One of the objects of my invention is to pro date and tightly hold said raised portion. A recess 22 in the concave wall of said tread por tion 20 receives lever I8 when the latter is in depressed or engaging position. The clamp performs two functions in this con struction: by virtue of its gripping pressure it artisan for such replacement. holds tread member I I snugly against heel mem Another object is the provision of a tread mem ber I0, and .by Virtue of its rounded but non ber for heels which is interchangeable between circular shape it prevents rotary movement of the right and left shoes, thereby rendering it possible to equalize the normally unequal wear 10 said tread member about its vertical axis. The embodiment shown in Figs. 4 and 5 is of heel tread members. identical with the ?rst embodiment except in A further object is the provision of a tread two respects: The recess 25, clamp 26 and raised member for heels which carries no metal fasten portion 21 are circular rather than non-circular ing devices such as nails which can protrude through the wearing surface of the tread mem_ 15 in shape, and a plurality of inwardly projecting lugs or teeth 28 on the side walls of the clamp her when the latter is worn down. enter correspondingly shaped and spaced re Other objects will become apparent from a reading of the speci?cation. cesses 29 in the side of raised portion 21. In Two preferred embodiments of the invention this embodiment, these teeth prevent rotary are illustrated in the accompanying drawing in 20 movement of the tread member relative to the which— ' heel.

For example, the clamp may be provided with tread member of the said embodiment; other non-circular shapes. The particular shape Fig. 4 is a horizontal section of the second of is not important as long as it is non-circular said embodiments on the line 4—4 of Fig. 5; and Fig. 5 is a longitudinal vertical section of 30 and without sharp corners around which it would be dif?cult to draw wire H.
