In order to achieve the above object, the shoe inserts such as counters and toe caps related to the present invention are made by crushing open-cell polyurethane foam to form a flat plate of a predetermined thickness.
It has a foam sheet part and a polyurethane reinforcing layer that is laminated and solidified on the inner circumferential wall of open cells in this sheet part without losing the cells.
本考案は先ず、次の工程を行つて芯材イを製造

層５とをもつ芯材イを得る。 That is, first, a polyurethane polymer 2 diluted to 2-3% with thinner is applied to the surface of an open-cell polyurethane foam 1 with a thickness of 10 to 15 mm, and then the polyurethane foam 1 is coated with a thickness of about 1.5 mm. While heating the foam to a thickness of At the same time, the volatile gas of the thinner escapes to the outside through the open cells 3.
Even after the above-mentioned adhesion, volatile gases continue to escape and the polymer 2 is solidified, and after this solidification, the crushing is released. In this way, a core material A having the sheet portion 4 which remains compressed and the reinforcing layer 5 provided on the inner circumferential wall of the open cells is obtained.

を薄くして当該カウンター７を完成する。 Next, a counter 7 is constructed by pasting the nonwoven fabric 6 on one side of the core material A, and the outer peripheral edge 8 of the core material A in the counter 7 is skimmed to form the same part 8.
The corresponding counter 7 is completed by thinning it.
本考案はその実施に際して次のことが可能であ

Γ 先芯で実施する。Γ Perform with the toecap.
Γ 不織布６の代りに布地、厚紙等当て材を使
う。Γ Instead of the non-woven fabric 6, use a backing material such as cloth or cardboard.
Γ芯材イの両面に不織布等当て材を貼り合せる。Paste non-woven fabric or other backing material on both sides of the Γ core material A.
Γ 芯材イに不織布等当て材を貼り合せない。Γ Do not attach backing material such as non-woven fabric to core material A.
Γ スキ加工を施さないで使用する。Γ Use without processing.
