4 Claims. (Cl. Bti-11)
This invention relates generally to shoes, and is par
ticularly concerned with shoes of the moccasin type.
In Older, and more conventional forms of moccasin
A primary object of the present invention is to satisfy
the aforesaid need, and provide a moccasin incorporat
ing components which can be machine sewn into fixed
relation with one another, but in such a manner as to
permit adequate shaping and adjustment of the compo
nents so that they can be brought close and snug to the
last ‘by means other than shrinkage.
More specifically,
it is an object of the present invention to provide in a
moccasin, an upper and sole portion comprising a blank
