My question is this, if you have a rearfoot valguswhen and by how much is it appropriate to post the rearfoot and by how many degrees. Thinking about the structural forefoot patho;ogies that arise from this foot type it would seem that the earleir the intervention ther more chance of reducing the chance of future structural pathology developing. Obviuosly great caution would be taken when attempting to bring about functional changes with consideration to the affect that bring about these changes would have on other areas of the kinetic chain.

So my question is,
1. would supplying rearfoot posting to a young person with rearfoot valgus be appropriate as this would reduce the pronation they would experience, and therefore the destructive forces occuring in the forefoot .
2. If it is approppriate to post the rearfoot, then by how much. If, say the neutral calcaneal stance was 10 degrees valgus and 15 degrees relaxed stance, then would you post the rearfoot to 10 degtrees and thereby have the sub talar joint in the neutral positiion when in relaxed stance. this would, of course, reduce the degree of pronation but would this be enough to reduce the forces acting upon the forefoot enough to prevent pathological changes. And, if not then would it be appropriate to post the fearfoot to, for example neutral. And my quesation is , would this be the right thing to do, or would the result of doing this result in a foot that no longer overpronated but as a result of the degree of posting required to do this would result in a sub talar joint that was excessively inverted in relaxed stance and therefore laterally unstable.
