Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The characteristics and advantages of the new sole having two portions made separately and subsequently assembled, according to the present invention, will become more clear from the description of a preferred, but not limiting, embodiment and from the enclosed tables of drawings, where:

[0015] FIG. 1 shows a side view and more precisely a view of the external part of a footwear with a lacing system having a single nylon cable and a rotor, wherein the two separate and assembled portions of the sole are highlighted and wherein said sole includes, in its upper portion, one of the two lateral plastic elements suitable for passing and guiding the nylon cable, according to the present invention;

[0016] FIG. 2 shows a top plan view of the lower part of the first portion of the sole, wherein lowered seatswhere the two lateral plastic elements are fixed and/or gluedare obtained, so as to allow passing and guiding the nylon cable; moreover, a central lowered seat is provided for passing and guiding the nylon cable, according to the present invention;

[0017] FIG. 3 shows a side view of a footwear and more precisely a view of the inner part of a footwear having a lacing system with a single nylon cable and a rotor, wherein the two separate and assembled portions of the sole are highlighted and wherein the sole also includes, in its upper portion, one of the two lateral plastic elements suitable for passing and guiding the nylon cable, according to the present invention.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] With reference to the attached figures, the sole (4), which is the object of the present invention, comprises two separate portions (4A, 4D) which are assembled at a later time; said sole (4) allows for obtaining different types of footwear (1) depending on the design of the tread provided on the lower part of a second portion (4D) of the sole (4); said footwear (1) is equipped with a lacing system which includes a single nylon cable (10) starting from a point underneath the closing flap (2) placed on the upper (1A, 1B) of the footwear (1) and passing over the instep and the inner part of the footwear (1), so as to enter the first portion (4A) of the sole (4), thanks to the presence of two guide elements (5), made of rigid plastic; the nylon cable (10) is also connected to the end part of the flap (2) and to the rotor (11), which is provided for tensioning the cable (10).

[0019] The first portion (4A) of the sole (4), also known as midsole, is made of plastic polymers, also recycled or recyclable, such as for example TPU or rubber or other non-rigid polymers. Said first portion (4A) of the sole (4) has a lower part (4B) on which lowered seats (4C) are made; said seats (4C) are configured to house two lateral elements (5); moreover, said lateral elements (5) are made of rigid plastic polymers and are configured for passing and guiding the nylon cable (10), which also passes centrally inside the lowered seats (4C); advantageously, the nylon cable (10) passing centrally inside the lowered seats (4C) is contained in a plastic tube which is inserted in one of said lowered seats (4C) and which is able to connect to each other said guide elements (5).

[0020] The second portion (4D) of the sole (4) is made of plastic polymers, also recycled or recyclable, such as for example TPU or rubber or other plastic polymers, which are consistent with the type of tread suitable for the type of footwear (1) to which is destined. Advantageously, said second portion (4D) internally has plastic or metal elements, in order to couple technical elements, such as for example studs or nails for golf.

[0021] The invention thus conceived and illustrated herein is susceptible of numerous modifications and variations, all falling within the scope of the inventive concept as defined in the attached claims.

[0022] Furthermore, all the details can be replaced by other technically equivalent elements.

[0023] Finally, the components used, as long as they are compatible with the specific use, as well as the dimensions, may be any according to the needs and the state of the art.

[0024] Where the features and techniques mentioned in any claim are followed by reference marks, such reference marks have been included for the sole purpose of increasing the intelligibility of the claims and, consequently, have no limiting effect on the interpretation of each element which is identified, by way of example, by them.
