innersole board which can make the shoes/boots uncomfortable to
wear (see Huff ‘801 at column 1, lines 17 through 30, and Huff
‘491 at column 1, lines 20 through 33). To solve this problem,
Huff provides a rigid innersole board having detachable pieces at
the heel and forefoot impact areas which remain connected to the
board during the manufacturing process until shortly after the
application of the welt stitch. As described in each patent,
[a]s shown in FIG. 4, the welt stitch (17) is
applied through the rib (13), upper lining material
(27), upper (18), and PVC welt material (19), as is
normal procedure in any shoe or boot manufactured with
the Goodyear welt system. (Ibid.)
The pre-cut detachable pieces (11a, 11b) on the
innersole board (10) are now removed . . . . As best
shown in FIG. 2, the fresh openings (11a’, 11b’) expose
the high density EVA pad (15) that lies on top of the
innersole board (10). In the preferred embodiment, the
two cushioning pads (20a, 20b) are made of polyurethane
and cemented to the high density EVA pad (15) through
the new openings (11a’, 11b’). . . .
As can be seen in FIGS. 2 and 4, a filler (21) of
uniform thickness is die cut to fit inside the rib (13)
and cemented to the innersole board (10). . . .
A shank (23) is applied in its normal position, as
shown in FIGS. 2 and 4 . . . .
Turning now to FIG. 4, the midsole (24) is applied
and stitched to the welt material (19), locking in
place the cushioning pads (20a, 20b), shank (23), and
EVA rib filler (21), and compressing the cushioning
