The Friction U shoe from Millet was specifically designed for movement in rocky environments (Via Ferrata, access to climbing terrain, etc.). It is therefore a favourite of all those who follow the motto "the rougher the road, the more fun". However, it can also be used for classic hiking and casual wear. Wherever you wear the Friction, you'll always appreciate its sturdy construction and unmistakable design. The Friction U boots have been perfectly tailored to make you feel comfortable in them even beyond your usual comfort zone. Their cornerstone is the grippy Vibram® Litebase outsole with a climbing zone that gives your steps confidence when moving over rocky terrain. Like the climbing shoes, their lacing has been extended to the toe. This allows precise tightening and a perfect fit to the foot. A durable suede leather upper material with reinforcement in exposed areas has been used. Cushioning midsole with double stiffness.
