The biomechanics of your walk and standing stance are studied using sensors placed on the soles of the feet. This data is translated into a "picture" in HD, highlighting the instabilities in your walk and pinpointing the places where your feet carry too much wieght, causing foot pain, calluses, and potentially ulcers. A few steps away from the gait analysis room is a state-of-the-art machine that makes an imprint of the sole of each foot, forming a 3D view of your arch on the screen above it.
