|after months of intermitent back pain, i went to the doctor (chiropractor). he did some acupuncture and tolme that, maybe, the pain is caused by a difference in length between right and left leg.. he noticed a difference in muscle size of lower legs. i'll do some x rays and probably wear some orthothics. i've suspected this cause i have difficulty in setting saddle height: if it's good on one leg, it's bad on the other. |
is there any cycling specialized orthothics, i mean something for shoes or pedal systems that would compensate for leg length difference?

|how different crank lengths? say 170mm on one side, 172.5mm on other just for example? YOu can get old used cranksets on ebay fairly cheap if you watch..|

|It should be fairly easy to add a shim under the cleat of the shorter leg. I use some wedge shaped shims under my cleats to add some camber so I know it's not too difficult.
As far as orthotics go, they are difficult to fit into shoes which limits their usefullness for cycling.
|Where did you get the shim?||Eug|

|I'm wondering if a slight angle change (side tilt) would help my medial knee pain.|
|I use these http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXE953&P=0
Most good hobby stores that sell RC airplane hardware have them. Just trim to size and install under the cleat. I use the 3 degree plates with good results.
There used to be cycling specific wedges available called Big Meat wedges (or something to this effect). They were fairly expensive though ($20 a set). The Ernst stuff is far cheaper and seems to work well so I just stuck with them.

Just trim the shape to fit your cleat. I use the 3 deg. shims.

|I had the same problem. I fixed it with a kit from speedplay for use with my zero pedals. You may also want to check out rocket7.com for carbon fiber inserts or custom shoes. Just don't forget to only correct for half the lenght.|

|What worked for me was lowering my saddle a couple of mm's in order to compensate for the lower leg. I wear over the counter orthotics, Superfeet green capsules seem to work for me. Or Spenco 3/4 arch supports. You can heat the Spenco inserts in hot water to soften them, then put them in your shoes and they will mold to your foot. I guess it all depends on how much the leg difference is. It might be worth a visit to a podiatrist who knows what he is doing....|| |
