Fore Aft Alignment

post #1 of 14
Thread Starter 

I just found this forum and your advice to help others is refreshing.


I have been having a problem that has been plaguing me for years. I changed boots about 6 years ago and that's when things went bad. I had a pair of Technicas that had a heel lift under the liner as I have limited dorsiflexion. They also had a 2 mm toe lift outside of the boot. It took quite a while to get this all figured out, but in that configuration my fore aft alignment was pretty good.Subsequent to the Technicas, I have been through a pair of Heads, Nordicas, and Rossignols with terrible problems with fore aft balance - to the point of falling over backwards. I currently am in a Dalbello model with a small heel lift and for whatever reason I am much more balanced in the fore aft plane then in the previous three boots. But maintaining balance is still a struggle. Even just getting off the lift or skiing an easy green run I can find that sometimes I simply cannot keep my ankles flexed and stay in shin contact with the boot. It is terribly frustrating. I tried both an external heel and toe lift under the boot but that really doesn't help at all. After trying lots of combinations I find a small heel lift under the liner together with softening the flex (adjustable on the Dalbello) has benefited me the most. I have taken several lessons and instructors have observed the problem but no one can clearly identify what is happening. Realizing that this is tough to diagnose, has anyone else had a similar issue and if so, what boot modifications or suggestions might you have? Thanks for any help.

Many of us have problems with fore/aft balance when we change boots---- factors are the boots forward lean----boot board angle-----delta angel (difference between heel and toe height on binding)---- the one issue you bring into the mix is the size of your calf at the top of the boot.


What is the circumference of your calf at the top of the liner?


How do you have the forward lean set on this boot?

Thanks very much for responding.


The circumference of my calf at the boot top is 16 ½ inches.


I wrote Dalbello about the forward lean and this is their response: “The cuff angle is fixed at approximately 12 degree, but it is effectively variable because the boot has an adjustable boot board ramp angle. I'd say between 8 & 14 degrees depending on set-up.” Also with additional info that Dalbello provided about the adjustable ramp angle, the ramp angle that works the best for me is about 7 degrees.


One fitter put the rear spoiler in the boot but that just seemed to force my legs forward (obviously) in a somewhat artificial way that really did not help that much and left my thighs really sore at the end of a short day. So I don’t think that aligned me properly.

Years ago some boots came with variable forward lean, but during that time very few folks knew how to set boots up correctly.

Since the adjustment wasn't being used and cost $ to put on the boots the whole idea was dropped.


If you were to measure your boots forward lean by standing the heel against something vertical and measuring to the liner at the

top of the shell, then adjusting the forward lean to the most upright position and measure again.


You need about 50mm of forward lean when measured as described above---boots can be bent back at the upper cuff to accommodate this issue.

Could you please explain what you mean by "bent back at the upper cuff" and tell me how to do that? I am sorry but I don't quite understand. I think you mean that the distance to the top back of the upper cuff to a vertical wall, with the heel placed against that vertical wall should be approximately 2 inches. Is that correct? If so, how do I do that?


Thanks again.

Follow this link   http://southern-ski-tools.southernski.com/tjs4.html with this tool we regularly do this service for folks with larger calf muscles and the results are great.

Thank you again. Since we have about 2 more weeks of the season left, is there anything else you could suggest until I can have the modifications done?

I just did a pair of boots for a fella in NY a week or so ago----He shipped his boot to me with the dimension of his calf and we stretched them and sent them back the same

day. 50.00 plus shipping.

I'm not certain which Dalbello you have but the one I am familiar with that has interchangeable boot boards is the Scorpion, although it doesn't really matter.  Is it possible that you lack pressure on the top of your foot?  Many things can put you in the back seat in skiing, some of them are related to fore/aft position and some simply to accelerations and terrain pitch changes.  In order to recover from the back it is necessary to pull forward with the ankle flexion muscles and for that to happen your foot must have something above it to brace against.  If it feels as if there is a space above your instep then you simply cannot balance effectively.


What happens if you put a pad of a dense material (about 1/8" or more) between the shell and liner on the tongue over your instep.  Possibly the increase in pressure is not comfortable but what happens to balance?

with a 16 1/2 " circumference calf muscle the first place you have to look is at the top of the boot as Mike has said, you are using up all the limited dorsiflexion that you have simply to stand in your boots, straighten this up to accommodate this calf muscle and then you can start to get centred and deal with the rest of the balance issues

I don't think I can place anything on top of my foot, even 1/8 inch material, and still get in them. They are a really snug fit and I don't have any room at all above my foot. Thank you for the suggestions though. I appreciate any help I can get.

In regard to my ridiculously large calf muscles, is there a way to simulate Mike's suggestion, just to give it a try?

post #13 of 14

the only way to simulate flaring the cuff back (as far as i know) is to flare the cuff back, certainly make sure there are no spoilers or shims in there would eb a start, but it will need more than simply that

post #14 of 14

If you were to flare the cuff back and didn't like the results all you would need to do is add a spoiler between the shell and liner to push your knee back forward.  there is no way to simulate this effect, but once accomplished you wouldn't want to go back to skiing in a sitting back position.
