Abstract
A massaging foot pad can be installed in a shoe or on a sandal. It includes resilient protrusions arranged on top of a sheet. The protrusions are elongated in a horizontal direction, and slanted in an orthogonal direction, so that they each include an upper side facing obliquely upwardly, and a lower side facing obliquely downwardly. In one embodiment the protrusions include a notch arranged on a lower side, and a large rounded tip. In another embodiment, the protrusions include a large rounded tip and a narrow base. In still another embodiment, the protrusions include a thin tip, a wide base, and a notch on the lower side. In yet another embodiment, the protrusions include a convex upper side and a convex lower side. In all embodiments, the protrusions easily bend in the direction of slanting when pressed by a foot during the downward movement of a walking step, so that they rub horizontally across the bottom of the foot. When the foot is lifted during the upward movement of the walking step, the protrusions rebound in the opposite direction, so that they rub horizontally across the bottom of the foot backwardly. The to-and-fro movement of the protrusions massage the bottom of the foot as the user walks.
