This invention relates to shoes and the manu
facture thereof and is particularly concerned
with so-called slip-lasted platform shoes and
methods of making such shoes.
An important object of the invention is to pro
vide an improvedrnethod of making slip-lasted
platform shoes the practice of which is simple,
convenient and economical, and which will pro

like. The parts are secured together with their
marginal portions in superimposed relation by
stitches, 'as explained above, with the upper and
insole positioned wrong side out at opposite sides
vide platform shoes whose strength, shape and
wearing qualities are equal, if not superior, to
shoes of that type produced by other methods.
To this end the invention provides, in accord
ance with one of itsaspects, an improved method
of makingplatform shoes which consists ‘in se
' curing an upper, a relatively wide edge covering 15

of the welt. The upper is turned right side out
thereby locating the stitches inside the shoe and
causing the welt to? extend outwardly from be
tween the upper and insole member. A platform
sole is laid on the shoe bottom and secured
thereto, the platform sole in this construction
preferably being relatively thin or of the type
commonly known as a “wafer” platform vsole.
The Welt is wrapped around the'edge portion of
the wafer platform sole and inwardly beneath
its bottom surface and is secured to said surface
.by cement or other means, after which an out
sole is permanently attached to the inwardly
extending portion of the welt, preferably by ce
ment. The outsole in this construction is ap
proximately as thick as the wafer platform sole.

another aspect, an improved method of making

Figs. 12 to ‘15, inclusive, illustrate still another =
form of platform shoe in which an insole 59 of -
substantially normal thickness and preferably
composed of relatively ?rm material, such as
leather, fiber or the like, is mounted on the last
38 before the latter is inserted into the upper
to slip-last the shoe. As shown in Fig. 12, the
upperiil, covering strip 32, and flexible insole
34 are secured together while off a last by stitches
35; as described above, with the upper and insole
positioned wrong side out at opposite sides of
the covering strip. The upper is turned right side
out and the last, with the normal insole 58
mounted thereon, is inserted into the upper to
slip-last the shoe. The outer or exposed sur
face of the insole 56 has an adhesive thereon,
the adhesive preferably being of the slow-drying

close to the edges of the parts, these edges, as
described above, preferably being substantially

insole are positioned inside out with their outer
surfaces engaging the opposite sides of the welt.
The seam 60 is preferably rolled or rubbed down
to reduce any bulge or bunch formed where the
three layers of material are stitched together
and the upper is then turned right side out and
a last 62 inserted into the upper to slip-last the
shoe, as shown in Fig. 17. A platform sole 64 of
relatively yielding material is attached to the

sole. The welt or strip 58 is wrapped downward
plied to the shoe bottom, thereby causing the
insole 5D to remain permanently in the shoe.
The normal insole 58 is usually mounted on the

17 to 21, inclusive, could, of course, be provided
with insoles of substantially normal thickness
and composed of relatively ?rm material, such as
leather, ?ber or the like, merely by mounting
such insole on the last 62 before the latter is
