> This invention relates to a novel device for women’s
boots and in particular to an insert which will increase
the useful life of the boot by protecting the inner portions
of the boot heel from damage orrapid wear. In partic
ular, the invention is directed to an insert which is urged
into the bottom portion of a woman’s boot heel and re
mains ?rm in that position.
1 It is still a further object of the invention to provide
means to prevent scu?ing or scarring of the spiked shoe
heel which is adapted to ?t within a boot heel construc
tion embodying the principles of the invention.
To the accomplishment of the foregoing and related
ends, said invention then, consists of the means herein
after fully described and particularly pointed out in the
claims; the following description setting forth in detail
The increased popularity of the so-called spiked heel‘ 15 one approved means of carrying out the invention, such
for women’s shoes has given rise to a considerable prob
lem as a result of the tendency of these higher, pointed
heels to pierce the heels of rubber or plastic boots worn
in connection with the higher-heeled shoes. These spike
\heels have lifts generally made of metal or some other 20
disclosed means, however, constituting but one of the
various ways in which the principles of the invention may
be used.
