Okay i got new boots and they are only 9mm shorter(from 359mm down to 350mm), if i slide my rear bindings forward just enough, will i need to release the din and reset it on the front and rear, or am i fine without doing it.
What do you mean release the DIN? Just slide the heel piece until it's the right length for your new boots, click in and check the forward pressure marker, and when it's good....you're fine.
