Abstract: A walking aid device is disclosed which permits a user to increase his stride without requiring auxiliary elements that slide or roll, and makes use only of the muscles normally used in walking. The device has a lower part-circular base made of non-skid material and extending over an angular sector corresponding to a subtending chord of length equal to 1.5 times its radius of curvature, and a board fixed across the base equidistantly from the ends of the base, to receive the users foot. The board is equal in length to the radius of curvature of the base.
