  SPORTS SHOE WITH BASE FABRIC UPPER

ARAMID FIBERS

  The subject of the present invention is a sports shoe, in particular a football shoe, comprising a upper and a sole.

  possibly fitted with studs.

  Sports shoes, including football shoes, made from a wide variety of materials are known. Usually these shoes are made of skin or plastic. Shoes are also known, the upper of which is made of plastic material covered, at the places where the mechanical stress is strongest such as at the forefoot of the shoe, by pieces of composite material such as carbon fibers, fibers aramid or the like. These shoes usually have a relatively rigid upper which gives them a significant weight and which, in the case of football boots, does not allow

  not an optimal control of the ball.

  The object of the present invention is to provide a sports shoe perfected by

  compared to the aforementioned shoes.

  More specifically, the present invention aims to provide a light sports shoe

  and having remarkable resistance to wear.

  The object of the invention is also to obtain a shoe, in particular a football shoe, which makes it possible to reduce the efforts provided by the athlete who wears it and which allows control.

optimal of the balloon.

  2- This object as well as others which will appear obvious to the skilled person are achieved thanks to

  a shoe according to the appended claims.

  For a better understanding of the present invention, reference will be made to the attached drawing for purely indicative purposes in which: FIG. 1 is a perspective view of a shoe according to the invention; and Figure 2 is a sectional view along the

line 2-2 of figure 1.

  If one refers to the aforementioned figures, the reference 1 generally designates a football boot according to the invention comprising a upper 2 and a sole 3 on which is disposed a first interior 3A. Sole 3 is provided with

cleats 4.

  The rod 2 according to the invention is, at least for the most part, made of fabric based on aramid fibers (known under the trade designation of kevlar) of very reduced thickness (between 0.3 and 0.7 mm

  for example) and very resistant to wear.

  More specifically, said fabric rod based on aramid fibers has an external surface 5 of notable roughness, with diffuse reliefs (possibly accentuated by lines of depression 6) distributed uniformly. Said fabric is associated, on its opposite face 7 (that is to say facing inward 8 of the shoe) with a plastic film 9 used to waterproof the upper -3- and to prevent moisture outside and / or water in the air or on the ground does not enter the shoe. As an alternative, or in addition to said film 9, the surface 5 can be impregnated with conventional water-repellent varnishes. Impermeability is an important property: in fact, the aramid fiber fabric absorbs (without retaining them) water and moisture in a considerable way and it is therefore advisable to prevent any water infiltration or moisture inside the shoe. The impregnation of the fabric and / or its waterproofing allows the shoes not to become heavy with use and to present no

  problem for the athlete wearing them.

  Finally, film 9 is associated with conventional padding 10, placed inside the shoe.

  on the wall 8a of its internal cavity.

  The ends 12 of the usual closure edges 13 and 14 of the shoe are preferably covered or directly made of a material at least partially semi-rigid, such as the skin, the

  leather, plastic or the like. This semi

  rigidity allows to place, at the level of said

  ends, classic laces.

  This type of material is also preferably used to make the rear part 15 of the shoe which must, as everyone knows, be rigid and support the foot, as well as each insert or

ornament 18 present on the stem.

  The sole 3 can be produced in a

  any material, for example plastic.

  4- However, said sole can also be made from aramid fibers or another composite material; if necessary, the rear part 15 of the shoe can be made as an extension of the sole upwards. Similarly, other reinforcements in composite material can be made at the front or on the sides of the upper as extensions of the sole 3 upwards. This solution facilitates the connection of the upper to the sole and to the aforementioned reinforcements (which is obtained by a usual bonding operation) compared to the case where the shoe comprises a plastic sole and reinforcements in

  plastic, skin, leather or the like.

  A shoe designed according to the invention is light, resists abrasion and, thanks to the roughness of its surface 5 (intrinsic and resulting from the use of aramid fiber fabric), allows control

optimal of the balloon.

  A soccer shoe has been described. It is obvious, however, that any other shoe

  having the features of the claims

  The following are within the scope of the present invention. -5-
