The RU5 Invisible is ideal for competitive runners with its light padding for immediate power transfer and direct contact. Extra silicone threads on the inside prevent the running socks from sliding and an extra padded lip at the heel prevents friction and the development of blisters. Padding is the thickening in the fabric to give extra protection to the foot, so that it creates less pressure. In addition, mesh zones at the instep provide comfortable ventilation for the foot.
Fast moisture wicking and re-drying, thanks to three-layer material construction
Extra reinforcement for heel padding
Optimum fit, due to right and left padding and toe box
