Adjusting bindings to fit different size boots is common practice among ski rental shops and people that share skis. Marker bindings have adjustments that allow you to fit boots that are both longer and wider than the average boot. In addition, you adjust the forward pressure to ensure the boots remain stable when locked in the bindings. DIN settings based on a skier's height, weight and level of expertise ensure the boots release properly when a skier goes down. Adjust Marker bindings to fit bigger ski boots one at a time.
Place the right boot and the right ski on a table. Note the length of the boot given in millimeters on the outside of the boot sole.
Open the adjuster lever on the side of the toe piece by hand. Slide the toe piece forward on the rails by hand and align the indicator with the appropriate millimeter mark on the binding. Close the adjuster lever firmly against the toe piece.
Identify the wide metal tab between the rails at the base of the rear binding. Lift the tab up with the tip of a screwdriver. Slide the rear binding back until the indicator aligns with the appropriate millimeter mark on the rear binding. Push the tab down firmly with the butt of the screwdriver handle.
Push the toe of the right boot against the inside of the toe piece on the binding. Turn the width-adjustment screw at the side of the toe piece to the left with a screwdriver to widen the receivers so the boot fits fully into the toe piece.
Push the heel of the boot fully down in the rear binding. Lift the rear release lever up by hand to lock the boot into the binding.
Identify the release scale and adjustment knob on the release lever. Turn the knob to the right or left, as necessary, and adjust the forward pressure to the center-mark on the scale. Lift the release lever and take the boot out of the binding.
Enter the skier's personal data into a DIN setting calculator to determine the DIN number. If a calculator is not available, refer to the skier's weight, height, age, expertise and boot length in the columns on a DIN chart to determine the number.
Locate the DIN numbers in the viewing window on the toe piece. Turn the DIN screw clockwise or counterclockwise, as necessary, to align the skier's DIN number with the indicator in the window.
Repeat the steps and adjust the left binding to fit the left boot. Adjust the DIN setting to the skier's DIN number with the screwdriver.
