The Kingfoam Elite Sport Quantum Heel Mid Insoles feature heat-activated Quantum Heel technology that allows the internal gel chamber to mold to your specific heel shape, providing professional-grade rearfoot control and stability. Engineered with proprietary Kingfoam cushioning, these insoles are lab-tested to absorb over 90% of impact energy, significantly reducing joint damage and fatigue during heavy skate sessions. The mid-profile 7mm heel is specifically designed for standard-volume footwear, offering elite-level shock protection and a custom orthotic feel without altering the fit of your favorite shoes.
