I was diagnosed a few weeks ago by a PT with unequal legs. So far I have been wearing a 12mm heel shim, not under the ball so it doesn't help riding but I am becoming increasingly aware of the discrepancy while riding. But walking/standing? Wow! I never knew I was standing on a tipped floor! For 60 years!
I think I will go out to the shop right now and make a 1/4" shim. See what that does (besides kill cleats and floors).
