at It‘ on its forward edge or wall, the other edges
being vertical or substantially so. The undercut
I5 corresponds in angle to the bevel I4 on the
shoe insole.
The insert I5 is spaced inwardly
from the outer edges of the heel. At the end of
the insert 55 opposite the undercut portion I6 is
provided an attachment mechanism. This com

tion, the cut-out, as at 25, extends all the way
through the sole and the insole of the shoe. The
insert portion 26 on the heel 21 is correspondingly
proportioned. This insert 26 is of the same gen
eral shape as the insert I 5 shown in Fig. 1. How 50
ever, a different securing means is provided. As
here shown, a clip 28 having wings 29 extending
across over the margins 30 of the sole and insole
is used. This clip has an angularly depending
prong 3| extending from the back portion there 55

of. This prong is adapted to be projected down
into the insert 26 and its angular direction op
poses that of the bevel 32 at the forward end of
the insert. Over the upper portion of this clip
the shoe lining 33 is ?tted.
It will be seen that, in this type of design, the
clip 28, by means of the wings 29 engaging onto
the margins 30 of the insole and by means of the
prong 3|,‘will maintain the heel in place. The
prong 3| may be made fairly freely removable
from the insert and, if desired, the wings 29 may
be cemented down in order to prevent slippage.
It will be understood that this clip is readily
removable by any convenient tools, such as a
screw driver or knife or such similar instruments.
It likewise may be reinserted with little difficulty.
The modi?cation shown in Fig. 9 is similar to
that shown in Fig. 1 save that, in place of the
ball and depression detent means, a drive screw
20 40 is employed. This drive screw engages down
through the insole of the shoe into the insert of
the heel. It may be readily applied with a
hammer or the like and removed by means of a
screw driver. It is believed that its operation is

applied by the easy mechanism disclosed.
Having described the invention, what is claimed
is:
1. A shoe having a detachable heel receiving
cut-out therein, the part of the shoe bordering
a portion of the cut-out being beveled down
wardly toward the inside of the cut-out and the 15
remaining portion being substantially unbeveled,
a heel having an insert the shape of which is
complementary to said cut-out, ?exible means be
tween the insert and the heel receiving part of
the shoe at the cut-out to produce a binding ?t 20
between the same, and means for retaining the
insert in the cut-out, said means including a
ball. in the heel spring-urged to protrude there
from, and a depression in a wall of the cut-out
to receive the said ball in its protruding position. 25
2. A shoe and a detachable heel therefor, said
shoe having a cut-out therein, one wall portion
In each of the described types of heels, it will
be understood that the insert with its ‘beveled
front edge and its vertical side walls provides the
de?ning said cut-out being bevelled, said heel
having a projection, the shape of which is comple
mentary to the shape of the cut-out and engage 30
able therein, said bevelled surfaces providing a
principal means for holding the heel in place.
30 When the wearer of a shoe steps down on a heel,
the direction of force applied will tend to set the
heel more ?rmly at this beveled portion. It has
been determined that the detent means is little
more than merely a sustaining device to hold the
partial retaining means for the heel, a recess in
the projection opening in a wall remote from the
bevelled portion, a ball in said recess, a spring
urging said ball into protruding position relative 35

to the said recessed wall, and a depression in the
sole adapted to lie opposite the recess opening
when the projection is ?tted into the cut-out,
whereby the heel can be instantaneously opera
tively positioned in the cut-out or removed there
subjected to much force in ordinary use.
With a heel of this type, the insert may be
made of rubber or it may be made of an in?exible
material. In case it is made of rubber, it will
be understood that the binder, such as at 2! in
Fig. 3, may be eliminated. Indeed, this binder is
not essential to the successful operation of the

It will be understood further that, in addition
to its function of providing a removable and Ll
readily replaceable heel for shoes, this invention
provides a simpli?cation in the manufacture of
shoes, since the heel may be made separately and
