PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Boots and Shoes.
I, ISIDOR MANSCHESTER, of 143, Bute Road, Cardiff, in the County of
Glamorgan, Waterproof Garment Manufacturer, do hereby declare the nature
of this invention to be as follows :-
This invention relates to improvements in that class of boots and shoes which are
or may be provided with outer soles of india-rubber or like elastic waterproof
material.
A great objection to such boots and shoes is that by their use the feet of
the wearers become heated and drawn, and my invention has for object to obviate
this defect.
In carrying out my improvements I manufacture the boots and shoes in a similar
manner to that hitherto adopted but I provide the india-rubber outer sole with a
number of perforations or openings, such perforations or openings being filled up by
pieces of leather or other suitable material which are directly connected to the
leather insole. In order also to provide a better ventilation of the sole I some-
times form the inner surface of the elastic outer sole with a number of grooves or
their equivalents so as to leave a space between the inner and the outer sole, through
which the air can circulate or pass.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Boots and Shoes.
1, ISIDOR MANSCHESTER, of 138, Richmond Road, Cardiff, in the County of
Glamorgan, Waterproof Garment Manufacturer, do hereby declare the nature of
this invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to improvements in that class of boots and shoes which are
or may be provided with outer soles of india-rubber or like elastic waterproof
material. A great objection to such boots and shoes is that by their use the feet
of the wearers become heated and drawn, and my invention has for its object to
obviate this defect.
In carrying out my improvements 1 manufacture the boots and shoes in a similar
manner to that hitherto adopted but I provide the non-conducting india-rubber
outer sole with a number of perforations or openings, such perforations or openings
being filled up by pieces of leather or other suitable conducting material which are
directly connected to the leather inner or middle sole. In order also to provide a
better ventilation of the sole 1 sometimes form the inner surface of the elastic outer
sole with a number of grooves or their equivalents so as to leave a space between
the inner and the outer sole, through which the air can circulate or pass.
In the accompanying drawing,
Figure 1 is a plan, and
Figure 2 is a longitudinal section of a boot or shoe-sole made according to my
invention.
a is the elastic waterproof outer sole having a number of perforations or openings
filled in by pieces of leather or other suitable conducting material directly
connected to the leather insole c.
d, d are the grooves which I sometimes form in the inner surface of the elastic

page_text: outer sole a such grooves serving for the circulation of air between the two
soles.
By my invention I obtain the advantage of a boot or shoe having a sole of
conducting material combined with the grip of one provided with a rubber sole.
Having now particularly described and ascertained the nature of my said inven-
tion, and, in what manner the same is to be performed, I declare that what I
claim is :-
1. In a boot or shoe having an elastic waterproof outer sole, providing the said
elastic outer sole with a number of perforations or openings filled up by pieces of
leather or other suitable conducting material directly connected to the leather
insole, substantially in the manner and for the purpose hereinbefore described and
illustrated in the accompanying drawing.
2. In a boot or shoe having an elastic waterproof outer sole, providing the inner
surface of the said elastic outer sole with a number of grooves or their equivalents,
substantially as and for the purpose herein before described and illustrated in the
accompanying drawing.
