DIN settings are the most important safety element of ski bindings. "DIN" stands for Deutsche Industrie Normen, which is the German industrial organization responsible for setting the standards for binding release tensions. These settings are determined by your:
Beginner — 3 to 6
Intermediate — 5 to 9
Advanced — 6 to 12
Racer — up to 24
Most recreational skiers are advised to lower their DIN settings after they reach the age of 50.
