1 Claim. (Ci. Sid-35)
This invention is directed at an improved turnable heel
and sole construction, for a shoe.
According to the invention there is provided a heel or
sole body for a shoe made of rubber, plastic, ?ber or com 10
position material. The body is provided with a cavity
normal wear. This screw can be loosened and the ring
can be turned by ?nger pressure on core 34 so that when
the outer portion of the ring exposed beyond the ?nger
portions 25 of the heel body is worn, the ring can be
turned around to expose a fresh unworn portion for
renewing the life of the heel. A thin metal foil sheet 23
or a rubber sheet can be inserted between heel structure
20 and heel base 42, to waterproof the heel. The sheet 23
is formed with a central opening 27, and may be fastened
for receiving a turnable rubber member adapted to be
secured in place on a shoe by a core or plug having
tapered sides. In one ‘form of the invention, the core
itself is adapted to be turned to equalize wear thereon.
The outer surfaces of the members constituting the sole
or heel may be ribbed or corrugated.
It is therefore one object of the invention to provide a
heel or sole body ‘for a shoe having a cavity adapted to
to the ring 26 by cement or the like.
The nails 33 extend through the opening 27 of the sheet
23 so that the core 34 can be rotated slightly. A screw
29 extends through the center of the core and into the
base 42 and may be set upon to hold the core in adjusted
plurality of turnable rings and cores having tapered walls.
For further comprehension of the invention, and of the
objects and advantages thereof, reference will be had to
the appended claim.
The structure of heel 22a in FIGS. 5 and 6 is similar to
that of structure 20 except that the ring 26a and core 3:4a
receive ‘an annular ring, the ring having an inner tapered 20 have outer ribbed or corrugated surfaces '33, 35, respec
tively. Otherwise the ring and core have the same struc
wall adapted to abut a mating tapered wall of a circular
ture as that of members 26 and 34 and corresponding
core whch ?ts within the ring and holds it on a shoe.

A further object is to provide a sole or heel structure
