Hamon

It is designed to create an intentionally wobbly footing so that even when the person jiggles their legs, the sway of the upper body is not noticeable. In addition, the surface where the feet rest has ripple-shaped (hamon) bumps and dips so that the feet receive more sensory information. By stimulating both the instability of the footing and the sensation of the soles of the feet, it was made to add stimulation to both proprioception and the vestibular sense.
