New, Unused SEV (for men and women) Running - RUN Speed Support ● Change your run with insoles. ● S size: 23-24 cm ● SEV is a patented technology designed to unleash your natural performance. ● SEV INSOLE RUN: Creates a comfortable running environment. 1: Speed up with a strong push-off: The balance of "flexibility" and "stiffness" of the stabilizer supports speed up from a strong push-off. Furthermore, by firmly supporting the arch from the heel, it prevents side-to-side wobbling and reduces speed loss. 2: Smooth weight transfer makes running more efficient: By adopting "PORON," a shock absorber with excellent high-energy absorption. It absorbs and mitigates the impact on the heel, supporting smooth weight transfer when stepping. 3: Excellent grip reduces loss: "Nanofront" quickly absorbs and disperses sweat from the soles of the feet to prevent slipping. Furthermore, the curved structure, designed with running movements in mind, supports the arch and enhances grip performance from the inside.
