How do you deal with different leg lengths?(12 posts)

Do you use different crank lengths, a wedge or do you just sit lopsided?

I think they have wedges that you can put in your shoes that will help take care of that as well.

I'm a chiropractor and work with leg length inequality issues daily. My first question is how much of a leg length difference to you have? A small difference might be an issue in walking but not much of an issue with cycling because one could compensate a bit at the ankle.

Most wedges I've seen are put in the heel of the shoe and are of benefit only when you are walking. Since the wedge is not put under the forefoot, it would not help much for cycling. There is probably not enogh room to put a wedge inside the shoe under your forefoot. I am not aware of a commercial product to compensate for leg length inequality for cyclists.

I would find a piece of firm plastic or similar material then shape and drill it to fit between your cleat and shoe. You will probably have to find some longer bolts as well. Let us know what you find or create.

I guess they are shims that go under your cleat.

I have a freind who used some type of wedge in hsh shoes to correct this problem.

That's great! That's just what the doctor ordered. I'll be getting some more info on those shims. I want to advertise and start working with cyclists more. Those shims look like great tools to help with difficult fits.
Yes, LeWedge...Anaerobic_Nut

The LeWedge system is the way to go, since you can get wedges for both MTN and Road cleats. Be sure to adjust for only half of the leg difference. I'd recommend having a PT or someone with a good bike fit experience measure this for you, otherwise you'll set yourself up for more problems later...I've been there.

I have a shim under my cleat and an orthotic, which together make up the one half inch difference in leg length for me.

where did you get the shim? did you make it or buy it and where did you buy it from?

thanks

I cut some plastic shims out of a milk jug.Sintesi

I have the same problem. But not knowing the extent of your problem and instead of making a "deficiency specific" recommendation, I'll just try to give the following information for your consideration:

VARIABLES:
1) length descrepancy
2) how you have naturally compensated (skeletal structure) for the discrepancy over time.
3) how you have mechanically compensated (bike seat or cleat adjustment) for the discrepancy.

Things to consider:
1)Tapered shims on cleats
2)Flat shims on cleats
3)Flat (inside)shoe padding
4)Custom orthotics
5)Slight (forward/rearward)adjustment of your shoe cleats. (Be careful and do it incrementally!!)

Personal observations/comments:
1)Tapered shims "forces" you to pedal on an angle.
2)Depending on how much you have to compensate you may have some mechanical issue.
3)Flat (1/8")inside shoe padding underneath the "of the shelf"( Dr Scholl's) orthotics worked best for me.
4)(Expensive)Custom orthotics did not work well because it was made to compensate for the 1/4" discrepancy, but my body "naturally compensated" to some degree and 1/8" shimming took care of the rest.
5)Again, depending on how bad the discrepancy this might work. For me it was okay for short rides (<50mi), past that I start feeling some discomfort.

* Actual measured discrepancy does not necessarily translate to actual size "shim" to compensate the discrepancy because your body have compensated to a certain extent to your deformation.

* Setting your seat(height or forward/backward) adjustment to slightly favor towards your short leg might work too. Be careful not to overdo this as you might end up having knee problems.

*what seem to work on intermediate rides (<50mi) does not work on Century rides.

Have fun experimenting.

If you use speedplay pedals, you can buy shims in 3mm thicknesses. Just the ticket for me.
