Heel lifts and quad burning?

post #1 of 8
Thread Starter 
I recently saw a bootfitter and he put heel lifts under my liners. I can't believe what a difference they made--I am so much more balanced on the kind of steeper or bumpier slopes I have been having a hard time with (I only started skiing last year).

But, my quads got soooo tired using them. The fitter had made a comment about how these are going to put me forward onto my quads but I didn't really think about it at the time. I had to call it quits early today because they were just trashed. Now, I learned on this board that if your quads are burning, you are too much in the back seat. I wasn't having problems keeping my weight over my feet anyway (according to instructors) and now I feel especially forward with the wedges. So what's going on? Am I doing something wrong?

what boot are you in? the forward lean of the cuff combined with the heel lift and the ramp angel of the boot could be putting you too far forward, your bodies solution is to compensate by shifting the weight into the back seat

CEM is moving in the right direction. So along with the question of which boot you are in, could you give us a little more to work with.

1.Do you have any support under your foot like a custom footbed custom or trim to fit?
2. How much room do you have when shell sized? What is the shell size in mm?
3. Height, weight, age, fitness level, skiing level, street shoe size, description of footshape (narrow, wide, high/low instep, high/low arch, etc)?
4. Ankle flexibility, ( none, limited, low, normal, excessive )
5. What ski and binding are you using?
6. Do you know what size heel lift was installed?
7. Is there a spoiler shim against your calf?

Any help that you can give to better describe your situation will net you a better answer.

Hi Christy

In addition to the questions Colin posted, the quad overuse issue could also be caused by additional equipment geometry and body physiology parameters.

1) What is the shape and size of your calf muscles? (big/small/high/low)
2) Has a bootfitter evaluated your range of motion at the ankle?
3) What binding is mounted on your ski? (stand height differential)

Some possible solutions:

1) decreasing upper cuff forward lean (remove spoilers)
2) using a binding with a more level stand height
3) toe lift
4) tongue shimming
5) stiffer flex of boot

Wow. It sounds like another trip to the fitter, or at least a conversation, is in order. Thanks for the willingness to help. The thing I don't get is how I could be in the backseat. It didn't feel like it at all. One problem I used to have was when things got steeper and bumpier, or when my legs got tired at the end of the day, I would start leaning back. The lifts made it impossible for me to do that--a couple times I sort of got bounced back there and it was amazingly easy to recover and get forward again. With these lifts I skied better than I have ever skied, no question about it.

1. I have Superfeet trim to fit insoles--the bootfitter wants me in custom but at $185, I'm more than a bit hesitant. I've used Superfeet for years in my hiking boots and they treat me well even on long backpacking trips with heavy loads.
2. No idea about shell size.
3. 5'4", 118, age 39, I'm a low intermediate, fitness level good (cardio and nautilus 3x per week, Pilates 2x), shoe size 7.5, I have a high arch but I've never had anyone tell me my feet have any other issues (not wide or narrow, etc).
4. No idea about ankle flexibility.
5. Nordica Olympia Drives with Marker bindings that have a 3mm differential. Nordica Beast X10 boots.
6. I don't know the size of the lift.
7. I don't even know what a spoiler shim is!
Cantman, I have no idea how to describe my calf muscles. I am a slender person but you can see muscle. The fitter did talk about my ankles but I don't remember if he evaluated their range specifically.

My bootfitter thinks that now I am perfectly aligned in my boots, but that my bindings (they are 3 mm higher in the heel) are pitching me too far forward, so I'm leaning back to compensate (thus the quad burning). So he suggested getting my bindings flattened.

Sounds like a good place to start.

Just a note so that you know, it is very possible to have a heel lift and be in the back seat. As previously alluded to the affect of excess ramp can be to sit back in order to feel balanced.

Not saying this is happening only that heel lifts do not automatically cause staying forward.
