From groomers to powder, the Lange RS 130 LV Ski Boot provides us with precise control and unrelenting power that lets us ski to our fullest capabilities. The 97mm last is narrower than most so that there is no lost power when we need to transfer it to our edges. This power is further backed up by a stiff 130 flex that resists deep flexing to move that energy to our edges so that we can lay trenches, pivot on a dime, and go faster than ever before.
