Adjust bindings for smaller boots?

Stangyhank69Lets say I bought some smaller boots and I am adjusting my bindings to fit them. 2 questions here:

-how short should I make the length? My boots will “lock in” at a few different levels of shortness. does it matter?

-how should I adjust the DIN? Intuition says I should lower it because now the lever is smaller.

please excuse my lack of terminology. I am just a caveman.

Wrong in both cases please take them to a shop

Not always an option, hence the question

It's always an option. Especially where you go skiing- there are tons of shops near or at ski resorts.

This is far more complicated than you think, especially with certain bindings that have multiple areas of adjustment in order work properly. If you don't know what you're doing, you are really gambling with your own knees and anyone who gives you advice on how to do it can be legally held liable. It's not an uncomplicated thing you're asking for.

Having accessible information makes things safer for everybody. Especially when, as you say, it’s complicated. The alternative is a few people extra going to a pro, and a lot of people trying to wing it on their own without information. Which means a lot more busted knees

I don’t think there is any liability in answering objective/factual questions on an pseudonymous message forum.

In my case I swap skis/boots with my friends several times a day—often very early in the morning. It is infeasible to use a professional

Then accept the risk of blowing a knee or accept the risk that whatever you read online may be false dude…

stangyhank69 long hair dont care!!

This isn't exactly rocket science. You should be able to find the installation manuals for any given binding online, use this and a few youtube videos to become very familiar with the bindings on which you work. Do some reading on here, like troubleshooting threads for particular bindings and you can likely do this yourself or with your most capable friend. YMMV
