Your feet are the foundation of your body. They support you when you stand, walk, or run. They help protect your spine, bones and soft tissues by absorbing the impact of movement.
When walking the arches of your feet function to both absorb the shock of impacting the ground, and spring the body forward into the next step.
Your feet perform their job best when all their muscles, arches, and bones are in their ideal stable positions.
The foot is constructed with three arches which, when properly maintained, give exceptional supportive strength.
These three arches form a supporting vault that distributes the weight of the body across the front and back of the foot.
If there is compromise of one arch in the foot, the other arches must compensate and are subject to additional stresses, which usually lead to further compromise.
It’s a chain reaction.
To completely treat knee, hip, pelvis or back pain, the state of the feet can not be ignored. The feet are the basis of the kenetic chain that all of these structures are part. Faulty foot mechanics compromises arch mechanics, which transfers the load to these higher structures.
Arch stabilizers are shoe inserts that stabilize and balance the arches of the feet. They enhance your body’s performance by helping the arches to maintain their shape and function. This helps to reduce unwanted stress on the body.
Wearing arch stabilizers inside your shoes is similar to placing a shim beneath the leg of a wobbly table: it adds support to eliminate unwanted motion in the entire structure.
Foot pronation describes the rotation of the foot downward and inward. It is a normal motion that occurs when walking.
However, if pronation occurs excessively, it can cause global postural problems. The major cause of over-pronation is a decrease in the arch height. The rotation of the foot leads to the bones of the leg (tibia and femur) also inwardly rotating.
Excessive rotation of the leg will cause a torque stress on the knee as well as twisting of the pelvis and spine.
If the pronation is more prevalent on one side, there can be a resultant unleveling of the pelvis and a functional scoliosis.
Tilting of the pelvis places tension on muscles and connective tissues; this can eventually lead to chronic back problems.
