1 Claim. (Cl. 36--14)
The present invention relates to improvements in the
production of articles of footwear, and more particularly
to improvements in shoes of the type having a vulcanized
article of footwear embodying my invention;
FIG. 2 is a transverse section through the article of
footwear as seen in the direction of arrows from the line
B-B of FIG. l; and
FIG. 3 is a transverse section taken along the line
A--A of FIG. l, as seen in the direction of arrows.
Referring now in greater detail to the illustrated ern
bodiment, there is shown an article of footwear in the
form of a shoe comprising an upper which includes an
outer layer or vamp l and an inner layer or lining 2,

downwardly beneath and connected to the edge portion
For example, a shoe of this type is disclosed in

shoe with a vulcanized sole which is constructed and
assembled in such a way that the sole is safely secured
and which defines with the latter a toe receiving space is
