A method of manufacturing a shoe, comprising the steps of:
- providing a mold center piece and a mold shaped to form a shell body of the shoe;
- mounting a liner in contact with at least a portion of the outer surface of said mold center piece;
- coating at least a portion of the outer surface of said liner with a hot-melt bond material;
- placing the combination of said mold center piece, said liner and said hot-melt bond material into said mold such that a space is formed between said mold and the combination of said mold center piece, said liner and said hot-melt bond material;
- filling said space with a heated molten synthetic resin material such that heat from said heated molten synthetic resin material causes said hot-melt bond material to melt;
- and
- cooling said synthetic resin material and said hot-melt bond material such that said synthetic resin material forms said shell body, and said hot-melt bond material bonds to said shell body and said liner and acts to stiffen said shell body.
