When running, the foot typically experiences forces of up to three to five times the runner’s body weight during heel strike. The GEL-KINSEI’s dual-density rearfoot GEL absorbs these impact forces in conjunction with the midsole material and construction. Since the density of the discrete GEL units on the medial side is greater than on the lateral side, runners experience an accurate reflection of the shock attenuation at touch-down laterally, as well as stability as the load is transferred medially from contact to foot-flat. In combination with the GEL, there are also grooves in the rear foot, which help to stabilise the foot during heel contact. The shock absorption, improved cushioning and greater stability provide enhanced comfort and a reduced risk of injury. This allows the runner to focus on running and performance. Advantages: - shock absorption - increased stability - improved running comfort - reduces impact
