Description

Description SHOES, IN PARTICULAR SPORTS SHOES, AND THE METHOD OF MANUFACTURED SUCH SHOES Technical Field The present invention relates to the technical field of footwear articles, in particular sports shoes, comprising two tubular textile elements used in the construction of the upper and possibly the sole of said footwear articles, and the manufacturing processes of such footwear articles. Previous technique Conventional footwear typically consists of an upper and a sole structure. The upper is secured to the sole structure and forms a cavity within the footwear to comfortably accommodate and secure the foot. The sole structure is attached to a lower section of the upper and positioned between the ground and the upper during operation. In athletic footwear, the sole structure may include an outsole and a midsole. The midsole often incorporates a polymer foam material that absorbs shock upon impact with the ground, thus mitigating the effects on the foot and leg during walking, running, or other ambulatory activities. The sole structure may also include a lining positioned near the bottom of the foot to enhance the footwear's comfort. The soles are traditionally attached to the uppers using a construction method called the Strobel method, during which the various sole components (insole, midsole, and outsole, in particular) are joined. The manufacturing processes for a classic shoe require dozens of steps and produce a significant amount of waste from material cutting. The aim is to simplify the manufacturing processes for footwear, particularly by reducing the number of steps and / or energy and material consumption. This issue also involves finding a manufacturing process that can be implemented as close as possible to the point of use of the footwear in order to reduce its carbon footprint, facilitate inventory management, and allow for customization of the footwear. One solution is to eliminate the sewing steps required to shape the initially flat stem into three dimensions. The stem is obtained by assembling one or a few pieces, rather than multiple pieces joined together by sewing. Footwear articles are known to include a tubular textile element comprising thermofused textile portions that form at least part of the upper. The aim is to improve these footwear articles to make them lightweight, flexible, and breathable, while... REPLACEMENT SHEET (RULE 26) offering satisfactory abrasion and tear resistance, and comfortably conforming to the shape of the foot. FR 3 098 690 Al describes the manufacture of a shoe from two superimposed tubular textile elements comprising yarns that are at least partly heat-fusible and which are thermofused during the thermoforming of the two tubular textile elements into an upper. FR 3 098 690 Al describes that it is possible to use different mesh patterns and different types of yarn (nature and / or color and / or transparency, cf.

[0126] ) but without specifying the type of thread, nor its arrangement in the shoe. Such footwear articles, despite a particular construction, must also offer varied designs respecting the technical criteria stated above, while limiting the aesthetic and / or functional component(s) necessary for their manufacture. It may therefore be desirable to create one or more viewing zones of a particular portion of the footwear from its exterior. One proposed method is to melt hot-melt yarns and form a transparent film-forming zone. However, this type of film-forming zone reduces the breathability and flexibility of the upper when the heat-fused monofilament yarns have a large diameter, or its abrasion / tear resistance when the heat-fused monofilament yarns have a small diameter. Furthermore, when the upper comprises an inner and an outer layer containing hot-melt yarns, these yarns adhere to the inner layer when heat-fused, further stiffening the treated area of ​​the upper. The aim is to create a viewing area that does not alter permeability, or at least limits the decrease in permeability, and maintains good flexibility in the region of the stem containing it, as well as good resistance to abrasion and tearing, particularly when a through opening is located in this viewing area.

Definitions In this text, the term "hot melt" or "hot melt first component" means any material or first component that is hot melted during the manufacture of the shoe according to the invention. In this text, the opening for the introduction of the foot in the shoe, sock (internal or external), or even a tubular textile element (internal or external) is understood to mean the natural opening for the introduction of the foot into the foot compartment of the shoe, sock, or tubular textile element, particularly situated between the midfoot and rearfoot regions, more specifically surrounding all or part of the ankle. In this text, "non-thermally fused" means any material / component that is not thermally melted during the manufacture of the shoe according to the invention. This material or component may be thermoplastic or not, but it must have a melting or softening temperature, or a degradation temperature, that is higher than the highest heating temperature used during the manufacture of the footwear according to the invention. In this text, transparent and / or translucent means any material, in particular any monofilament, through which it is possible to see one or more colors, and / or one or more patterns, possibly in relief. It is possible to vary the transparency of a monofilament wire until it is translucent by varying, for example, the mass percentage of titanium dioxide in the wire. In this text, the term "hot-fusible wire(s)" is understood to mean at least in part that the wire(s) in question is / are totally hot-fusible or each includes / include a portion of their structure which is hot-fusible. In one embodiment, the main internal textile portion comprises one or more transparent and / or translucent monofilament yarn(s), notably forming an internal viewing area. In one embodiment, the internal tubular textile element, in particular the internal textile part covering at least part of the foot, comprises: - one or more heat-melted textile portions, in particular one or more heat-fusible yarns, at least partially heat-melted during the manufacture of the shoe; and / or - one or more multifilament filaments and / or one or more spun fibers, in particular non-thermally fused, more particularly polyester and / or recycled fibers, for example PET (polyethylene terephthalate) or PBT (polybutylene terephthalate); and / or - one or more elastic threads, particularly made of elastane; and / or - one or more transparent and / or translucent monofilament yarn(s), in particular not heat-fused, arranged in the main, respectively additional, internal textile portion superimposed at least in part with the main, respectively additional, external textile portion of the external textile tubular element. In one embodiment, the external tubular textile element, in particular the external textile part covering at least part of the foot, comprises: - one or more heat-melted textile portion(s), in particular one or more heat-fusible yarn(s) at least partially heat-melted during the manufacture of the shoe; and / or - one or more non-thermally fused multifilament yarns and / or one or more spun fibers, in particular non-thermally fused, more particularly polyester and / or recycled fibers, for example PET (polyethylene terephthalate) or PBT (polybutylene terephthalate); and / or - one or more elastic threads, particularly made of elastane; and / or - one or more transparent and / or translucent monofilament yarn(s), in particular not heat-fused, arranged in the main, respectively additional, external textile portion substantially superimposed with the main, respectively additional, internal textile portion of the internal textile tubular element. In one embodiment, the internal textile tubular element and / or the external textile tubular element each comprise in the region encircling all or part of the foot insertion opening one or more elastic threads, in particular said region does not comprise any heat-fused textile portion. In one variant, the internal, or external, textile tubular element, in particular the internal, or external, textile part covering at least part of the foot, comprises in its forefoot region extending between the medial and lateral sides and / or in the instep area, one or more lacing loop(s) of unitary textile construction, in particular knitted, with the internal, or external, textile tubular element, in particular with the internal, or external, textile part covering at least part of the foot. Advantageously, when the lacing loops are arranged on the internal textile tubular element, the external textile tubular element includes, in its forefoot region extending between the medial and lateral sides and / or in the instep area, one or more through-receiving opening(s) configured to allow the passage of said lacing loop(s) through said through-receiving opening(s) so as to project out of said through-receiving opening(s). In one embodiment, a lacing loop is delimited by two through openings, particularly of a single textile construction, especially knitted, with the internal, or external, tubular textile element respectively. Said two openings are preferably located in the forefoot region extending between the lateral and medial sides and / or in the instep area. For example, a lacing loop is a knitted bridge. In particular, the instep area and / or the forefoot region extending between the lateral and medial sides of the inner and outer textile tubular elements, respectively, comprise first and second sets of through-lace openings. Each of the first and second sets of through-lace openings comprises several, for example, between three and six, sets of two openings, the two openings in each set being separated by a knitted portion forming first or second bridges. More specifically, the first and second bridges of the first and second sets of through-lace openings, respectively, are arranged in a transverse direction T substantially perpendicular to the longitudinal axis L of the inner and outer textile tubular elements. In one embodiment, a lacing loop is formed by a woven knitted yarn, said loop projecting from the external face, in particular from the forefoot region arranged between the lateral and medial sides and / or the instep area, of the external, respectively internal, textile tubular element. In one embodiment, the transparent and / or translucent monofilament filament(s) is / are not thermally melted. Advantageously, the areas where the yarn(s) intersect, particularly the stitches knitted with said yarn(s), are mobile relative to one another. This arrangement provides flexibility to the main outer textile portion and improves permeability. This main outer textile portion thus allows heat and / or perspiration to escape. In one variant, at least one yarn selected from the transparent and / or translucent monofilament yarn(s) of the main external textile portion comprises a thermoplastic elastomer, in particular an olefinic thermoplastic elastomer. Knitting monofilament yarn, especially transparent and / or translucent yarn, on a circular knitting machine is difficult because the monofilament yarn must conform to the curvature of successive knitted loops as well as the tubular shape of the textile element. If the monofilament yarn is not suitable, it tends to break on the knitting machine and / or create a different tension on the tubular element compared to a multifilament yarn, resulting in an irregular appearance. In addition, this monofilament yarn is combined with at least one yarn that is at least partially heat-fusible in a knitted tubular element, which knitted tubular element undergoes a thermoforming or thermocompression step. A monofilament yarn that is too stiff and / or too thick will not provide satisfactory results. Indeed, the knitted tubular element shaped by thermoforming or thermocompression with an unsuitable monofilament yarn does not have an aesthetically pleasing and uniform appearance, which can also create discomfort for the wearer. Advantageously, the use of a transparent and / or translucent monofilament yarn in a thermoplastic elastomer helps to obtain a regular textile tubular element, suitable for thermoforming or heat-pressing to manufacture a shaft that maintains a uniform appearance. Furthermore, this monofilament yarn allows for loose knitting, i.e., without applying significant tension, which facilitates the thermal shrinkage step described below. Preferably, the thermoplastic elastomer(s), in particular olefinic, represents at least 50% by mass, more preferably at least 80% by mass, preferably at least 90% by mass, of the total mass of said at least one monofilamentary yarn. In this text, an olefinic thermoplastic elastomer means any elastomer comprising olefinic repeating units, particularly those based on propylene and / or ethylene. The aforementioned olefinic thermoplastic elastomer can be selected from: - polyisobutylenes (PIB); and / or - ethylene, propylene, and diene terpolymers (EPDM); ethylene and propylene copolymers; ethylene and alpha-olefin copolymers, for example ethylene and butene copolymers or ethylene and octene copolymers, and a mixture thereof; preferably EPDM and ethylene and propylene copolymers; and / or - mixtures of a polyolefin, in particular polypropylene, with one or more non-vulcanized olefinic thermoplastic elastomers, and possibly one or more plasticizers (e.g., mineral, naphthenic, or paraffinic oil(s)); and / or - The said thermoplastic olefinic elastomer(s) may be ethylene-propylene copolymers, ethylene-propylene-diene terpolymers, or ethylene-alpha-olefin copolymers (e.g., ethylene-butene copolymers or ethylene-octene copolymers). The at least one transparent and / or translucent monofilament yarn may comprise one or more thermoplastic elastomers. In one embodiment, at least 80% by mass, preferably about 100% by mass, of said main external textile portion is formed of one or more monofilamentary filament(s) comprising (each) one or more thermoplastic elastomer(s), in particular one or more olefinic thermoplastic elastomer(s). Advantageously, this diameter range allows the said monofilament yarn to be knitted on a circular knitting machine, and to obtain a regular stem.

In one embodiment, said outer main textile portion, and optionally said inner main textile portion, is / are located in at least one of the following upper regions: a forefoot region extending laterally and / or a forefoot region extending medially; an instep area; a forefoot region extending between the lateral and medial sides; a midfoot region extending laterally and / or a midfoot region extending medially; a heel region extending laterally and / or a heel region extending medially; a heel region extending between the medial and lateral sides, or a combination thereof, preferably a forefoot region extending laterally and / or a forefoot region extending medially; and / or an instep area; and / or a forefoot region extending between the lateral and medial sides;a midfoot region extending on the lateral side and / or a midfoot region extending on the medial side; Advantageously, the main external textile portion occupies at least 10%, preferably at least 20% or 30% or 40% or 50% or 60% or 70% or 80%, of the external face of the stem or of the external face of the textile part covering at least part of the foot of the external textile tubular element. In one embodiment, said main internal textile portion is disposed in at least one of the following upper regions: a forefoot region extending laterally and / or a forefoot region extending medially; a forefoot region extending between the lateral and medial sides; an instep area; a midfoot region extending laterally and / or a midfoot region extending medially; a heel region extending laterally; and / or a heel region extending medially; a heel region extending between the medial and lateral sides, or a combination thereof, preferably a forefoot region extending laterally and / or a forefoot region extending medially; and / or an instep area; and / or a forefoot region extending between the lateral and medial sides;a midfoot region extending on the lateral side and / or a midfoot region extending on the medial side; Advantageously, the main internal textile portion occupies at least 10%, preferably at least 20% or 30% or 40% or 50% or 60% or 70% or 80%, of the external face of the stem or of the external face of the textile part covering the foot of the internal textile tubular element. In one embodiment, the external textile tubular element is a knitted sock comprising a foot-receiving cavity, and the internal textile tubular element is a knitted sock positioned at least partially in the receiving void of the foot of the external textile tubular element. Advantageously, the knitted sock, from the internal or external tubular textile element, includes a heel area, a toe end, in particular closed by a seam or weld, and an opening for the introduction of the foot. Advantageously, the internal and external textile tubular elements are at least partially overlapped. In one embodiment, the internal and external textile tubular elements are two separate knitted pieces. This arrangement facilitates differentiation, particularly regarding dimensions and / or configurations (for example, the arrangement of an additional knitted pocket of unitary knitted construction with a knitted textile tube element), between the internal and external textile tube elements, respectively, and the external and internal textile tube elements, respectively. In one embodiment, both the external and internal textile tube elements are of unitary textile construction. Advantageously, the internal and external textile tubular elements are in a single piece of textile, in particular of unitary textile construction, more particularly of unitary knitted construction. Preferably, said part has a general U-shape before folding of the internal textile tubular element into the foot-receiving volume of the external textile tubular element (in particular this folding is carried out in the shoe manufacturing process according to a second aspect of the invention). Preferably, the inner sock is in a folded position within the foot pocket of the outer sock. The folding of the inner sock into the outer sock begins at the level of their foot insertion openings or at the level of their open toes. In one embodiment, the foot insertion opening, respectively the toe, of the external textile tubular element is in textile connection, in particular knitted, with the foot insertion opening, respectively the toe, of the internal textile tubular element. The folding is therefore done from the opening for inserting the foot or from the toe tip which was opened during the manufacturing process. In one embodiment, the main internal textile portion does not include a thermofused textile portion. Advantageously, the peripheral region of the stem bordering all or part of the main internal and external textile portions overlapping at least in part, comprises one or more heat-fused textile portion(s), in particular securing the internal textile covering part of the foot with the external textile covering part of the foot. In one embodiment, the main internal textile portion comprises one or more non-thermally fused monofilamentary filaments, possibly transparent and / or translucent. Preferably, the said thread(s) form(s) an internal viewing zone, substantially opposite the viewing zone of the main external textile portion (which can be described as the external viewing zone). Advantageously, the internal viewing area allows visualization of the inside of the shoe's reception volume, and therefore the part of the foot opposite said area. In one embodiment, the internal textile tubular element, in particular its internal textile part covering at least part of the foot, comprises one or more thermofused textile portion(s), and the external textile tubular element, in particular its external textile part covering the foot, does not comprise any thermofused textile portion or one or more thermofused textile portion(s) whose total mass is less than or equal to 0.50 times the total mass of the thermofused textile portion(s) of the internal textile tubular element, in particular less than or equal to 0.50 times the total mass of the thermofused textile portion(s) of the internal textile part covering the foot. Advantageously, the external textile tubular element comprises less thermofused textile material than the internal textile tubular element. This arrangement allows for an external tubular element that offers greater flexibility and is more breathable than the internal tubular element. In one embodiment, the main, or additional, external textile portion, and / or the main, or additional, internal textile portion each have one or more textile through-opening(s), in particular knitted, notably with one or more monofilamentary yarn(s) (as described in this text, for example transparent and / or translucent) or with one or more multifilamentary yarn(s). Preferably, the through opening(s) extend(s) between the inner and outer faces of the main, or additional, outer textile portion and / or of the main, or additional, inner textile portion. The main, or additional, external, or internal textile portion may include through-openings: - distributed in a given region of said main portion, or additional portion, for example a given forefoot region of the textile cover part, and / or - encompassing at least part of said main or additional portion in a given region, for example in a midfoot region on the lateral or medial side of the textile cover part, and / or - a region of the stem that is less stressed in tension or shear. The through opening(s) includes (or is / are) one or more through opening(s), in particular at least 3 or 4 or 5 or more than 5 openings through, (each) having at least one dimension greater than or equal to 1 mm or 2 mm or 3 mm or 4 mm or 5 mm or 8 mm, or greater than or equal to 10 mm, in particular the through opening(s) is / are defined as being one or more through opening(s) A. The through opening(s) includes (or is / are) one or more through opening(s), in particular at least 3 or 4 or 5 or more than 5 through openings, (each) having at least one dimension less than or equal to 20 mm or 15 mm or 8 mm or 5 mm or 4 mm or 3 mm or 2 mm or 1 mm, in particular the through opening(s) is / are defined as being one or more through opening(s) A. In a preferred example, the through opening(s) includes (or is / are) one or more through opening(s) having at least one dimension ranging from 3 mm to 15 mm, preferably ranging from about 5 mm to 15 mm, especially of type A. One or more through openings can have any shape, and for example an ovoid, round, parallelepiped shape (for example square or rectangular). The through opening(s) comprises one or more through opening(s), in particular at least 3 or 4 or 5 or more than 5 or more than 30 through openings, (each) having at least one dimension greater than or equal to 0.1 mm, or 0.5 mm, and less than or equal to 1 or 2 mm, in particular the through opening(s) is / are defined as being one or more B through opening(s). For example, this type of B opening(s) is found on a main, or additional, internal or external textile portion of knitted mesh or honeycomb structure. In a preferred example, the through opening(s) includes (or is / are) one or more through opening(s) having at least one dimension ranging from 0.1 mm to 2 mm, preferably ranging from about 0.8 mm to 2 mm, especially of type B. Advantageously, the through opening(s), in particular A and / or B, is / are knitted with one or more transparent and / or translucent monofilament yarn(s), in particular non-thermally fused, or one or more multifilament yarn(s), in particular non-thermally fused. This arrangement allows for the formation of tear-resistant through-openings. This arrangement also improves flexibility, breathability and enhances the display / viewing function of the main, or additional, outer textile portion, respectively inner. In a first example of embodiment, the main, or additional, external textile portion does not include a through opening and the main, or additional, internal textile portion includes one or more through opening(s), in particular A and / or B, more particularly B. Advantageously, the opening(s) through the main, or additional, internal textile portion is / are knitted with one or more multifilamentary yarn(s).

The arrangements of the first and second examples above advantageously improve the tear resistance of the stem since the through opening(s) arranged in the internal textile tubular element are covered by the external textile tubular element, in particular said internal textile tubular element not including a through opening. In a second embodiment, the main, or additional, internal textile portion does not include a through opening and the main, or additional, external textile portion includes one or more through opening(s), in particular A and / or B, more particularly A.

In an alternative embodiment, the main, or additional, external textile portion includes one or more through openings that are not opposite any through openings of the main, or additional, internal textile portion. This design helps protect the foot placed inside the shoe's cavity from, for example, rain, dust, particles, etc. In one embodiment, the main internal and external textile portions are disposed at least in part, in particular entirely, in the midfoot region extending on the lateral side of the upper, and the internal textile tubular element further comprises an additional internal textile portion and the external textile tubular element comprises an additional external textile portion, the additional internal and external textile portions are superimposed at least in part and disposed at least in part, in particular entirely, in the midfoot region on the medial side of the upper, the additional external textile portion comprises one or more transparent and / or translucent monofilamentary yarn(s), in particular non-thermally fused, forming a viewing area of ​​the additional internal textile portion. In one sub-embodiment, the upper further comprises another additional internal textile portion and another additional external textile portion which are superimposed at least in part and disposed at least in part, in particular entirely, in the forefoot region disposed between the lateral and medial sides and possibly in the forefoot region disposed on the lateral side and / or the forefoot region disposed on the medial side. In one embodiment, the main, or additional, external textile portion includes an inner face portion and the main, or additional, internal textile portion includes an outer face portion that is not integral with the inner face portion of the main, or additional, external textile portion, in particular that is not glued to the inner face portion of the main, or additional, external textile portion, in particular that is not glued by a thermofused textile portion. In one embodiment, the main, or additional, external textile portion comprises one or more translucent and / or transparent monofilamentary yarn(s), each having a trilobed cross-section, and preferably a linear mass greater than or equal to 20 denier and less than or equal to 60 denier. The inventors determined that this arrangement makes it possible to implement said monofilament yarn on a textile machine, in particular by knitting, while offering a good compromise between rigidity and flexibility. In addition, this type of thread adds shine. In this text, a trilobed cross-section means that the cross-section of a monofilamentary wire includes at least three sides. Advantageously, a trilobed cross-section has a generally triangular shape. The present invention relates, according to a second aspect, to a method for manufacturing a shoe, in particular a sports shoe, notably according to any one of the embodiments according to a first aspect of the invention, said method advantageously comprising the steps: i) an external textile tubular element and an internal textile tubular element are provided, at least one of said internal and external textile tubular elements comprising at least one heat-fusible textile portion, the external textile tubular element comprising at least one main external textile portion and the internal textile tubular element comprising at least one main internal textile portion, the internal textile tubular element is disposed at least in part in a void for receiving the foot of the external textile tubular element such that said external and internal textile tubular elements are at least partially superimposed,and that the main internal and external textile portions are at least partially superimposed, the main external textile portion comprising a, or several transparent and / or translucent monofilamentary filaments, in particular having a melting temperature Tf or degradation temperature Td; ii) the internal and external textile tubular elements are heated to a heating temperature Te so as to melt at least partially said at least one thermofusible textile portion, in particular the temperature Tf or Td is greater than the heating temperature Te; iii) a rod is obtained comprising at least a part of the external textile tubular element and at least a part of the internal textile tubular element, at least one of said internal and external textile tubular elements comprising at least one thermofused textile portion, and said at least one main external textile portion forms a viewing zone of the main internal textile portion. In one example, the process includes a step of attaching a sole structure to the external textile part of the sole of the external textile tubular element or to the upper obtained in step iii). In one example, the process includes a thermoforming or thermocompression step during which one or more sole element(s) can be disposed between the inner textile part of the sole of the inner textile tubular element and the outer textile part of the sole of the outer textile tubular element or in contact with the textile part of the sole of the outer textile tubular element, in particular for bonding, more particularly by bonding with one or more thermomelted textile portion(s). The thermoforming step, particularly the heating step (ii), advantageously includes the heat-fixing of the inner and outer textile coverings, at least partially, of the foot of the inner and outer textile tubular elements to the shape of a preform generally shaped like a foot. The inner and outer textile tubular elements are held under pressure against the preform during cooling so as to conform to and retain its shape. The wire(s) that are at least partially heat-fusible may be bonded together. The preform in the general shape of a foot is preferably arranged in the receiving volume of the foot of the internal textile tubular element, the textile tubular elements being superimposed at least in part. The thermocompression step, in particular the heating step (ii), advantageously comprises arranging the inner and outer textile tubular elements, with one or more sole element(s), in a mold. Preferably, an inflatable bladder (in particular made of silicone), especially one having a shape substantially resembling a foot, is arranged in the foot-receiving volume of the inner textile tubular element, which inner textile tubular element is at least partially superimposed on the outer textile tubular element. During thermocompression, the inflatable bladder is inflated, for example, to a pressure of Inflation, ranging from approximately 3 to 6 bars, is used to compress the internal and external textile tubular elements, and possibly the sole element(s), against the inner face of the mold. The mold may be in two or three parts. For example, two mold parts are configured to receive and mold the upper, and one mold part is configured to receive and mold the sole structure. The heating temperature during thermocompression is determined to melt and induce flow to a greater or lesser degree in the targeted heat-fusible textile material(s). Indeed, the shoe may include one or more textile materials that are inherently heat-fusible, but which are not heat-melted during the shoe's manufacture. This textile material is thus considered non-heat-fusible or non-heat-melted according to the invention. For example, the heating temperature is greater than or equal to 110°C and less than or equal to 200°C, in particular ranges from 110°C to 160°C. An internal or external tubular textile element can be knitted on a small-diameter circular knitting machine. It can be knitted using either a picked-stitch or a dropped-stitch technique, preferably with picked-stitch. After step (iii), the process may include a step of attaching one or more sole element(s) to the external textile part of the sole of the external textile tubular element, for example portions of rubber joined by gluing. It is also possible to screw metal spikes into protrusions projecting from the outer face of the outer textile part of the sole of the outer textile tubular element to form cleats. The sole element which can be placed between the internal and external textile parts of the sole and the internal and external tubular textile elements respectively is a wear sole or a cushioning element, for example having a Shore A hardness greater than 30 and less than 80. In one variant, at least the outer textile tubular element, in particular the outer textile tubular element and the inner textile tubular element, undergoes a thermal shrinkage step before step ii). In one variant, at least one yarn chosen from the transparent and / or translucent monofilament yarn(s) of the main external textile portion comprises one or more thermoplastic elastomer(s), in particular one or more olefinic thermoplastic elastomer(s). In one variant, at least one yarn chosen from the transparent and / or translucent monofilament yarn(s) of the main external textile portion is selected so as to have a thermal shrinkage rate greater than or equal to 5%, preferably greater than or equal to 7%, more preferably less than or equal to 20%, preferably less than or equal to 15%. This provision allows the thermal shrinkage of the monofilament yarn to be activated during the thermal shrinkage step which takes place before step ii) of thermoforming or thermocompression. Advantageously, the main outer textile portion, and optionally one or more other portions of the outer and / or inner textile tubular element, is / are knitted with one or more transparent and / or translucent monofilament yarns under low tension during knitting, i.e., in a "loose" manner. Furthermore, said transparent and / or translucent monofilament yarn(s) exhibit a significant (dimensional) shrinkage rate. Advantageously, the thermal shrinkage step allows the dimensional shrinkage (%) of the transparent and / or translucent monofilamentary yarn(s) to be activated, and thus to obtain an external main textile portion, and possibly in general an external textile tubular element and / or an internal textile tubular element depending on the arrangement of the transparent and / or translucent monofilamentary yarn(s), which has a regular knitted surface, and a shape adjusted to the preform, before step ii) of thermoforming and / or thermocompression. Advantageously, the thermal shrinkage step includes the application of heat to at least said external textile tubular element for a determined period in order to obtain the desired dimensional shrinkage of said external textile tubular element, and optionally of said internal textile tubular element, for example includes the application of hot water (for example at 80°C) or steam, for at least 5 seconds, for example for a period of 30 seconds to 5 minutes. The shrinkage (%) of said at least one yarn or of the external and / or internal textile tubular element(s) is evaluated by the following calculation: [(length of a zone A, taken in the weft direction or in the direction of the mesh columns, located in the main external / internal textile portion before the thermal shrinkage step; or called initial length) - (length of said zone A taken in the weft direction or of the retained mesh columns, located in the main external / internal textile portion after the thermal shrinkage step; or called activated length)] / (initial length) * 100. Advantageously, the shrinkage measured on the transparent and / or translucent monofilament thread is greater than or equal to 5%. Advantageously, the shrinkage measured on an area A of said external textile tubular element is greater than or equal to 5%. The definitions, variants, examples and embodiments according to a first aspect of the invention apply independently of each other to the second aspect of the invention.

Description of the implementation methods For the purpose of referencing the terminology used in this text and associated with a shoe, the shoe 10 shown in Figure 1 will be described below. The shoe 10 can be divided into three general regions: a forefoot region 12, a midfoot region 14, and a heel or hindfoot region 16. The forefoot region 12 generally includes parts of the shoe 10 corresponding to the toes and the joints connecting the metatarsals to the phalanges. The midfoot region 14 generally includes parts of the shoe 10 corresponding to the arch of the foot. The heel or hindfoot region 16 generally corresponds to the rear parts of the foot and includes, in particular, the calcaneus bone.The shoe 10 also includes a lateral side 17 and a medial side 18, which extend across each of the forefoot 12, midfoot 14, and heel 16 regions and correspond to the opposite sides of the shoe 10. More specifically, the lateral side 17 corresponds to an outer area of ​​the foot, and the medial side 18 corresponds to an inner area of ​​the foot. The shoe 10 includes a foot entry opening 5 for accessing the foot reception (or support) volume 6. The shoe 10 includes an instep area 11 extending substantially centrally between the lateral side 17 and the medial side 18 in the midfoot region and possibly partially into the forefoot region 12. The shoe 10 also includes a longitudinal axis L and a transverse axis T, in particular substantially perpendicular to the axis L. The shoe 10 also includes a front edge 19a and a rear edge 19b. The footwear article 10 includes an upper 15 and a sole structure, including an outsole 20. In addition to the shoe 10, the forefoot region 12, the midfoot region 14, the heel region 16, the lateral side 17, the medial side 18, the front edge 19a, the rear edge 19b, the instep area 11, the foot entry opening 5, and the foot reception or accommodating volume 6, may apply to the sole structure 20, the upper 15, and their individual elements, such as, for example, but not limited to, the internal and external textile tubular elements and their respective textile foot covering parts and their respective textile sole parts. Figure 2 schematically represents, for reference purposes, the different regions that a footing structure 20 can comprise, corresponding to the regions defined in Figure 1. Figure 3 schematically represents a first example of a distinct internal textile tubular element 50 and a first example of a distinct external textile tubular element 60, each within a knitted textile piece, in particular each within a knitted sock. The internal textile tubular element 50 comprises an internal foot covering textile portion 52 and an insole textile portion 54, as well as an angled portion 56 forming a heel region. In this specific example, the internal foot covering textile portion 52 extends into the forefoot, midfoot, and heel regions, from the lateral to the medial side. In this specific example, the insole textile portion 54 extends between a front edge and a rear edge into the forefoot, midfoot, and heel regions, from the lateral to the medial side. The external textile tubular element 60 comprises an external textile foot cover portion 62 and an external textile sole portion 64, as well as an angled portion 66 forming a heel area. In this specific example, the external textile foot cover portion 62 extends into the forefoot, midfoot, and heel areas, between the lateral and medial sides. In this specific example, the textile portion of the external sole 64 extends between the front edge and a rear edge in the forefoot, midfoot, and heel areas, between the lateral and medial sides. The internal textile tubular element 50 is arranged within the receiving volume 61 of the external textile tubular element 60, so that they are substantially superimposed, at least partially. The internal 50 and external 60 textile tubular elements are preferably placed on a foot-shaped preform (in particular, the preform is arranged within the receiving volume of the foot of the internal textile tubular element 50), and then undergo a thermoforming or thermocompression step during which the heat-fusible textile portions of said internal 50 and 60 textile tubular elements are thermally melted so as to bond the internal 50 textile tubular element to the external 60 textile tubular element, and to shape the assembly to the foot-shaped preform. The internal 50 and external 60 textile tubular elements are then cooled on the preferred preform to solidify said shape. During the thermoforming stage, the preform is preferably rigid. During the thermocompression stage, the preform is an inflatable bladder (particularly made of silicone or polyurethane material that can be inflated and deflated, and is therefore reusable). The heating temperature applied during the thermocompression stage is determined to melt the targeted hot-melt material(s) more or better. Thus, depending on the desired effects, threads can be bonded between... They and / or threads can form a film or a coating, for example, covering the internal textile tubular element 50, or the external textile tubular element 60. One or more sole elements, for example an outsole or a flexible sole element made of a material having a Shore A hardness between 40 and 70, is / are arranged between the textile part of the insole 54 and the textile part of the outsole 64. Preferably, the inner sole textile parts 54 and outer sole parts 64 are made essentially of heat-fusible yarn(s) or each comprises at least 80% by mass of its total mass of heat-fusible yarn(s). Preferably, during the thermocompression step, the at least partially or entirely heat-fusible yarn(s) of the inner and outer textile sole parts (54, 64) are thermally melted. Since the inner and outer textile tubular elements 50 and 60 are preferably separate knitted pieces, they can have different configurations. For example, as shown in Figure 3, the outer textile foot cover part 62 covers less of the foot than the inner foot cover part 52; in particular, the outer textile foot cover part 62 does not include an instep area and covers less of the ankle than the inner textile cover part 52. Figure 4 schematically represents a second example of an internal textile tubular element 70 and a second example of an external textile tubular element 80, both of unitary textile construction, specifically in a single U-shaped knitted piece. In this particular example, the internal and external textile tubular elements 70 and 80 are joined by a knitted textile connection at their foot insertion openings, corresponding to the fold line 75 from which the internal tubular element 70 is inserted into the foot 85 of the external textile tubular element 80. The internal 70 and external 80 textile tubular elements are advantageously knitted socks, and each has a bent portion 72, 82. The internal and external textile tubular elements 70,80 are arranged on a foot-shaped preform (not shown), in particular the preform is arranged in the receiving volume of the foot of the internal textile tubular element 70. The internal textile tubular elements 70 and external textile elements 80 then undergo a thermoforming or thermocompression step during which thermofusible textile portions are thermomelted to bond the said internal and external textile tubular elements 70,80 together and form them to the shape of the preform. The textile portion of the insole 54 or 72, and the textile portion of the outsole 64 or 82, are shown in Figures 3 to 5 as configured to lie strictly under the foot. In another example, depending on the configuration of the sole structure chosen, the textile portion of the insole 54 or 72, and / or the textile portion of the outsole 64 or 82, wraps around part of the top of the foot, either entirely or partially. around the foot. The thermocompression step can take place as described with reference to the first examples of internal and external textile tubular elements (50,60). Figures 6 to 12 below essentially describe different examples of configurations of the internal and external textile tubular elements, in particular different configurations of the main superimposed internal and external textile portions, according to the invention. Figure 6 schematically represents a shoe 100 comprising an upper 110 and a sole 120. The shoe 100 includes an internal textile tubular element 130 disposed at least in part within the foot-accommodating volume of an external textile tubular element 140. The upper 110 includes the internal textile foot-covering portion 132 of the internal textile tubular element 130 and the external textile foot-covering portion 142 of the external textile tubular element 140. Advantageously, the outer textile covering portion of the foot 142 comprises a main outer textile portion 144 extending partly into the forefoot region located between the medial and lateral sides and the forefoot regions located on the lateral and medial sides, and partly into the midfoot regions located on the medial and lateral sides. In particular, the main outer textile portion 144 does not extend into the instep area 102. Advantageously, the main outer textile portion 144 occupies at least 50%, preferably at least 80%, of the total area occupied by the forefoot and midfoot regions of the outer textile covering portion of the foot 142. The main outer textile portion 144 comprises, in particular, essentially transparent monofilament yarns forming a substantially continuous viewing area extending into said regions.The said monofilamentary yarns are, in a non-limiting example, transparent polyethylene terephthalate monofilamentary yarns having a diameter of approximately 0.50 mm. Advantageously, the main external textile portion 144 includes through-holes 146, in particular through-holes A as defined above, each particularly having at least one dimension da greater than or equal to 2 or 3 mm. These through-holes 146 are preferably knitted at the same time as the external tubular textile element 140. Advantageously, the inner textile covering portion of the foot 132 comprises a main inner textile portion 134 partially overlapping the main outer textile portion 144. In this example, the main inner textile portion 134 does not include a through opening. Advantageously, the inner textile covering portion of the foot 132 comprises a main inner textile portion 134 that extends at least partially into the forefoot regions located between the lateral and medial sides and on the lateral and medial sides, as well as into the midfoot regions on the lateral and medial sides. The inner textile covering portion of the foot 132 also extends into the instep area 102. The instep area 102 of the inner textile covering portion of the foot 132 thus forms part of the outer face of the upper 110. Advantageously, the main inner textile portion 134 occupies at least 50%, preferably at least 80%, of the total surface area occupied by the forefoot and midfoot regions located on the lateral and medial sides, and the forefoot region located between the lateral and medial sides, of the inner textile covering portion of the foot 132. The main inner textile portion 134, in particular its outer face 134b, is visible from the outer face 144b of the main outer textile portion 144. In particular, the color (here gray) and the textured appearance of the textile of the main inner textile portion 134 are visible from the viewing area formed by the main outer textile portion 144. Figure 7 schematically represents a third example of an internal textile tubular element 200 arranged partly in the receiving volume of a foot of a third example of an external textile tubular element 250. The external textile tubular element 250 includes an external foot covering textile portion 260 comprising a main external textile portion 270 consisting essentially of transparent monofilamentary yarns and extending in part in the forefoot and midfoot regions on the lateral and medial sides, and in the forefoot region between the lateral and medial sides, of the external foot covering textile portion 260. Said monofilamentary yarns are in a non-limiting example transparent polyethylene terephthalate monofilamentary yarns having a diameter of the order of 0.35 mm, not intended to be heat-melted. The internal textile tubular element 200 includes an internal textile foot cover portion 210 comprising a main internal textile portion 220 extending partly into the forefoot and midfoot regions on the lateral and medial sides, and in the forefoot region between the lateral and medial sides, of the internal textile foot cover portion 210. In this specific example, the main internal textile portion 210 comprises knitted meshes separated by gaps forming through-openings, in particular through-openings B as described above, each having at least one dimension on the order of approximately 1 mm or less. The main external textile portion 250 thus forms a viewing area for the outer face of the first internal textile portion 210. It is possible to visualize the color, pattern(s), and knitted texture of the main internal textile portion 210. In this specific example, the outer main textile portion 270 does not contain heat-fused yarns, allowing the knitted stitches within it to move freely relative to one another, as the monofilament yarn can slide within these stitches. The outer main textile portion 270 thus retains a degree of flexibility and breathability, enabling the evacuation of perspiration and accumulated heat between the inner and outer main textile portions (210, 270), and within the foot's support area. In this specific example, the main external textile portion 270 is represented with a single type of mesh pattern (i.e., the way the yarns are joined together) that is repeated across its entire surface. However, the main external textile portion 270 can include different mesh patterns arranged in distinct areas. In this specific example, the external textile tubular element 250 comprises two sets 251, 252 of knitted tubes 255, 256 arranged respectively on either side of the instep area 210. The knitted tubes 255 arranged on the lateral side of the instep area cooperate with the knitted tubes 256 arranged on the medial side of the instep area to receive, for example, a lace. The knitted tubes 255, 256 are of a single knitted construction with the external textile tubular element 250, which is also knitted. In this specific example, the external textile tubular element 260 comprises a single main external textile portion 270. However, the external textile tubular element 260 could comprise one or more separate additional external textile portion(s), in particular the main external textile portion and the additional external textile portion(s) are separated from each other by one or more intermediate external textile portion(s) not comprising transparent and / or translucent monofilamentary yarn(s). By way of non-limiting example, the external textile covering part of the foot 260 includes heat-fusible knitted textile portions 262 which will be melted during the thermocompression step, preferably in mixture with non-heat-fusible knitted textile portions. Preferably, the inner and outer textile sole parts are made up essentially of hot-melt thread(s) which is / will be hot-melted during the thermocom pressure step. Hot melt wires are, in a non-limiting example, multifilament single-component polyurethane wires, in particular having a linear mass between 50 dtex and 80 dtex, and the number of filaments between 30 and 45 filaments. Figure 8 schematically represents a fourth example of an internal textile tubular element 300 disposed partly within the receiving volume of a foot of an external textile tubular element 350. The external textile tubular element 350 comprises an external textile covering portion of the foot 360 including a main external textile portion 370 made essentially of transparent monofilament yarns and extending partly into the forefoot and midfoot regions on the lateral and medial sides, and into the forefoot region between the lateral and medial sides, of the external textile covering portion of the foot 360. Said monofilament yarns are, in a non-limiting example, transparent polyethylene terephthalate monofilament yarns having a diameter of approximately 0.35 mm, not intended to be heat-melted. The internal textile tubular element 300 includes an internal foot covering textile portion 310 comprising a main internal textile portion 320 disposed in the forefoot and midfoot regions on the lateral and medial sides, and in the forefoot region between the lateral and medial sides, of the internal foot covering textile portion 320. In this specific example, the main internal textile portion 310 includes knitted through-holes 315, in particular knitted through-holes A as described above, more specifically having at least one dimension on the order of approximately 3-4 mm. The main external textile portion 350 thus forms a viewing area for the outer face of the main internal textile portion 310. It is possible to view the color, pattern(s), knitted texture, and the through-holes 315 of the main internal textile portion 310. The through openings 315 in the main internal textile portion 310 allow visualization of the volume housing the upper 380, particularly the portions of the foot. Figure 9 schematically represents a fifth example of an internal tubular textile element 400 disposed partly within the volume housing the foot of a fifth example of an external tubular textile element 450. The external tubular textile element 450 comprises an external textile covering portion of the foot 460, including a main external textile portion 470 made essentially of translucent monofilament yarns and extending partly into the midfoot region on the lateral and medial sides, and partly into the forefoot region between the lateral and medial sides, of the external textile covering portion of the foot 460. The internal tubular textile element 400 includes an internal foot covering textile portion 410 comprising an internal textile portion 420 extending partly into the midfoot region on the lateral and medial sides, and into the forefoot region between the lateral and medial sides of the internal foot covering textile portion 410. In this specific example, the internal main textile portion 420 includes through-holes, particularly knitted ones, specifically knitted through-holes B as defined above, more particularly having at least one dimension on the order of approximately 1 mm or less. The external main textile portion 470 thus forms a viewing area for the outer face of the internal main textile portion 420. It is possible to view the color, pattern(s), and knitted texture of the internal main textile portion 420. In this specific example, the main external textile portion 470 includes knitted through openings 475 A as defined above in this text, in particular having at least a dimension of about 3 to 5 mm. Advantageously, the through openings 475 of the main external textile portion 470 have at least one dimension greater than at least one of the dimensions of each of the through openings B of the main internal textile portion 420. In this embodiment example, the knitted through-openings are distributed in the forefoot region arranged between the lateral and medial sides, and partially border the main external textile portion 470 in the midfoot regions on the lateral and medial sides. For example, the textile portion covering the outer foot 460 includes first and second sets 462, 463 of through-openings 476 forming lacing loops or textile bridges 477 in the instep area. A lacing loop 476 is delimited by two adjacent through-openings 476 arranged transversely with respect to the longitudinal axis of the outer textile tubular element 450. The through-openings 476 are of unitary textile construction, in particular knitted, with the outer textile tubular element 450. In Figure 9, the main external textile portion 470 extends substantially continuously in the forefoot and midfoot regions. Alternatively, the main external textile portion 470 could be located solely in the forefoot region between the lateral and medial sides, and the external tubular textile element 450, particularly its external covering textile portion 460, could include a first additional external textile portion located in the midfoot region on the lateral side and a second additional external textile portion located in the midfoot region on the medial side. In this case, the main and additional external textile portions are distinct from each other and optionally separated by one or more intermediate textile portions not comprising transparent monofilament yarn. The same alternative arrangement can be used with the internal tubular textile element 410. Figures 10 and 11 schematically represent a sixth example of an internal textile tubular element 500 disposed partly in the receiving volume of a foot of an external textile tubular element 550. The external textile tubular element 550 comprises an external foot covering textile portion 560 including a main external textile portion 570 consisting essentially of transparent monofilament yarns and extending partly into the forefoot, midfoot and hindfoot regions, and this on and between the lateral and medial sides, of the external foot covering textile portion 560. The internal tubular textile element 500 includes an internal foot covering textile portion 510 comprising a main internal textile portion 520 extending partly into the forefoot, midfoot and heel regions, and this on and between the lateral and medial sides, of the internal foot covering textile portion 510. In this specific example, the main internal textile portion 510 includes through-holes, in particular through-holes B as defined above, more specifically having at least one dimension on the order of approximately 1 mm. The main external textile portion 550 thus forms a viewing area of ​​the external face of the main internal textile portion 510. It is possible to view the color, pattern(s), and texture, including knitted, of the main internal textile portion 510. In this specific example, the main external textile portion 570 includes through openings 575, in particular through openings A as defined above, more particularly having at least one dimension of about 3 to 5 mm, and having at least one dimension greater than at least one of the dimensions of the through openings of the main internal textile portion 510. In this specific example, the through openings 575 are arranged in the forefoot, midfoot and heel regions, and this on and between the lateral and medial sides of the external textile covering part of the foot 560. Preferably, the textile parts of the insole 530 and outsole 580 are made primarily of single-component, heat-fusible multifilament yarns, particularly heat-fusible polyurethane. These yarns are therefore heat-fused onto the finished shoe. Figure 12 schematically and partially represents a third example of a shoe according to the invention 700 comprising an internal tubular textile element 705 disposed partly in the volume of a foot of the external tubular textile element 750. The external textile tubular element 750 includes an external foot covering textile portion 760 comprising a main external textile portion 770 consisting essentially of transparent monofilamentary yarns and extending partly into the forefoot and midfoot regions; and this on and between the lateral and medial sides. The internal tubular textile element 705 includes an internal foot covering textile portion 710 comprising a main internal textile portion 720 also consisting essentially of transparent monofilament yarns and extending partly into the forefoot and midfoot regions; and this on and between the lateral and medial sides. The said monofilamentary wires are, in a non-limiting example, transparent polyethylene terephthalate monofilamentary wires having a diameter of approximately 0.35 mm, not intended to be heat-melted. In this specific example, the main external and internal textile portions 720,770 can each include through-openings according to the selected mesh patterns, in particular through-openings B as defined above, more particularly having at least a dimension of 1 mm or less. The outer textile portion 770 forms a viewing area for the inner textile portion 720. The inner textile portion 720 forms a viewing area for the foot's accommodating volume. It is possible to see the inside of the shoe in this configuration. Figures 13 and 14 schematically represent a fourth example of a shoe 800, particularly a sports shoe, according to the invention comprising an external tubular textile element 850 and an internal textile tubular element 805 folded into the receiving volume of the foot of the external textile tubular element 850. In this example, the external textile tubular element 850 comprises an external foot covering textile portion 860, i.e., all or part of the upper part of the foot, and a sole portion (not visible) covering all or part of the underside of the foot. The external textile tubular element 850 comprises a main external textile portion 870 knitted with a transparent monofilament yarn, said main external textile portion 870 extending partly into the forefoot and midfoot regions located on the lateral (810, 815) and medial (820, 825) sides, and partly into the forefoot region located between the lateral and medial sides 830 of the external foot covering textile portion 860.Said transparent monofilament wire preferably has a diameter of about 0.15 mm, and is in an olefinic thermoplastic elastomer, in particular based on propylene and ethylene, having a shrinkage rate of about 9% (shrinkage conditions tested: heating at 180°C for 2 minutes). In this example, the internal textile tubular element 805 comprises knitted through-openings 880 made with one or more multifilament yarns, arranged in the internal textile covering portion of the foot 806, in particular all or part of the instep, in the forefoot and midfoot regions located on the lateral and medial sides, and partly in the forefoot region located between the lateral and medial sides of said internal textile covering portion of the foot. In particular, the through-openings 880 have at least one dimension greater than or equal to approximately 10 mm, for example, approximately 10-12 mm. Each of the medial and lateral regions in this specific example comprises seven through-openings. These through-openings, given their size, are of type A as described herein. The forefoot region in this specific example comprises fifteen through-openings.The textile portion 812 of the internal textile tubular element 805 covered by the main external textile portion 870 forms the main internal textile portion. During the upper manufacturing process, the monofilament yarn is loosely knitted. After knitting, the inner textile tubular element 805 is placed within the foot cavity of the outer textile tubular element 850. The overlapping inner and outer textile tubular elements (805, 850) are then placed on a preform shaped like the upper and undergo a thermal shrinkage step, specifically the application of steam for approximately 3 minutes, to activate the dimensional shrinkage of the transparent monofilament yarn. Next, the overlapping textile tubular elements undergo a thermoforming step (ii) to conform to the shape of the preform, thereby melting or softening the heat-fusible textile components provided by the at least partially heat-fusible yarns. The overlapping tubular elements (805, 850) on the preform are allowed to cool to solidify the shape, and the resulting upper 890 is then assembled with a sole 895. In this specific example, the internal textile tube element 805 comprises a set of knitted loops 808 arranged in the instep area of ​​the upper 890, and the external textile tube element 850 comprises a set of through-holes 855 arranged in the instep area of ​​the upper 890, through which said loops 808 extend. The loops advantageously form lacing areas for the passage of a shoelace. Advantageously, the through-holes 880 are protected by the external textile tube element 850, which covers them, in particular by the outer monofilament main textile portion 870, which is transparent and abrasion-resistant. Furthermore, these through-holes 880 can be seen by the wearer, which contributes to a distinctive appearance.Advantageously, the permeability of the upper of the 800 shoe is improved compared to a similar shoe lacking the through-holes of the 880 and monofilament yarns. The permeability of the textile complex comprising the superimposed internal and external tubular textile elements (805, 850), measured in the forefoot region, is approximately 1043.8 l / m. 2 / s while the permeability of a comparative complex not including through-holes or monofilament wires is 439.2 m / m 2 / s. Permeability is determined according to ISO 9237-1995. The through openings are thus advantageously protected from tearing, considerably improve the permeability of the shoe and therefore the evacuation of heat and perspiration, and are visible from the outside of the shoe, thus facilitating understanding of the functioning of the shoe. Advantageously, the elongation of the upper of shoe 800 is improved compared to a similar shoe without the through-holes 880 or monofilament yarns. The elongation of the textile complex comprising the superimposed internal and external tubular textile elements (805, 850) under a force of 15 Newtons is approximately 17.25 mm, while the elongation of a comparative complex without through-holes or monofilament yarns is 10.8 mm. Elongation is determined in a room with a temperature of approximately 20°C + / - 2°C, a relative humidity of 65% + / - 4%, a test sample with a length of 150 mm and a width of 50 mm, a tensile testing machine speed of 200 mm / min, and a jaw width of 100 mm. The measured elongation corresponds to that obtained after two tensile cycles. The test can be performed on a tensile testing bench adapted for textiles and sold by Instron. Advantageously, the elongation of the rod according to the invention is advantageously improved by about 60% when monofilamentary wires, which are by definition more rigid than multifilamentary wires, are used. Figures 15 and 16 schematically represent a fifth example of a shoe 900, particularly a sports shoe, according to the invention comprising an external tubular textile element 950 and an internal tubular textile element 905 folded into the foot-accommodating volume of the element The 950 outer textile tubular upper is similar to the 800 shoe. The 900 shoe differs from the 800 shoe in the lacing system, the ends of a lace being arranged in a loop 910 sewn onto the outer textile covering part of the foot 960. In addition, the main outer textile portion 970 of the outer textile covering part of the foot 960 has a contour without a notch. In one embodiment according to the invention, and as can be seen in the various versions of Figures 7, 8, and 12 to 16, the main external textile portion, for example 970 or 970, is separated from the external textile portion of the sole of the external textile tubular element, for example 850 or 950, by at least one connecting textile portion of said external textile tubular element not comprising monofilament yarn(s), in particular transparent and / or translucent yarn(s), such as, for example, the connecting textile portion 862 or 962. In particular, the connecting textile portion, for example 862 or 962, partially or substantially borders the lower edge, for example 871 or 971, of the main external textile portion, for example 870 or 970. This arrangement strengthens the connection between the upper and the sole structure.
