The explanation I got from my doctor was that one shouldn't fix posture problems by raising the inner part of the insoles a random amount because all that achieves is making you run "weird", putting pressure in the wrong part of the articulation and damaging the ligaments that keep the knee in place. The actual solution involved muscle development exercises, ripping out the insoles of those shoes to achieve a flat base and replacing them with custom-made ones, knee pads with metallic inserts, and a two-year training plan.
