This plate is rigidly setract when the toe and heel portions are cured in the socket 14 of the heel portion by swung in opposite directions relative to each means of Suitable fastenings 23, and it has othe z curved slots 24 and 25 arranged concentric With the above and other objects in view with the curve 17, and which slots slidably the present invention consists in the combiembrace pins 26 and 27 respectively, whereby nation and arrangement of parts hereinthe swinging plate, when swung by the heel after more fully described, illustrated in the portion 11, moves in an are parallel with the accompanying drawings, and particularly arc of the curvature 17.
