I found that my legs are pretty close to the same length .03 difference is all. I was using shims and I really don’t know if I need too. I’ve been reading that a lot of fitters use them. So I’m thinking that is for foot cant and they say it’s usually for one foot. Which foot do you put the shim, the side that chafing or the other side?
Thanks for any replies

Also how many people do you know that don’t use shims at all?

I have some sort of hip imbalance such that the right knee tends to brush the top tube. I use a shim under the cleat and in addition some extra support under the arch in the shoe. No pain or even discomfort.

Do you use the shim under the same side ?

I think I misread that and you did put the shim under your right cleat. Thanks for the reply.

I don't use shims and my son isn't using shims. Since it's not a topic that comes up in casual conversation, I don't expect to know any others. Didn't know I was expected to use them. I thought they were for if you are having issues that might be related to how your foot/shoe sits on the pedal. And also for some shoes that the cleat sits too deep in the sole to engage the pedal properly.

What am I missing?

I use spd on my road bike. So is shimming more prevalent on spd-sl and other types considered road cleats?

I have been using shims (LeMond wedges) for many years.
I had chafing on my right sit bone area from the saddle so I shimmed the right side cleat in conjunction with correcting for vagus.
The chafing improved. I also tried turning the saddle nose slightly to the right side, but I'm not sure if this improved the chaffing.
