Marker F10 bindings are perfect for your touring trips into the ungroomed backcountry with great properties for hiking, climbing and descending. They have a DIN setting interval of 3.0 - 10.0. Your DIN setting should fall somewhere in the middle of the DIN setting interval for the bindings to function most effectively. We recommend choosing a brake arm that is 10 mm to 15 mm wider than the waist of your ski.
