People with flat feet are unable to stride as they should and must alter the way they
step. The problem with flat feet is that at mid-stance, the inside edge of the foot and
big toe are slightly off the ground, making them an ineffective lever to push-off. Flat feet
must roll inward to be entirely on the ground before becoming an effective lever to
push or toe-off.
This problem is compounded because the foot's ligaments and muscles which
normally maintain the arch, fail. The arch collapses and the foot flattens out
causing the foot to roll inward excessively (over-pronate). This improper
biomechanical action is the cause for most lower back, hip, leg, knee, ankle and
arch pain suffered by people with flat feet. Many people with low arches or
flat feet are unable to stand, walk or run as they should, because the foot's ligaments,
muscles and skeletal system which normally maintain an arch, fail.
ARCH SUPPORTS DO NOT STOP FLAT FOOT OVER-PRONATION
Past attempts to relieve the pain, suffering and injuries related to low arches or flat
feet have failed because they concentrated only on the heel or arch. Arch supports work for
people with normal or high arches, but not for people with low arches or flat feet.
It sounds logical that if the arch collapses, it can be helped by propping it
up with an arch support. Unfortunately arch supports can't solve the problem,
because they do not prevent flat feet from over-pronating and therefore don't
stop the destructive forces.
Arch supports are only effective while they are bearing weight when the foot
is in complete contact with the ground.
Once the heel comes off the
ground, weight moves to the forefoot. No longer bearing weight, arch supports no
longer function and the foot is allowed to over-pronate.
