A mechanical solution for friction-induced heel irritation, utilizing a multi-layered high-density sponge and a professional-grade pressure-sensitive adhesive. The 4D anatomical design follows the curve of the Achilles to prevent epidermal shearing and condition the skin surface by mimicking its natural cushioning.
The breathable fabric top-layer manages moisture more effectively than solid gel alternatives. For maximum longevity, the internal shoe surface should be cleaned with isopropyl alcohol before application. This prevents "heel slip" and protects both the foot and the internal shoe lining from friction damage.
