Putting lifts on boots

post #1 of 8
Thread Starter 
I apologize in advance if this has already been asked - I did a search and could not find anything.

I have Volkl Racetigers with the Piston/Motion setup. I have size 15 feet, which gives me boot out at pretty low (IMO) edge angles.

In the gear thread, several have said that I need to put lifts on my boots.

What is the maximum lift I can put on?

How stressful will the added lift be on my body (knees specifically)?

How much more edge angle might I actually be able to get?

That is a start, once you guys give me some answers, I will probably have more questions.

Thanks in advance.

What boot are you skiing in? This would be helpful info.

Rossi Power 21.

As per your post in the other thread, it sounds like I can not put a lift on it. I will have to check the boot when I get a chance.

You can pretty much lift almost any boot. 8MM really quite a bit.

Try this..

Put your boot on a hard surface and tip the boot over until you can see where you might boot out.

Then put 8mm under your boot (probably use a phone book and open it up so you get about 8mm of lift) and then tip the boot over to see how much further you can tip that boot over..

It will put more stress on your knees and body so unless you really need that much lift, I would suggest you go for the minimum amount of lift you need to get the angles you want. Unless you are racing and willing to take the higher risk of injury, I don't think it's worth it. But then again if you were racing at that level, you could probably get a boot company to build you a custom boot.

If the boot has removable lugs you will put more stress on the screws that hold the lugs in place but I don't think its enough to cause a problem I would have to defer to the boot pro's that really put the boots through their paces to answer that question.

Skiing on slightly wider skis would help a little too. Actually you should consider this when you do your boot tipping test.

Boots with removable toe and heel 'walking plates' almost always have hollow lugs, you can't take enough material off the top of the lug to bring the boot back to DIN standard. I'm not posative that a rossi power 21 falls into this catagory...but I'll bet it does.

If voids are reached when routing they can be filled with a quick set epoxy then rerouted.

Another consideration for you Phil, is with a size 15 boot your delta angle is much flatter than a size 8, so you may want to lift your heels a bit more than the toes depending on how your fore/aft balance feels? If you notice that you struggle to stay centered or have to break at the waist alot to get pressure to your ski tips you may want to add more lift to the heels (8 heels and 5 toes or 5 heels and 0 toes).

Another opinion, skiing on wider waisted skis is IMO much more stressful on your knees than vertical lifters are. The higher you are off your skis the longer it takes to change edges. So you must be quicker or give yourself more room to turn from the sides of the run. This issue in my opinion is worth more consideration than knee stress.

Another thing to consider is that if you want you can start small and grow the plates over time you can always go up it is very difficult, and in my shop impossible to go back down.

good point Mosh!

another thought to consider. Some boot manufacturers do not take care to maintain the same ramp angle throughout a model size run. So as the boot sizes get larger the ramp angle gets flatter. This should be checked in your size 15's to insure you are not too flat?
