In the following description, only the parts of the shoe are described.

The fiber composite product 1 of the present embodiment comprises: a resin portion 11 composed of an epoxy resin, two substrate layers 12 having the same area and covering the inside of the resin portion 11, and a plurality of areas smaller than the substrate layers 12, a thickening layer 13 covering the inside of the resin portion 11, and a first film skin layer 14 and a second film skin layer 15 adhered and fixed to the resin portion 11.

The resin portion 11 of the present embodiment has a first surface 111, a second surface 112 spaced apart from the first surface 111, a main structural region 113 adjacent to the first surface 111, and a main structural region 113 A thickened region 114 that embosses toward the second surface 112. The second surface 112 has at least one grain 115 opposite to the thickening region 114. In a preferred embodiment, the texture 115 is formed by a plurality of protruding regions forming a star shape, but the texture 15 may also be a concave structure or a different graphic or text.

In the present embodiment, the substrate layers 12 are fibers woven from fibers, which are the main structural regions 113 corresponding to the resin portion 11. Preferably, the substrate layers 12 are selected from structural strengths. Fiber, specifically for example: carbon fiber, fiberglass, or a combination of these. The thickening layer 13 is also a fabric woven from fibers. Preferably, the thickening layer 13 is selected from fibers having relatively low structural strength, such as polyester fibers and polyamines. Man-made fibers such as fibers (also known as nylon, Nylon in English), or a combination of these. The area of the thickened layer 13 is gradually reduced toward the second surface 112 of the resin portion 11 from the side adjacent to the base material layer 12.
