are two ways to reduce hyperpronation. The most natural process is
referred to a "Janda" or a "Small Foot" exercise. Dr. Vladimir Janda
devised an exercise that can most simply be described as picking up a towel from
the floor with your feet (but without curling your toes). Regular Janda
exercise and a consciousness about using these muscles when you walk will
strengthen your feet. The caveat is that consciously using these muscles
is un-natural, and hard to do.
Traditional orthotics push your foot toward a less hyperpronated static position. While that works well while you are standing still, as soon as you start walking your foot will still hyperpronate as you move off the orthotics toward toe-off. Bottom line: Rigid or semi rigid arch supports and heel shims do not really work very well, are often uncomfortable and require special or larger shoes.
Why Posture Control Insoles work better
Posture Control Insoles® work better because they effectively reduce hyperpronation through the full gait cycle. When the first metatarsal and big toe senses ground contact they naturally cause muscle contractions to counteract the ground force. I.E. the first metatarsal and big toe will exert counter pressure against the ground. The problem is that a Rothbart's Foot Structure has an elevated first metatarsal so sensing ground contact occurs too late in the gait cycle. Posture Control Insoles® are essentially a timing device providing an earlier sensory input to the first metatarsal and big toe resulting in the foot mowing toward supination.
For most people, Posture Control Insoles® reduce hyperpronation significantly without the use of arch supports. People who have flexible flat feet or who suffer from Plantar Faciitis benefit from a modest amount of arch support.
