DIN setting is defined as Deutsches Institut fÃ¼r Normung (German Institute for Standardization) setting for ski bindings. It is also called as release force setting, which can be calculated using skier type weight, height, age, type and boot length with this online DIN calculator
While skiing to reduce the chance of injury, ski bindings are designed to release skiers boot automatically in the event of crash. Release is based on the DIN setting. The amount of force required to release feet from the boot increases with increase in din setting.
