PROVISIONAL SPECIFICATION.
Improvements in the Soles of Boots and Shoes.
We, CHARLES LEWIS and EDWARD LEWIS, both of Chalk Lane, Northampton,
in the County of Northampton, Shoe Manufacturers, do hereby declare the nature
of this invention to be as follows:-
Our invention relates to the inner, middle and outer soles of boots or shoes and
its object is to render them more pliable than those in general use without in any
way diminishing their wearing qualities but imparting to them great lightness
strength and flexibility.
We provide the usual inner sole, the middle sole or welt, and the outer sole and
corrugate or groove them preferably transversely to the length of the boot or shoc.
These corrugations or grooves are cut out of the undersurface of the inner sole
throughout the whole or nearly the whole length thereof.
The middle sole or welt we groove on the upper surface throughout its length
and we groove the outer sole likewise on its upper or inner surface but only at the
waist portion.
-
We find that this method of corrugating or grooving the soles is far more effective
than previous methods and their flexibility makes them more comfortable to the
foot and affords greater comfort and case to the wearer of the boot or shoe and it
also lessens the strain on any particular part thus adding to their durability.
Dated this 7th day of November 1891.

this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
Our invention relates to the inner middle and outer soles of boots and shoes and
its object is to render such soles lighter and more pliable without interfering with
the durability or wearing qualities of boots or shoes furnished with them and in
carrying such invention into practice we provide the usual inner sole middle sole
(or welt) and the outer sole and these soles we corrugate in the following manner.
We corrugate or groove the inner sole preferably transversely (or diagonally)
throughout the whole of its length but on its under surface (Figure 1). The
middle sole (or welt) we corrugate in a similar manner but on its upper surface
(Figure 2) and the outer sole we also corrugate in like manner on its upper surface
(or inside) but in the waist portion only (Figure 3).
The soles are attached in any well known manner and the boot or shoe when
completed will be found more comfortable flexible and durable than boots or shoes
provided with soles corrugated in other manner, no particular part being unduly
strained.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
In the manufacture of boots and shoes corrugating or grooving the underside of

page_text: the inner sole and the upper surfaces or insides of the middle sole (or welt) and the
outer sole the latter in the waist only substantially as hereinbefore described.
