HI-TEC®️’s functional Rollin Gait System (RGS) was developed by Vibram in collaboration with the HI-TEC®️ product team in 2011. Vibram® RollinGait System (RGS) is an innovative technology that helps the natural roll of the foot, blending form and flexibility. It has been specially developed to optimise energy output, reduce muscle fatigue and helps you walk for longer. When the foot first hits the ground, the centre of pressure moves from the heel to the metatarsus and then the toes. The unique curved shape of the RGS sole supports the natural movement of the foot on the ground, step after step. Less energy consumption + less muscle fatigue = more endurance.
