Embodiment Construction

[0037] figure 1 is a schematic illustration of a variant of an embodiment of the protective element of the invention intended to be inserted into an article of footwear.

[0038] figure 1 To give an example of the general shape of this protective element with the housing 2, the housing 2 consists of a front part 2a; the front part 2a is specifically intended to receive the toes of a dancer, and this front part is extended into a rear part 2b.

[0039] In this example, the rear part 2b is in the shape of a tongue, which protrudes from the front part 2a.

[0040] figure 2 show figure 1 Cutaway view of the middle part of the protective element.

[0041] exist figure 2 It can be seen that the housing 2 is provided with an inner part 3 intended to contact the dancer's toes and an outer part 4 facing opposite.

[0042] In this variant, the rear part 2 b of the housing 2 is itself provided with a part inner part 3 and part outer part 4 .

[0043] Alternatively, however, the ...

Abstract

The invention relates to a protective element for footwear, to footwear having the protective element built therein, and to a method for manufacturing said protective element, with use in the field of dance shoes. The protective element is to be inserted into the front portion of the footwear and includes a shell 2 for enclosing the toes of the user. Said shell forms a one-piece assembly including an internal portion 3, for making contact with the toes of the user and formed of a resilient material having a first hardness, and an outer portion 4, opposite the inner portion and formed of a rigid material having a second hardness that is greater than the first hardness. The outer portion is formed by injecting the rigid material, having a second hardness, into a first mold. The inner portion is formed by injecting the resilient material, having a first hardness less than the second hardness, into a second overmolding mold wherein the outer portion 1 is positioned.

Description

technical field [0001] The subject of the invention relates to a protective element for footwear, an article of footwear provided with said protective element and a method for manufacturing said protective element. [0002] The invention finds particular application in the field of dancing shoes; more commonly known as "pointe shoes", which make the dancer perform a lifting motion on the toes, and which therefore require strengthening of the toe. Background technique [0003] Traditionally used dancing shoes consist of a usually leather sole to which a flexible cover is fastened; this cover is called an upper and is made, for example, of satin. The shoe also includes a toe portion; the toe portion is composed of a hard shell or shell enclosing the toes; the toe portion extends under the foot by reinforcing the bone to reach the arch of the foot. [0004] The shoe must be both soft enough to allow the dancer to move on stage and tough enough to withstand the weight of the da...
