Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the embodiments of the present invention, and should not be construed as limiting the utility model.

In the description of the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present invention, "a plurality" means two or more unless specifically limited otherwise.

In one embodiment of the present invention, as shown in fig. 1 to 6, a double-layer shoe shield is provided, which includes a hard shoe shield body 1 and a soft plastic layer 2. The rigid shield body 1 is shaped to match the toe cap and has an outer surface 11 and a first inner surface 12. The hard shoe shield body 1 is made of hard plastics, and the Shore hardness of the hard plastics is more than or equal to 35D. The soft plastic layer 2 is arranged on the first inner surface 12 and is made of soft plastic, and the shore hardness of the soft plastic is less than or equal to 60A.

The double-layer shoe shield adopts a design of soft inside and hard outside, the hard shoe shield body 1 is arranged on the outer layer, and the hard shoe shield body 1 has high structural strength and provides a strong supporting effect; the inlayer then is soft plastic layer 2, and soft plastic layer 2's material is soft plastic, and when dressing, soft plastic layer 2 laminating instep plays the cushioning effect, prevents to gouge and prevent frostbite. This double-deck shoes shield has the comfortable advantage of wearing.

In an embodiment of the present invention, the shore hardness of the rigid plastic of the double-layer shoe shield is more preferably 50-80D; the shore hardness of the soft plastic is more preferably 5-40A. The design is more comfortable to wear.

In another embodiment of the present invention, as shown in fig. 2 to 4, said soft plastic layer 2 of the double-layer shoe shield matches the shape of said first inner surface 12, said soft plastic layer 2 covering said first inner surface 12. By adopting the above full-covering design, the protection effect of the soft plastic layer 2 can be further improved.

In another embodiment of the present invention, the double-layer shoe shield further comprises a plurality of ventilation holes 3, wherein the ventilation holes 3 penetrate through the hard shoe shield body 1 and the soft plastic layer 2. The air holes 3 play the roles of ventilation and heat dissipation, and are more comfortable to wear. The plurality of air holes 3 are arranged on the hard shoe shield body 1 in a plurality of rows; the number of the air holes 3 is reduced from the middle to the two sides. The middle part of the human toe is longer, and the toes on two sides are shorter, so the design is more in line with the characteristics of the human structure.

In another embodiment of the present invention, as shown in fig. 1, the outer surface 11 of the double-layer shoe shield is provided with a plurality of evenly distributed anti-slip protrusions 13. The anti-slip bumps 13 play a role in increasing friction and preventing slip.
