Improving Ramp and Fwd Lean

post #1 of 7
Thread Starter 

I believe my boot/binding combination offers both too much ramp angle and too much fwd lean.  I have elevated the binding toepiece to correct the ramp angle,  but am considering how to effectively reduce the fwd lean inherent in my boots (Falcon CS Pro boots, Look PX12 bindings).

 

Here's what I'm wondering:

 

Can I raise the heel of my footbed (increase ramp angle inside boot),  and offset that by raising binding toe (bringing overall ramp angle back to where it is now)?  My thinking is that by increasing the internal boot ramp angle,  I'm effectively reducing the fwd lean of the boot cuff.  Of course,  I will be limited by how much room I have over my instep,  and at some point,  the heel would begin being pushed out of the pocket.  Also,  how much can I safely elevate the binding toepiece (I have a longish bsl of 336mm,  so that should allow more lift than short bsl's)?

 

My 3 boys and I all have similar feet/builds,  and I'm thinking we'd all benefit from these changes (they're on the same bindings,  but using Lange Comp 120LF's which also have excessive fwd lean).

 

I'd really like to try Nordica Dobermann WC's for all of us,  but college tuition comes first.  Hence,  I'm trying to make the best of what we have to work with.

 

Thanks for any thoughts/ideas.

The F lean of the boot too much for you, but is it pushing you too far forward from the upper/back of the cuff, or from the ankle joint/ boot flex point?

2 different problems, and 2 different solutions, (neither need heel lifts)

You can offset changes to internal ramp by changes in binding delta, but keep in mind decreasing binding delta also makes boot cuff more perpendicular to the ground (decreases forward lean relative the ground).  Can't think of a reason other than availability of screws that will limit binding toe height.  At some point there will be changes to boot binding angles to worry about but I've seen differences in toe/heel height of 8mm so would think you are ok until then and I doubt you'll need to consider having the toe 8mm higher than the heel.

Sorry just thought of a concern.  As you move into negative binding delta (toe higher than heel) you start to reduce the boot toe lug/binding clearance.  At some point it is possible to introduce extra friction into the system.  I can do quick calculations if necessary.

Yes,  this is exactly what I'm trying to accomplish.  Just removing the lifter under the binding heel made a noticeable improvement,  but I suspect the fwd lean of the boot is still forcing me more forward than is natural.  I may be wrong,  but I'd like to try it.

 

Dave,  I'm not sure I understand your question.  I guess what I wish I could do is modify the fwd lean angle of the boot cuff.  Since that looks like a difficult modification,  I was hoping to "cheat" a bit by effectively tilting the footbed forward to gain a couple of degrees relative to the boot cuff.  I guess I'll just have to try it to see if it works.

 

Thanks, guys.

I'm not certain I agree that increasing boot ramp is the same as decreasing forward lean, but do agree that it decreases dorsiflexion angle.  If you are having problems assuming the position you want due to tightness in the achilles and gastroc then increasing ramp may help.

the boot has more F lean then you want, correct?

So where on your leg is it pushing you too far forward?   back of the calf? (almost a pinch) or from the ankle joint (the whole back of the leg is being pushed)?
