The Sensus has a bold lookthe manufacturer has borrowed elements from the earliest known shoes and combined them with modern materials and manufacturing methods. The Sensus is a pure barefoot shoe: the 3 mm thick sole protects the skin of your foot, but does not support or guide your step, nor provide significant cushioning. - The upper material is premium-quality leather with a unique pattern. - The last is wide enough to let your foot spread naturally with each step - This model does not include insoles - The outsole has a striking and practical pattern that follows the shape of the sole of the foot - The insole material is leather Start using barefoot shoes gradually, in small doses: your muscles and tendons face a different challenge if youre used to cushioned and/or stiff shoes. Give your body time to adapt and experience your stride evolving!
