leg length discrepancy: anyone ever set their bindings a bit different per leg to adjust for such?

post #1 of 13
Thread Starter 

I have a 2/3" leg length difference (right is ''longer'')...unsure if it stems from hips or lower back or whatever....but I know it exist as when I get my pants hemmed  or running or even cycling (the right leg is the longer one) and i find the right foot will often be 2" further forward on pedal...a recent physio confirmed it too.

 

I was told that only on racing ski boots can a proper shim be put on to make up such difference for length (vs the surface area and soles of our more common rec boots), so was wondering about moving my right binding up a cm or two (in baby steps) to try things out. I find there is a difference in feeling the entire left foot vs right foot on my skis when turning.

 

anyone out there have the same issue and has experimented with such binding placement differences per leg?

I guess it's better to correct on the boot than the riser plates.

 

Technica Agent model boots are a race shell with a recreational (warm and soft) liner. you could use that set up and glue/screw on your shims. yeah, I would do it on the boots and then you're set. 

 

race shell soles are pretty basic=plastic one piece, no removable replaceable parts. grind them any way you want. I put the vibram soles for alpine bindings on my Agents.

You were told wrong.  Pretty much any boot can be plated and routed to make up your leg length difference.  It's a piece of cake for anyone boot fitter who has the right tools.  I would suggest having your alignment assessed at the same time so you could kill two birds with one stone.

 

good luck

well by a reputable ski shop I was told that given the boots that i have (dalbello krpyton cross) if they were to cut into the base it would cut into some mechanism in the sole or near the heel piece.

 

so now I'm confused, esp with your reply (thanks btw)

I have exactly the same problem, same leg.  Greg Hoffman installed a 3mm plate on the bottom of my left boot and routered the boot back to DIN spec.  I see no reason you couldn't do that on any boot, it's not cutting the long leg boot, but adding to the short leg one.

 

He said he would only go 1/2 the LL discrepancy.  Also have lifts in the boots.

I am sorry they gave you misinformation.  I am a Dalbello dealer myself and I have planed and plated many Kryptons without any problems.

 

Also concur with Hoffman that we generally make up 1/2 the discrepancy length.

Equipment handling concerns out of the way, let's talk about this "apparent" LLD.  I take it from your post that you actually haven't been evaluated by a doctor for the LLD (what's "a physio confirmed it"?).  No doctor will give you an LLD diagnosis as 2/3".  So I'm questioning what's actually been investigated and diagnosed.

 

You really need to see a doctor (podiatrist or ortho) and have the LLD quantified so that any orthotics or modifications to your ski gear are correct.  Having an LLD properly diagnosed to a high degree of accuracy requires a Cat-scan and a couple x-rays.  I have had this done and IMHO it is the right step for handling the problem for not only your skiing, but your life.

I have a similar problem. On really simple runs, where I use no edgeing at all, the ski on the shorter leg
occasionally starts sideways vibrations, that get severe if I do not take care of them by edgeing.
Long time ago, before I bought modern curved skis, I ordered at some ski shop in Arosa, Switzerland,a platform beneath
the bindings. The owner of the shop took it very seriously, contacted some ski and bindings manufacturers, and in less
than a week for some 40 SF built a platform from a piece of plastic that is used for display of bindings in the store.
The manufacturer of the bindings provided longer bolts, otherwice similar to the original ones. Everything was perfect.
When I switched to curved skis,I did not raise the bindings. I fell may be twice in every three years because of this,
but it did not buzer me too much. The last season (3 weeks ago) I had a very bad crash, I think because of this same problem.
I am going to build a platform beneath the binding of the shorter leg, the same way the guy in Switzerland did. The only
problem is to find the bolts similar to the existing, but longer.

Are you saying two thirds of an inch or 2 to 3 inches?

John J: leg length diff is 2/3 of ONE INCH....(jeez...can't imagine the discomfort and inconvenience 2-3" would cause, if that did exist)

 

Update I went to see Brian Campbell at Top Shelf Sports in Whistler.....he said an allignment would be a good start...a suggestion was to either shim one boot and/or shave down the sole on the 'longer' legged boot.... and that often when he places some rubber SBS like wedges at various points of the boot often his cust find that is sufficient.....

.....like myself, Brian was a bit dubious of orthos and cat scans or such who could accurately 'measure' the origins of leg length, given it's pretty subjective too

ie from what part of musculature or skeletal does my leg length diff really originate from?...but this said, Noodler I might investigate further as per your post above #7.

 

I will probably go for their custom liners (like Surefeet, they're $$ at $450, but if my boots can fit better and such that's a good investment).

Not subjective at all; consensus anthropometric landmarks for over a half century. Suggest "Methods in Human Growth Research," Hauspie, Cameron, and Molinari, Cambridge, 2002. Keep in mind that apparent visual leg length can be influenced by trunk posture, canting of hips, so on. So measurement needs to be done by someone who knows what they're doing; your average MD may not even have the right equipment to detect differences of a cm or so.

 I've mostly dealt with this in ski boots, although my foot doctor did order my regular orthotics to be built up a few mm last summer. In regular shoes, there is a limit to what you can do, no matter what the discrepancy, otherwise my foot just won't fit into the shoe. (High instep doesn't help, there isn't a lot of room, and my foot goes numb.)

 

Anyway, the boot fitters seem to spend a lot of time looking at my kneecaps and where they align, if that's helpful to anyone. This last pair of boots was built a little bit both on the outside (thin plastic on bottom of boot) and on the inside (bottom of the orthotic). FYI, YMMV, ETC.. I don't think it's a really exact science in reality, as they've all told me that they only increase things part way anyway, and don't try to make up the whole difference. I've heard that from two boot guys, my doctor, and my physio, so I guess I believe it.
