This is an actual computer test of a runner taken at one of our marathon expos, shown at about 1/30th the normal speed. It demonstrates the comparison of motion of the foot (this foot belongs to a high arched supinator—who still pronates) as it steps across a pressure plate designed to capture the forces generated, first in the barefoot mode, the same foot with the individuals own "traditional" orthotic and lastly that foot wearing a prescriptive silicone dynamic orthotic.

Every foot has a certain amount of imbalance to it (seen in the barefoot mode as colors, red is high, blue is low).

What you are seeing, is that the fluid is filling in the arch of the foot so that there is more contact surface of the foot on the floor, yet all the important “contact” points of the foot are also making contact and are “stable” on the floor.

In this way the fluid is “hydraulically” pushing the structure of the foot into proper biomechanical/alignment position.

With the Silicone Dynamic Orthotic, the foot is in its most efficient alignment (optimal position). Balance is regained throughout the entire lower extremity, reversing years of accumulated inflammation and pain in knees, hips and low back.
