This freeride-friendly boot features Rossignol’s Posi-Block hike/ski technology, which creates a releasable cuff for downhill performance as well as freedom of movement for uphill travel. Sensor Grid, a milled out grid visible on the lower shell, reduces weight without loosing power. Other details include a 100 mm last, OptiSensor 3D Thinsulate liner, grippy soles and the option to use interchangeable rockered soles.
