Haven't tried, but assuming that 20 degrees of
inversion would not be obtained unless the foot has a
really weak supanation resistance and a perpendicular
RSCP

I would like to suggest that if the foot fits into the
'normal' ROM and has 20 degrees to 10 degrees then
the wedge would invert their rear-foot 20 degrees less
the amount of RSCP eversion.

This is dependant on alot of things. Peroneal
tightness, STJ ROM, ankle ROM, gastroc/soleal complex
tightness.

Be interested to read Nigg's article regarding this.
Anyone got a refernce?
