If the body was a rigid structure that required nothing but a solid base of support, the supinated foot would be ideal. However, as soon as we walk or run the foot must function as a mobile adaptor, so that shock can be absorbed. If a foot is overly supinated, it usually tends to be rigid and is not capable of undergoing adequate pronation (to absorb shock). Unlike pronated feet which can be made more stable by an orthotic, supinated feet cannot be easily made more flexible. The lack of proper shock absorption and excessive tilting to the outside can result in frequent ankle sprains, peroneal tendonitis, tailor’s bunions (on the 5th toe), excessive callousing on the outside of the foot, knee and back pain (due to lack of shock absorption) and iliotibial band syndrome.
