energy rebound, and turns every step into a catapult-like launch.HiFoam∞ H-PEBAX Supercritical Foaming MidsoleThe nylon elastomer H-PEBAX material undergoes a supercritical physical foaming process, which reduces midsole weight while delivering enhanced shock absorption and resilience. It boosts energy return efficiency, shortens rebound time, and pairs with a dual-arch carbon plate to provide sustained energy support for marathons.AGCS Wet Ground Anti Slip and Wear-Resistant OutsoleThe outsole of the All Ground Control System is made of polyurethane material, delivering superior slip resistance on wet surfaces and excellent wear resistance.
