The Tri-Arch support control is an arch design of the footbed based on the three arches of the foot: medial and lateral longitudinalarches and transverse arch. Tri-Arch is ergonomically designed to keep the original curvature of the three arches, which offers a more comfortable support to the sole, evenly distributes the pressure, and enables better controllability.

Drop-in midsole combined insole with midsole, not only increase its durability, but also provide more comfortable and nice support to the longitudinal and transverse arches.
