The next joint affected is the hip. Not necessarily hip pain, but the spine compensates for any abnormal alignment or positioning of the hip, and low back fatigue or pain is the result.
The neck, which is the cervical spine, is at the end of the kinetic chain. Pain from the distal influence of the feet is less likely than with knee pain, but it can happen. For example, leg length difference over time will abnormally curve the entire spine.
The feet are similar to the roots of a tree; what happens down at the ground changes everything above it. Therefore, Podiatrist-prescribed Orthotics can correct malalignment from the bottom up and improperly-made insoles or footwear can cause malalignment where there was none, and cause damage where there should not be.
