METHOD OF MAKING ARCH-CORRECTIVE
SHOES
William M. Scholl, Chicago, Ill.
Original application January 10, 1936, Serial No.
58,457. Divided and this application October
2, 1936, Serial No. 103,636
1 Claim. (Cl. 12-'—142)
My invention relates to the manufacture of
shoes for foot-corrective purposes, and has for
its general objects to provide an e?cient and ad
vantageous method of making shoes especially
suitable for use in the relief of weak or fallen
arches.
This application is a division of my application
Serial No. 58,457 ?led January 10, 1936, which
application is directed to my new arch corrective
10
shoe.
'
Sufferers with painful arch-conditions com
monly wear what I may term “stock” arch-sup
ports in “stock” shoes, in seeking relief, and even
where only one foot is so effected it is common
the level for which the contouring of the “stock”
shoe is intended, with resultant disadvantages.
Even when “stock” shoes and arch-supports
are simultaneously bought, difficulties in ?tting
such shoes‘, with the appliances in place, not in
frequently result in conditions that militate seri
ously against the users comfort; against the
sightly appearance of the footwear, and even
against best functioning of the appliances to
give the desired foot-relief; and more speci?c
objects of my invention are to provide an ad
vantageous method of making improved shoes
that, in their normal condition for sale makes
them ?ttable exactly as'a corresponding size of
practice to wear such appliances in both shoes,
“stock” shoes would be, regardless of whether
to avoid the uneven effect or “limp” in walking
or not “stock” arch-supports are to be worn
that annoyingly results from wearing only one.
By my method improved shoes are produced that
therein; that gives them advantage in normally
affording a certain amount of arch-supporting
_
accommodate the wearing of a single arch-sup
20 port with little or no such uneven effect.
By “stock” shoes, as herein referred to, I al
lude to ready-made leather ones, internally con
toured for good fit upon a normal foot of the
size for which the shoe’s length and width are
25 indicated by conventional standards; and what
I term “stock” arch-supports are suitably stif
fened ortpadded appliances (of which various
speci?c constructions are commercially avail
able) to be loosely inserted in the user’s shoes and
30 to be positioned therein, in use, by coaction with
the shoe and the foot; such an appliance being
shaped in plan outline to underlie the foot’s width
from a line just back of the ball of the foot to
the rear of the heel’s under-surface, and the waist
' of the appliance having its inner side widened
and arched upward, conformably with the curva
tures of the foot’s longitudinal arch.
Such appliances commonly run in sizes marked
with the standard lengths and widths of corre
4 O sponding shoe sizes; but while such “stock” arch
supports are commonly thinned at the forward
edge to meet the shoe’s insole as smoothly as pos
sible, and while the lacing or buttoning arrange
ment of the shoe’s upper will accommodate con
siderable variation in the arch-depth of the ap
pliance at its waist without discomfort or mak
ing the shoe unsightly, the heel portion of the
appliance, upon which its proper positioning in
the shoe and its cooperative relation to the foot
quite largely depend, is customarily of substan
tial thickness for requisite stiffness and durability
(a thickness of about .125 of an inch being a
reasonable commercial average), so that the
wearer's heel is lifted in the shoe materially above
effect which tends to prevent occurrence of arch
troubles; and‘ that permits of the substitution,
at or after the time the shoes are purchased,
of a “stock” arch support for the detachable
“dummy” arch-supportive structure of either or
both of the normal shoes, with minimal discom
fort, shoe distortion, or other drawbacks.
Thus, the improved shoes to be made have their
foundation-structures-i. e., the permanently
united sole, heel, and upper—normally supple
mented by detachable “dummy” arch-supports or
lifts, the upper surface of which forms part of 30
the normal interior surface of the shoe that gives
the lasted depth and internal contouring of a
standard size of “stock” shoe; so that, when said
dummy is removed, the foundation of the shoe
affords an internal pocket or depression, through- ’
out its heel and shank portions, wherein a “stock"
arch-support may be inserted with but little, if
any, undesirable effect on the ?t, the appearance,
or the comfort of the foot-wear.
With respect to the manufacture of such shoes, 4.0
some of my more speci?c objects are to provide
for the efficient production of such shoes on the
same lasts that are used in the making of corre
sponding sizes and styles of stock shoes; to in
sure that the interior contouring of these special
shoes, with the dummy arch-support in place,
will exactly correspond with “stock” shoes of like
last-sizes, and to insure that‘ any slight variation
in the thickness of individual dummy arch-sup- 50
ports used in making up a quantity of the shoes,
will not affect the internal contouring of the
?nished foot-wear.
Further advantages of my invention will here
inafter become apparent from the following 619- 55

scription, taken in conjunction with the accom
panying drawing wherein I have shown one de
sirable embodiment of and practice of my inven
tion, including various details from which vari
ation may be made within the scope of the ap
pended claim, but which I have found in prac
tice to give desirable results.
arch-support which is to constitute a part of the
?nished shoe may be used, or a substantial coun
' terpart of it; the appropriate “lasting-dummy”
being tacked to the last as at 29 and the shoe
being lasted over it.
In the drawing,
Figure 1 is a» perspective view showing, in con
ventionalized fashion, a suitable shoe to be made
by my method, cut away in longitudinal section
and having a “dummy” arch-support detach
ably secured in appropriate position therein; the
visible part of said dummy having fragments
15 broken away;
Fig. 2 shows in perspective a shoe-last suitable
for use in making the construction shown in Fig.
1 associated, as in a manufacturing step, with
a broken-away part of the “dummy”; and
Fig. 3 is a perspective view of a suitable “dum
20
my”, detached.
In the drawing, Hl indicates in general the
permanent body or foundation of the shoe to
be made, conventionalized in the showing of its
25 sole ll, shank l2, heel l3, and upper l4.
[,8 indicates in general an arch-support
“dummy”, or removable lift, that normally is
secured in place in the shoe body, and the top
surfaces of which form part‘of the normal in
30 terior contouring of the merchantable shoe, giv
ing it interiorly a “stock” shoe shape, substan
tially duplicating that of regular “stock" shoes
of the same make and size.
This dummy, [8, simulates a stock arch-sup
35 port in plan outline, and the depth or thickness
of its heel portion l9 and the tapered thinning
of its forward edge 26 are in keeping with aver
age practice in the manufacture of well-known
stock arch-supports; the waist 2| of the dummy
40 being preferably somewhat thinner than is cus
tomary in “stock” arch-supports for the longi
tudinal arch of the foot and being preferably
Wholly of leather.
A thin body of adhesive, 22,
adjacent the forward edge of the dummy, may
45 be used to secure it normally to the insole or
sole-lining of the shoe, for easy~enough removal
on occasion.
The desirable construction of dummy I8 here
shown comprises a preformed leather top piece
24, suitably arched and skived along the inner
50 side of its waist-portion 2|, and with its heel
portion underlain by a reenforcing layer 25,
In practice, the amount of surplus upper
material that ordinarily is provided before the
excess is trimmed away in the manufacturing
operation, is ample to accommodate the deep
ening of the permanent body of the shoe suffi 10
ciently to provide a dummy-receptive space or
pocket A—A1 throughout the heel and shank
areas of the shoe, so that, with the dummy
in place, the full foot-reception depth A—B, and
the last-counters, of the affected area are pre
“dummy” arch-support that is intended to be
incorporated in the particular shoe being lasted
is utilized as the depth-increasing addendum to
the last, its heel-plate 25 serves as a nailing 25
plate in the manufacture of the shoe, to upset
the ends of the heel-nails; and that such use
of the identical dummy insures that the in
ternal contours of the completed shoe will con
form with great precision to that of a stock 30
shoe made over the naked last, so that no change
from a favored last and size is needed, on a
customer's first requirement for arch supports.
In practice, the wearing of a “stock” arch
support in the pocket A-A1 that is exposed upon 35
removal of the "dummy” arch-support, not only
goes very far to avoid discomfort to the wearer
and malformation of the shoe, whether worn in
both shoes or only one; but also it reacts to fur
ther the effectiveness of the corrective appliance
itself, particularly by minimizing any tendency
of the loosely-inserted stock appliance to work
away from proper position in the shoe, and by
avoiding that slight increase in pitch of the shank
of the wearer's foot with respect to the ground 45
which follows from the use of stock arch-sup
ports in stock shoes.
I claim:
A method of making arch corrective shoes, ini
tially of “stock” contour internally to fit a nor
mal foot and adapted to permit the wearing, in
either one of a pair, of a stock arch support
which here is shown as a short metal heel-plate
without materially lifting the affected portion
secured to the top piece by rivets 26. Desirably,
55 the forward end of this plate has its inner corner
slightly arched upwardly, as at 21, this “corner
hump” tending to prevent forward slipping of
the foot in the shoe; to check any tendency of
of the user's foot with respect to the shoe heel
and so producing “limp effect”, comprising the
the wearer to rock to the inner side of the foot
60 in walking; and to prevent displacement of the
scaphoid-just back of which the hump exerts
its slight pressure.
steps of so securing to a stock last a lasting
dummy of leather and metal, contoured con
formably with a “stock” arch support, as to po
sition its skived front edge on a transverse line
just back of the last’s ball, its broadened waist 60
to extend high up the inner side of the last's
arch and its metal-bottomed heel-portion to
For purposes having to do with a desirable
cover the heel-bottom of the last and locate the
procedure in making the shoes, the plate 25 is
65 provided with a central tacking-opening 28.
In manufacture of my improved shoes, it is
metal to serve both as a nailing-plate and a
desirable to use the same lasts 30 on which stock
shoes are made; the last shown in Fig. 2 being
of conventional style having the usual heel
70 plate 3| to upset the points of. the nails for
the shoe-heel l3, such plate having a tacking
aperture with which the opening 28 registers.
To give the added depth to the shoe being
made, necessary to accommodate the proper
75 dummy arch-support, that particular dummy
15
served; and a reduction of height of the shoe
heel I3 is desirably made, to preserve a total
height B—C at the rear of the shoe correspond
ing with the height of stock-shoe for which the
20
naked last is designed.
It will be noted that where the identical

the lasting dummy in contour and structure, with
its forward edge portion adhesively connected
with the shoe sole just back of the ball.
