Knock-kneed and underedged- help with canting

post #1 of 7
Thread Starter 
I have an unusual canting question here. I want to experiment with some trial and error under boot canting, I guess with duct tape or whatever else someone can recommend. I am currently on a Nordica Beast 12 boot with great instaprint custom footbeds made by a superb fitter. I am underedged and have always had all of the symptoms, including catching outside edges for quite a while. Also, a tecscan machine showed my weight disproportionally on my little toe boot side, but lucky for me very symmetric right and left. What makes this unusual is that I am actually quite knock-kneed, and have my boot cuffs properly adjusted inward to match my tibial curvature. From my understanding reading here and in other places, knock knees are typically overedged, rather than on their outside edges.

I am not sure why I do not fit the typical picture. My ankles do evert very easily and are much more limited with inversion. Additionally, when I stand barefooted or in sneakers, I tend to favor weighting the outside of my foot rather than under the first metatarsal head like normal, and my sneakers tend to wear on the outside first (however I have never been considered an oversupinator.)

Given this picture, if I wanted to start experimenting with canting, where should I build up under the boot. I am under the impression that for knock-knees, normally the inside bid toe side is built up to move the knee into alignment, but this would exacerbate my difficulty pressuring the inside edge. However, If I build up the outside edge, wouldn’t this make my knock kneed position worse? I am really unsure how to approach this properly. Any and all advice is appreciated.

According to Witherell, you are a rare case where the cuff can be used to perform canting. He recommends moving the cuff to the outside to align the knee and reduce supination.

As far as canting is concerned, going thick side in usually makes pressuring the inside edge easier as the edge will engage with less knee angulation.

try moving the cuff around and see if that help

dimes with duct tape are 1mm thick. shim them under the boot over the AFD.

You really should experiment as much as possible.

I'm knockneed also and, in some situations, I also overweight the outside of my feet. However, I believe that comes from years of subconsciously compensating for a knockneed stance when walking or casual skiing.

My concern was in difficult ski situations where this compensation method would disappear; my natural knockneed stance would return with excessive inside edge pressure.

I never had any success with cuff adjustment. Finally, I just bought the canted heel / toe lugs for my Lange boots that elevate the inside sole. I noticed an immediate, natural improvement in my skiing. Much quicker, precise edge changes in difficult situations.

LSS, some of your other symptoms may have resulted from years of overcompensating but that overcompensating might be overriden by natural stance/instinct in tough situations. Don't necessarily go by the wear pattern of your street shoes' soles!

Thanks for all the help. So the quick and dirty approach here would be to move the cuff back outside a little and see what happens. Easy enough, so I'll try that first. Then maybe add some tape inside if I'm not thrilled with the results.

what srhav has to say is actually very interesting. I have often had a hard time figuring out if I am underedged or overedged until I really concentrated on figuring out how my skis were running. I also have had occasional symptoms of both problems, ie while typically I tend to catch outside edges, I have also experienced quite a bit of railing the outside ski at times. Truthfully, pilot error may be to blame here (still bank inside a little too much sometimes) but I wonder if there is any merit to the thought that when the situation gets tough, my compensation methods break down. Interesting.

Just to add something that may clarify the situation, I have a mild Morton's foot symmetrically. This is not a Mortons neuroma, but rather when the 1st Metatarsal is shorter than the 2nd metatarsal (it can lead to the neuroma in some cases, but I have never had this problem at all.) If I remember correctly, some people with this bone configuration tend to weight their outer foot as a natural compensation mechanism for the feeling of rolling heavily to the shorter 1st met head when running. Although my foot does not severely overpronate, I do think I have developed a natural compensation for this, explaining my stance on the outside of the foot. However, what I do not know at all is whether this would even be relevant in a rigid ski boot.

How many degrees are the new lange lugs canted?
post #7 of 7
1.5 either in or out.

Again, I canted "out"; thus inside sole is higher to force knees toward a more centered position. I believe this is the typical solution for knockneed (notwithstanding any other complications) though degree may vary.

I actually thought I wanted the cant to increase the outside sole height; to cant in. I thought that it might be preferable so that I would get a flat ski when in a natural knockneed stance and with no compensation.

However, bootfitter convinced me to go "out" and I like how it works. The canted lugs are crude but a quick (though $50 experiment)
