Absorbs shocks received by the sole, knee joints, and ankle from body weight. Provides even pressure distribution due to the different density of silicone it possesses. The blue silicone in the metatarsal and heel areas is softer for better pressure absorption at these specific points. The perforated surface helps with smooth air flow and the "breathability" of the foot.
