I ask this because I have flat feet (old injury as a kid that never healed correctly and has gotten progressively worse over time) and experience cramping in the lower leg region quite often (calf cramps and shin splints). My left leg is flatter than the other and thus my right leg works harder than the left. My right calf tends to cramp earlier but left side gets shin splints more. I've found adding some "shims" to support my feet (more on the left side) allows more, even applications of power and lowers occurrences on either side.
I'm asian, so we do tend to have mild flat feet, although it's never really been much of an issue. The fitter did put shims on both my cleats. I believe my knees had a tendency to bend in, especially at the bottom of my stroke. The shims made my knees track a bit better, but I don't believe it fully made it vertical.
