Help with External Tibial Rotation and Bike Fit

Hi all,Has anyone has any problems with external tibial/foot rotation and bike fit? I ask because I have been having discomfort riding my bike for a while now and I can't quite figure it out. Based on my natural position/alignment it appears my right foot/tibia rotate outward a bit (below the knee, not on bike) and when I'm clipped in on the bike this puts a stress on my entire right leg that I can't get rid of no matter what I do. I ride a Trek Emonda with SPD Pedals. I have tried numerous cleat positions, seat heights, etc. but can't seem to find a way to ride comfortably as it always feels like my foot is in an unnatural position (turned too far inward). I'm currently seeing a new PT to see if I can get some help but fear that since this seems anatomic it might not be the ultimate answer. Maybe some cycling specific orthotics? Other thoughts?

Thanks,

Dustin

My inclination is that if the leg wants to turn outward, then let it. But you may be able to check this out in advance with plain flat pedals. If you no longer have plain pedals, get some and ride them around for a few days then see how your leg feels.

Eh? SPD cleats/pedals usually have about a 7° float. Simply turn the cleat on the shoe until your leg is comfortable and you're not coming up against the end of the float. When your foot is in its natural position, you still should be able to turn it in both directions a few degrees. You don't need to put on flats to see what your foot wants to do, you already know that. If you're using MTB shoes, you may need to carve on the cleats a bit to get the cleats right, but usually not.

Zero float cleats are made, but are rare.

Yup.

Mount the cleat at an angle that accommodates this movement/position. Don't try to correct it with the bike cleat, or you are going to be in a world of hurt.

I have not tried it, but Time pedals offer lateral float.
