DIN is the release value setting on alpine ski bindings. It is worked out from your weight, height, age, boot sole length and skier type, using the ISO 11088 standard that shops follow. Choose a binding whose DIN range covers your setting in the middle, and have a certified technician set and test it, especially after changing boots.
Bindings release your boot from the ski in a fall. DIN sets how much force it takes.
What sets DIN

Common questions
Can I set my own ski bindings?
Shops use the ISO 11088 method and test equipment. Having a certified technician set them is the safer choice.
What DIN range do I need?
One where your setting sits in the middle of the range, not at the top or bottom.
Do I need new bindings with new boots?
Not always, but the bindings must be adjusted to the new boot sole length and checked.
