METATARSAL PAD
Abstract
An external metatarsal pad is provided for a woman's high heel
shoe. The pad comprises a flexible resilient material having a
substantially uniform maximum thickness in the rear portion of the
pad. The pad is gradually and uniformly tapered at its forwardmost
end from the area of maximum thickness. The pad is secured to the
outer lower surface of the sole of the shoe. The tapered portion
acts to inhibit the viewability of the pad while the area of
maximum thickness acts to cushion the metatarsal area of the foot
of the wearer of the shoe.

Claims
What is claimed as the invention is:
1. In combination a high heel shoe and a metatarsal pad for said
shoe, said pad comprising a flexible resilient material, said pad
being secured to the tread face of the shoe tread sole and
extending from the toe area to the break line of the shoe, said pad
having tapered side and front marginal portions, gradually
thickening towards the heel to maximum thickness on the rear
central portion thereof, said tapered portion acting to inhibit the
viewability of said pad while said area of maximum thickness acts
to cushion the metatarsal area of the foot of a wearer of said
shoe.
2. The combination of claim 1 wherein said pad is adhesively
secured to the sole of said shoe.
3. The combination of claim 1 wherein the periphery of said pad is
spaced inwardly of the periphery of said sole to further inhibit
visibility of said pad.
Description
Women's high heel shoes act to provide maximum pressure on the
metatarsal area of the foot. That is, the front portion of the foot
must support more of the weight of the body as the elevation of the
heels increases. The elevation of the heel with respect to the
forwardmost portion of the foot, thus, acts to focus the weight of
the metatarsal and phalanges causing the metatarsophalangeal joint
to receive maximum pressure. Unfortunately, in women's shoes, the
styling thereof dictates that minimum thickness of the sole be
provided under the metatarsophalangeal joint. Thus, where the
pressure is greatest, the least cushioning is provided in a woman's
high heel shoe. Moreover, the manner in which women's shoes are
constructed requires a close or snug fit of the shoe at the
metatarsal region of the foot so that the shoe will not fall off.
Accordingly, there is little or no room for the placement of a
cushioning pad within the shoe.
It is, therefore, an object of the invention to overcome the
aforementioned problems in women's high heel shoes.
Another object of the invention is to provide a new and improved
metatarsal pad for women's high heel shoes.
Yet another object of the invention is to provide a metatarsal pad
which is adhesively secured to the outer lower sole of a woman's
shoe.
Yet another object of the invention is to provide a new and
improved metatarsal pad for women's high heel shoes which is
secured to the outer lower surface of the woman's shoe and which is
substantially invisible yet provides maximum cushioning of the
metatarsophalangeal joint of the foot.
These and other objects of the invention are achieved by providing
an external metatarsal pad for a woman's high heel shoe. The pad
comprises a flexible resilient material having a substantially
uniform maximum thickness in the rear portion of the pad. The pad
is gradually and uniformly tapered to its forwardmost end from the
area of maximum thickness. The pad is secured to the outer lower
surface of the sole of the shoe. The tapered portion acts to
inhibit the viewability of the pad while the area of maximum
thickness acts to cushion the metatarsal area of the foot of a
wearer of the shoe.
Other objects and many of the attendant advantages of this
invention will be readily appreciated as the same becomes better
understood by reference to the following detailed description when
considered in connection with the accompanying drawings
wherein:
FIG. 1 is a perspective view showing the lowermost portion of a
woman's high heel shoe embodying the invention;
FIG. 2 is a perspective view of a metatarsal pad embodying the
invention per se; and
FIG. 3 is a sectional view taken along the line 3--3 in FIG. 2.
Referring now in greater detail to the various figures of the
drawing wherein like reference numerals refer to like parts, a
woman's high heel shoe embodying the invention is shown generally
at 20 in FIG. 1.
Shoe 20 basically includes an elevated or high heel 22 and a sole
24. Secured to the sole 24 is a pad 26. Shoe 20 is of conventional
construction and, of course, includes shoes having soles made of
leather or thermoplastic substitutions therefor.
Pad 26 is basically comprised of a flexible resilient material
capable of providing a cushioning effect for the metatarsal area of
the foot.
As best seen in FIG. 3, the pad 26 includes a rear portion 28 which
is the thickest portion of the pad and which is uniformly thick.
Portion 28 extends approximately one-third of the length of the
metatarsal pad from the rear of the pad towards the forwardmost end
30. Portion 32 is substantially uniformly tapered from area 28 to
the forwardmost end 30.
As best seen in FIGS. 1 and 3, the outer periphery 34 which extends
around the rear portion 28 of the metatarsal pad is rounded. Prior
to securement of the pad 26 on the lower outer surface of a sole of
a woman's shoe, the uppermost surface 36 of the pad is
substantially flat. The flexible nature of the material comprising
the metatarsal pad 26 enables the pad to conform to the shape of
the sole 24 of the shoe 20.
The metatarsal pad 26 is preferably secured to the sole 24 by an
adhesive. A preferred adhesive is Duall No. 88 All Purpose Cement
which is applied between the top surface 36 of the pad 26 and the
sole 24.
The rearmost edge 34 of pad 26 is positioned below the metatarsal
heads of the foot and the forwardmost portion of the pad extends
towards the toes of the foot. The portion 28 of the pad is
positioned directly below the metatarsophalangeal joint to provide
maximim cushioning.
The external metatarsal pad 26 is also so dimensioned that the
periphery of the pad is spaced inwardly from the periphery of the
sole of the shoe as seen in FIG. 1 to further prevent visibility of
the pad.
It can, therefore, be seen that a new and improved metatarsal pad
has been provided. The maximum thickness area of the metatarsal pad
provides maximum cushioning to the metatarsal area of the foot
while the tapered portion of the pad makes the pad substantially
invisible since viewability thereof is inhibited. The pad is
quickly added to the shoe and does not alter in any manner the fit
of the shoe to the foot.
Moreover, since the external metatarsal pad elevates the forefoot
only, there is redistribution of the weight on the foot which
causes a reduced load on the metatarsophalangeal joint as more of
the weight of the body is received by the heel. The stress on the
metatarsophalangeal joint is further relieved by the elevation of
the forefoot with respect to the heel thereby reducing the angle of
elevation of the metatarsal.
Without further elaboration, the foregoing will so fully illustrate
my invention that others may, by applying current or further
knowledge, readily adapt the same for use under various conditions
of service.
