But in my case the discrepancy was caught as it was developing (one leg mostly stopped growing after an accident when i was a teenager). If you have been walking around uncorrected for a long time, I guess a full correction might cause problems.
I have a lifted set of shoes for clipless pedals. It was not easy to find someone who could do it, though. It is a bit more involved than just sticking a lift on.
Becuase most of my discrepancy is above the knee, it took a lot of experimentation to figure out what works best. For me it ended up being a 40mm lift (as measured under the cleat), and a 5mm difference in crank lengths. Makes buying new cranks a PITA.
yeah for my situation the 50% thing may have to do with it going for so long without being corrected
