Description

Technical Field

[0001] The present invention relates to the technical field of footwear, in particular sports shoes, comprising two textile tubular elements for the construction of an upper and optionally a sole of said footwear, and to a method for manufacturing such footwear. Background Art

[0002] Conventional footwear generally includes an upper and a sole structure. The upper is fixed to the sole structure and forms a void inside the footwear to comfortably receive and secure the foot. The sole structure is fixed to the lower area of ​​the upper and is located between the ground and the upper during use.

[0003] In footwear articles used for physical exercise, the sole structure may include an outsole and a midsole. The midsole typically includes a material made of polymer foam that absorbs impact with the ground when impact occurs to reduce the impact on the foot and leg when walking, running or other ambulatory activities. The sole structure may also include a lining positioned proximate to the lower surface of the foot to increase the comfort of the footwear article.

[0004] Traditionally, the sole is secured to the upper using a construction known as Strobel construction, in which the different sole elements (specifically the insole, midsole and outsole) are assembled together. The method of manufacturing traditional shoes requires dozens of steps and generates a lot of waste from the cut materials.

[0005] It is desirable to simplify the manufacturing method of an article of footwear, in particular by reducing the number of steps and / or the consumption of energy and materials. This problem is also part of the search for a manufacturing method that can be carried out as close as possible to the point of use of the article of footwear in order to reduce carbon emissions, facilitate inventory management, and allow personalization of the article of footwear.

[0006] One solution is to eliminate the sewing step required to give a three-dimensional shape to an initially flat upper. The upper is assembled from one or more parts, rather than from multiple parts attached together by sewing.

[0007] Thus, known articles of footwear include a textile tubular element including a hot melt textile portion that at least partially forms an upper. It would therefore be desirable to improve these articles of footwear so that they are light, soft, breathable, while providing satisfactory wear and tear resistance and comfortably fitting the shape of the foot.

[0008] FR 3 098 690 A1 describes the manufacture of a shoe with two superimposed textile tubular elements, said textile tubular elements comprising at least partially heat-fusible yarns which are heat-fused during the heat-fusion of the two textile tubular elements into an upper. FR 3 098 690 A1 describes that different stitching patterns and different types of yarns (plain and / or colored and / or transparent, see

[0126] ) can be used, but does not specify the type of yarn or its arrangement in the shoe.

[0009] Such articles of footwear, while having a specific construction, must also provide a variety of designs that meet the above-mentioned technical standards while limiting the aesthetic and / or functional components required to manufacture them.

[0010] Therefore, it may be desirable that a specific portion of the footwear article forms one or more visualization areas when viewed from the outside thereof. Therefore, it is suggested to melt the heat-fusible yarn and form a transparent film-forming area. However, when the heat-fusible monofilament yarn has a large diameter, such a film-forming area may reduce the air permeability and softness of the upper; or when the heat-fusible monofilament yarn has a small diameter, such a film-forming area may reduce the wear resistance / tear resistance of the upper. In addition, when the upper includes an inner layer and an outer layer with heat-fusible yarns, these heat-fusible yarns may adhere to the inner layer when heat-melting, thereby further stiffening the treated area of ​​the upper.

[0011] Therefore, it is desirable to form a visualization area that does not change the air permeability, or at least limit the reduction in air permeability, and maintain good softness, as well as good wear resistance and tear resistance in the upper area including the visualization area, especially when through holes are set in the visualization area.

[0115] definition

[0116] In the present context, the term "heat-fusible" or "first heat-fusible component" should be understood to mean any material or first component which is heat-fusible during the manufacturing process of the shoe according to the invention.

[0117] In this document, the term "foot insertion opening of a shoe, sock (inside or outside) or textile tubular element (inside or outside)" should be understood to mean a natural opening for inserting the foot into the foot-accommodating volume of a shoe, sock or textile tubular element, specifically arranged between the midfoot region and the hindfoot region, more particularly around all or part of the ankle.

[0118] In this context, the term "non-heat-fusible" should be understood to mean any material / component that is not heat-fusible during the manufacturing process of the footwear according to the invention. Such a material or component may be a thermoplastic or non-thermoplastic material, but its melting or softening temperature or degradation temperature is higher than the highest heating temperature involved in the manufacturing process of the footwear according to the invention.

[0119] In the present context, the term "transparent and / or translucent" is understood to mean any material (in particular any monofilament) through which one or more colors, and / or one or more patterns (optionally in relief) can be seen.

[0120] For example, by varying the mass percentage of titanium dioxide in the monofilament yarn, the transparency of the yarn can be varied until it is translucent.

[0121] In the present context, the term "at least partially heat-fusible yarn" is understood to mean that the yarn is completely heat-fusible or that each yarn including a part of its structure is heat-fusible.

[0122] In a variant embodiment, the main inner textile portion comprises one or more transparent and / or translucent monofilament yarns, in particular forming an inner visualization zone.

[0123] In a variant embodiment, the inner textile tubular element (in particular the foot at least partially covering the inner textile component) comprises:

[0124] - one or more heat-fusible textile parts which are at least partially heat-fusible during the manufacture of the shoe, in particular one or more at least partially heat-fusible yarns; and / or

[0125] - one or more multifilament yarns and / or one or more yarns spun from fibers, in particular not heat-fusible, more particularly made from polyester and / or regenerated fibers, for example from PET (polyethylene terephthalate) or PBT (polybutylene terephthalate); and / or

[0126] - one or more elastic yarns, in particular made of elastane; and / or

[0127] - One or more transparent and / or translucent monofilament yarns, in particular not heat-fusible, are arranged in a main inner textile part or in an additional inner textile part, at least partially overlapping a main outer textile part or in an additional outer textile part of the outer textile tubular element.

[0128] In a variant embodiment, the outer textile tubular element (in particular the foot at least partially covering the outer textile component) comprises:

[0129] - one or more heat-fusible textile parts which are at least partially heat-fusible during the manufacture of the shoe, in particular one or more at least partially heat-fusible yarns; and / or

[0130] - one or more non-thermofusible multifilament yarns and / or one or more, in particular non-thermofusible, spun yarns, more particularly made of polyester and / or regenerated fibers, for example PET (polyethylene terephthalate) or PBT (polybutylene terephthalate); and / or

[0131] - one or more elastic yarns, in particular made of elastane; and / or

[0132] - One or more transparent and / or translucent monofilament yarns, in particular not heat-fusible, are arranged in a main outer textile part or in an additional outer textile part, at least partially overlapping a main inner textile part or in an additional inner textile part of the inner textile tubular element.

[0133] In a variant embodiment, the inner textile tubular element and / or the outer textile tubular element each comprise one or more elastic yarns in a zone surrounding all or part of the foot insertion opening; in particular said zone does not comprise any hot-melt textile portion.

[0134] In one embodiment, an inner textile tubular element or an outer textile tubular element, in particular an at least partially ground-covering inner textile component or an outer textile component, comprises one or more lace buckles in its forefoot area (the forefoot area extending between the medial side and the lateral side) and / or instep area, which lace buckles are integrally formed with the inner textile tubular element or the outer textile tubular element, in particular with the at least partially ground-covering inner textile component or the outer textile component.

[0135] Advantageously, when the lace buckle is arranged on the internal textile tubular element, the external textile tubular element comprises one or more receiving through-holes in its forefoot area (which extends between the medial side and the lateral side) and / or instep area, and the receiving through-holes are configured to allow the lace buckle to pass through the one or more receiving through-holes so as to protrude out of the one or more receiving through-holes, respectively.

[0136] In one embodiment, the lace lock is defined by two through holes, in particular a one-piece textile (in particular knitted) construction with the inner textile tubular element or the outer textile tubular element. The two through holes are preferably arranged in the forefoot area extending between the lateral side and the medial side and / or in the instep area.

[0137] For example, a shoelace lock is a knitted bridge.

[0138] In particular, the instep region and / or the forefoot region extending between the lateral side and the medial side of the inner textile tubular element or the outer textile tubular element comprises a first and a second group of lacing through holes. Each of the first and the second groups of lacing through holes comprises a plurality of pairs (e.g., three to six pairs) of through holes, each pair comprising two through holes, the two through holes of each pair being separated by a knitted portion forming a first bridge or a second bridge. More particularly, the first bridge and the second bridge of the first and the second group of through holes, respectively, are arranged along a transverse direction T that is substantially perpendicular to the longitudinal axis L of the inner textile tubular element and the outer textile tubular element.

[0139] In one embodiment, the lace lock is formed by a weft-knitted yarn, which protrudes from the outer surface of the outer textile tubular element or the inner textile tubular element, in particular the outer surface of the forefoot area and / or the instep area located between the lateral side and the medial side.

[0140] In a variant embodiment, the transparent and / or translucent monofilament yarn is not heat-fused.

[0141] Advantageously, the areas where the yarns cross each other (in particular the stitches knitted with said yarns) are able to move relative to each other. This arrangement imparts flexibility to the main outer textile part and improves breathability. Thus, the main outer textile part can dissipate heat and / or transpiration.

[0142] In a variant, at least one yarn chosen from the transparent and / or translucent monofilament yarns of the main outer textile portion comprises a thermoplastic elastomer, in particular an olefinic thermoplastic elastomer.

[0143] Knitting monofilament yarns (especially transparent and / or translucent monofilament yarns) on circular knitting machines is difficult because the monofilament yarn must adopt the curvature of the continuous knitting loops and must also adopt the tubular shape of the textile tubular element. If the monofilament yarn is not suitable, it is easy to break on the knitting machine and / or produce a different tautness on the tubular element than the multifilament yarn, resulting in an uneven appearance.

[0144] Furthermore, this monofilament yarn is combined with at least one at least partially heat-fusible yarn in a knitted tubular element which is subjected to a thermoforming or thermocompression step.

[0145] Monofilament yarns that are too hard and / or too thick cannot provide satisfactory results. This is because knitted tubular elements formed by thermoforming or thermocompression with inappropriate monofilament yarns do not have an aesthetically pleasing and uniform surface effect, and can also cause discomfort to the user when wearing.

[0146] Advantageously, the use of a transparent and / or translucent monofilament yarn in the form of a thermoplastic elastomer helps to obtain a uniform textile tubular element, which can undergo a thermoforming or thermocompression step to produce an upper that maintains a uniform appearance. In addition, such a monofilament yarn can be loosely woven, i.e. without exerting significant tension on the latter, which facilitates the thermocontraction step described below.

[0147] Preferably, the thermoplastic elastomer, in particular of the olefinic type, represents or occupies at least 50% by mass, preferably at least 80% by mass, preferably at least 90% by mass of the total mass of at least one monofilament yarn.

[0148] In the present context, the term "olefinic thermoplastic elastomer" is understood to mean any elastomer comprising olefinic repeating units, in particular based on propylene and / or ethylene.

[0149] The olefinic thermoplastic elastomer may be selected from:

[0150] - polyisobutylene (PIB); and / or

[0151] - ethylene propylene diene monomer (EPDM); ethylene and propylene copolymers; ethylene-α-olefin copolymers, such as ethylene and butene copolymers or ethylene and octene copolymers, and mixtures of these; preferably EPDM with ethylene and propylene copolymers; and / or

[0152] - mixtures of polyolefins, in particular polypropylene, with one or more unvulcanized olefinic thermoplastic elastomers and optionally one or more plasticizers, such as mineral oil, naphthenic oil or paraffin oil; and / or

[0153] - The olefinic thermoplastic elastomer may be an ethylene and propylene copolymer, an ethylene-propylene-diene terpolymer, an ethylene-α-olefin copolymer (eg, an ethylene and butene copolymer or an ethylene and octene copolymer).

[0154] The at least one transparent and / or translucent monofilament yarn may include one or more thermoplastic elastomers.

[0155] In one embodiment, at least 80% (by mass), preferably about 100% (by mass) of the main outer textile part is formed by one or more monofilament yarns, (each) monofilament yarn comprising one or more thermoplastic elastomers, in particular one or more olefinic thermoplastic elastomers.

[0156] Advantageously, such a diameter spacing makes it possible to knit said monofilament yarns on a circular knitting machine and obtain a uniform upper.

[0157] In one sub-variant, at least one yarn selected from the transparent and / or translucent monofilament yarns of the main outer textile part has at least one of the following properties:

[0158] - has a linear mass density in the range of about 50 dtex to about 300 dtex, preferably in the range of about 50 dtex to about 200 dtex, more preferably in the range of about 100 dtex to about 200 dtex; and / or

[0159] - has a diameter greater than or equal to 0.05 mm and less than or equal to 0.8 mm, preferably greater than or equal to 0.08 mm and less than or equal to 0.3 mm; and / or

[0160] - comprises one or more thermoplastic elastomers, in particular olefins; and / or

[0161] - has a tenacity (cN / tex, centinewton / tex) greater than or equal to 10 cN / tex, in particular less than or equal to 100 cN / tex, more particularly less than or equal to 50 cN / tex; and / or

[0162] - having an elongation at break greater than or equal to 40%, in particular greater than or equal to 60%, more particularly less than or equal to 100%.

[0163] Elongation at break and tenacity can be measured using ISO 2062:2009, entitled "Textiles - Yarns from packages - Determination of single-end breaking force and elongation at break using constant rate of extension (CRE) tester", for example, the elongation can be 100 mm / min.

[0164] In a variant embodiment, the main external textile portion and optionally the main internal textile portion are arranged in at least one of the following areas of the upper: a forefoot area extending on the lateral side and / or a forefoot area extending on the medial side; an instep area; a forefoot area extending between the lateral side and the medial side; a midfoot area extending on the lateral side and / or a midfoot area extending on the medial side; a heel area extending on the lateral side and / or a heel area extending on the medial side; a heel area extending between the medial side and the lateral side; or a combination thereof, preferably a forefoot area extending on the lateral side and / or a forefoot area extending on the medial side; and / or an instep area; and / or a forefoot area extending between the lateral side and the medial side; a midfoot area extending on the lateral side and / or a midfoot area extending on the medial side.

[0165] Advantageously, the main outer textile portion occupies at least 10%, preferably at least 20%, 30%, 40%, 50%, 60%, 70% or 80% of the outer surface of the upper or at least part of the foot of the outer textile tubular element covering the outer surface of the textile component.

[0166] In a variant embodiment, the main inner textile portion is arranged in at least one of the following areas of the upper: a forefoot area extending on the lateral side and / or a forefoot area extending on the medial side; a forefoot area extending between the lateral side and the medial side; an instep area; a midfoot area extending on the lateral side and / or a midfoot area extending on the medial side; a heel area extending on the lateral side; and / or a heel area extending on the medial side; a heel area extending between the medial side and the lateral side; or a combination thereof, preferably a forefoot area extending on the lateral side and / or a forefoot area extending on the medial side; and / or an instep area; and / or a forefoot area extending between the lateral side and the medial side; a midfoot area extending on the lateral side and / or a midfoot area extending on the medial side.

[0167] Advantageously, the main inner textile portion occupies at least 10%, preferably at least 20%, 30%, 40%, 50%, 60%, 70% or 80% of the outer surface of the upper or the foot-covering textile component of the inner textile tubular element.

[0168] In a variant embodiment, the outer textile tubular element is a knitted sock including a foot receiving void, and the inner textile tubular element is a knitted sock at least partially disposed in the foot receiving void of the outer textile tubular element.

[0169] Advantageously, the knitted sock of the inner textile tubular element or the outer textile tubular element comprises a heel region, a toe tip (in particular closed by a seam or weld) and an opening for the insertion of the foot.

[0170] Advantageously, the inner textile tubular element and the outer textile tubular element are at least partially superimposed.

[0171] In one embodiment, the inner textile tubular element and the outer textile tubular element are two different knitted pieces.

[0172] This arrangement facilitates differentiation between inner (or outer) textile tubular elements and outer (or inner) textile tubular elements, particularly in terms of size and / or construction (eg, the arrangement of an additional knitted pocket of an integral knitted construction with a knitted textile tubular element).

[0173] In a variant embodiment, the outer textile tubular element and the inner textile tubular element are of one-piece textile construction.

[0174] Advantageously, the inner textile tubular element and the outer textile tubular element are made of a single textile piece, in particular of a one-piece textile construction, more particularly of a one-piece knitted construction.

[0175] Preferably, prior to folding the inner textile tubular element into the foot receiving volume of the outer textile tubular element, in particular in the shoe manufacturing method according to the second aspect of the invention, the textile piece is substantially U-shaped.

[0176] Preferably, the inner sock is located in a folded position within the foot receiving volume of the outer sock.

[0177] The folding of the inner sock begins at the level of the foot insertion opening or at the level of the open toe.

[0178] In a variant embodiment, the foot insertion opening or the toe tip of the outer textile tubular element is in a textile connection, in particular a knitted connection, with the foot insertion opening or the toe tip of the inner textile tubular element, respectively.

[0179] Thus, during the manufacturing method, folding is initiated from the foot insertion opening, or from the open toe.

[0180] In a variant embodiment, the main inner textile portion does not include any hot-melt textile portion.

[0181] Advantageously, a peripheral area of ​​the upper, which adjoins all or part of the at least partially superimposed main inner textile portion and outer textile portion, comprises one or more hot-melt textile portions, in particular fixing the foot-covering inner textile component with the foot-covering outer textile component.

[0182] In a variant embodiment, the main inner textile portion comprises one or more non-thermofusible monofilament yarns, optionally transparent and / or translucent.

[0183] Preferably, the one or more yarns form an inner visualization area which substantially faces a visualization area of ​​the main outer textile part (which may be referred to as outer visualization area).

[0184] Advantageously, the interior visualization area enables visualization of the interior of the receiving volume of the shoe and thus also of the part of the foot facing said area.

[0185] In a variant embodiment, the inner textile tubular element (particularly its foot at least partially covers the inner textile component) includes one or more hot-melt textile parts, while the outer textile tubular element (particularly its foot covers the outer textile component) does not include any hot-melt textile parts or includes one or more hot-melt textile parts whose total mass is less than or equal to 0.50 times the total mass of the hot-melt textile parts of the inner textile tubular element, and particularly less than or equal to 0.50 times the total mass of the (one or more) hot-melt textile parts of the foot covering the inner textile component.

[0186] Advantageously, the outer textile tubular element comprises less hot-melt textile material than the inner textile tubular element.

[0187] This arrangement makes the outer tubular member more flexible and breathable than the inner tubular member.

[0188] In a variant embodiment, the main external textile part or the additional external textile part, and / or the main internal textile part or the additional internal textile part both comprise one or more textile through-holes, in particular knitted, more particularly knitted with one or more monofilament yarns (as described herein, for example, transparent and / or translucent) or one or more multifilament yarns.

[0189] Preferably, the through-holes extend between the inner surface and the outer surface of the main outer textile part or the additional outer textile part and / or the main inner textile part or the additional inner textile part.

[0190] The main outer textile part or the additional outer textile part or the main inner textile part or the additional inner textile part may comprise through holes:

[0191] - distributed over a given area of ​​the main portion or the additional portion, for example covering a given forefoot area of ​​the textile component, and / or

[0192] - around at least a portion of the main portion or of the additional portion in a given area, for example in the midfoot area on the lateral or medial side of the covering textile component, and / or

[0193] - Areas of the upper that are less subject to tensile or shear stress.

[0194] The through hole includes (or is) one or more through holes, in particular at least 3, 4, 5 or more than 5 through holes, at least one dimension of (each) through hole is greater than or equal to 1mm, 2mm, 3mm, 4mm, 5mm or 8mm, or greater than or equal to 10mm, in particular the through hole is defined as one or more through holes A.

[0195] The through hole includes (or is) one or more through holes, in particular at least 3, 4, 5 or more than 5 through holes, at least one dimension of (each) through hole is less than or equal to 20mm, 15mm, 8mm, 5mm, 4mm, 3mm, 2mm or 1mm, in particular the through hole is defined as one or more through holes A.

[0196] In a preferred example, the through hole includes (or is) one or more through holes, at least one dimension of the through hole is between 3 mm and 15 mm, preferably between 5 mm and 15 mm, in particular type A.

[0197] The one or more through holes may have any shape, such as an oval, circular, parallelogram (eg, square or rectangular) shape.

[0198] The through holes include one or more through holes, in particular at least 3, 4, 5, more than 5 or more than 30 through holes, at least one dimension of (each) through hole is greater than or equal to 0.1 mm or 0.5 mm, and less than or equal to 1 mm or 2 mm, in particular the through holes are defined as one or more through holes B. For example, this type of through hole B is located on the main inner textile part or the additional inner textile part or the main outer textile part or the additional outer textile part of the knitted mesh or honeycomb structure.

[0199] In a preferred example, the through hole comprises (or is) one or more through holes, at least one dimension of which ranges from 0.1 mm to 2 mm, preferably from about 0.8 mm to 2 mm, in particular of type B.

[0200] Advantageously, the through holes (particularly of type A and / or type B) are knitted with one or more transparent and / or translucent monofilament yarns (particularly not heat-fusible) or one or more multifilament yarns (particularly not heat-fusible).

[0201] This arrangement can form a tear-resistant through hole.

[0202] This arrangement also increases the softness and breathability of the main outer textile portion or the additional outer textile portion or the main inner textile portion or the additional inner textile portion, and improves its display / visualization function.

[0203] In a first exemplary embodiment, the main outer textile part or the additional outer textile part does not comprise any through-holes, whereas the main inner textile part or the additional inner textile part comprises one or more through-holes, in particular of type A and / or type B, more in particular of type B.

[0204] Advantageously, the one or more through holes of the main inner textile part or of the additional inner textile part are knitted with one or more multifilament yarns.

[0205] In a second exemplary embodiment, the main inner textile part or the additional inner textile part comprises one or more textile through-holes, in particular knitted, in particular knitted with one or more monofilament yarns (as described herein, for example, transparent and / or translucent) or one or more multifilament yarns.

[0206] The arrangement of the aforementioned first and second embodiments can advantageously improve the tear resistance of the upper, because one or more through holes arranged in the inner textile tubular element are covered by the outer textile tubular element, in particular, the inner textile tubular element does not include any through holes.

[0207] In a second exemplary embodiment, the main inner textile part or the additional inner textile part does not comprise any through-holes, whereas the main outer textile part or the additional outer textile part comprises one or more through-holes, in particular of type A and / or type B, in particular of type A.

[0208] In a third exemplary embodiment, the main internal textile part or the additional internal textile part comprises one or more through holes, the main external textile part or the additional external textile part comprises one or more through holes, at least one dimension of each through hole is larger than at least one dimension of each through hole of the main internal textile part or the additional internal textile part, in particular the main external textile part or the additional external textile part comprises one or more through holes A, and the main internal textile part or the additional internal textile part comprises one or more through holes B.

[0209] In a variant embodiment, the main outer textile part or the additional outer textile part comprises one or more through holes which do not face the one or more through holes of the main inner textile part or the additional inner textile part.

[0210] Such an arrangement can protect the foot located in the receiving volume of the shoe from, for example, rain, dust, particles, etc.

[0211] In a variant embodiment, the main inner textile portion and the main outer textile portion are at least partially (in particular entirely) arranged in a midfoot area extending on the outer side of the upper, the inner textile tubular element further includes an additional inner textile portion, the outer textile tubular element includes an additional outer textile portion, the additional inner textile portion and the additional outer textile portion are at least partially overlapped and at least partially (in particular entirely) arranged in the midfoot area on the inner side of the upper, and the additional outer textile portion includes one or more transparent and / or translucent monofilament yarns (in particular not heat-meltable) to form a visualization area of ​​the additional inner textile portion.

[0212] In a sub-variant embodiment, the upper further includes another additional inner textile portion and another additional outer textile portion, which are at least partially overlapped and at least partially (in particular completely) arranged in the forefoot area between the lateral side and the medial side, and optionally arranged in the forefoot area located on the lateral side and / or in the forefoot area located on the medial side.

[0213] In a variant embodiment, the main external textile part or the additional external textile part includes an inner surface part, and the main internal textile part or the additional internal textile part includes an outer surface part, which is not fixed to the inner surface part of the main external textile part or the additional external textile part, in particular not bonded by a hot melt textile part.

[0214] In a variant embodiment, the main outer textile portion or the additional outer textile portion comprises one or more translucent and / or transparent monofilament yarns, each yarn having a trilobal cross-section and preferably having a linear mass density greater than or equal to 20 denier and less than or equal to 60 denier.

[0215] The inventors have established that such an arrangement enables the use of the monofilament yarn on a textile machine, in particular by knitting, while providing a good compromise between hardness and softness.

[0216] Additionally, this yarn provides lustre.

[0217] In the present context, the term "trilobal cross section" is understood to mean that the cross section of the monofilament yarn comprises at least three sides.

[0218] Advantageously, the trilobal cross-section has a substantially triangular overall shape.

[0219] According to a second aspect, the subject of the invention is a method for manufacturing a shoe, in particular a sports shoe, in particular according to any variant embodiment of the first aspect of the invention, the method advantageously comprising the following steps:

[0220] i) providing an outer textile tubular element and an inner textile tubular element, wherein at least one of the inner textile tubular element and the outer textile tubular element comprises at least one heat-fusible textile portion, the outer textile tubular element comprises at least one main outer textile portion, the inner textile tubular element comprises at least one main inner textile portion, the inner textile tubular element is at least partially arranged in a foot receiving void of the outer textile tubular element, such that the outer textile tubular element and the inner textile tubular element at least partially overlap, and such that the main inner textile portion and the main outer textile portion at least partially overlap, the main outer textile portion comprising one or more transparent and / or translucent monofilament yarns, the monofilament yarns in particular having a melting temperature Tf or a degradation temperature Td;

[0221] ii) heating the inner textile tubular element and the outer textile tubular element to a heating temperature Tc in order to at least partially melt the at least one heat-fusible textile portion, in particular the temperature Tf or Td being greater than the heating temperature Tc;

[0222] iii) obtaining an upper comprising at least a portion of an external textile tubular element and at least a portion of an internal textile tubular element, at least one of the internal textile tubular element and the external textile tubular element comprising at least one hot-melt textile portion, the at least one main external textile portion forming a visualization area of ​​the main internal textile portion.

[0223] In one example, the method comprises the step of fixing the sole structure to the sole external textile part of the external textile tubular element or to the upper obtained in step iii).

[0224] In one example, the method includes a thermoforming or thermocompression step, in which one or more sole elements can be arranged between an inner textile component of the sole of an inner textile tubular element and an outer textile component of the sole of an outer textile tubular element, or in contact with a sole textile component of an outer textile tubular element, in particular for fixing by bonding, more particularly by bonding one or more hot-melt textile parts.

[0225] The thermoforming step, in particular the heating step ii), advantageously comprises thermoforming at least part of the foot of the inner and outer textile tubular elements covering the inner and outer textile parts into the shape of a preform which is in the general shape of the foot. The inner and outer textile tubular elements are held under pressure against the preform during their cooling to follow and maintain the shape of the preform. The at least partly heat-fusible yarns can be bonded to each other.

[0226] A preform in the general shape of a foot is preferably arranged in the foot-receiving volume of an inner textile tubular element, the textile tubular elements at least partially overlapping.

[0227] The thermocompression step, in particular the heating step (ii), advantageously comprises arranging the inner textile tubular element and the outer textile tubular element with one or more sole elements in a mould. Preferably, an inflatable (inflatable) bladder (particularly made of silicone) is arranged in the foot-accommodating volume of the inner textile tubular element, which is substantially foot-shaped, and the inner textile tubular element is at least partially superimposed with the outer textile tubular element. During the thermocompression process, the inflatable bladder is inflated, for example, to an inflation pressure ranging from about 3 bar to about 6 bar, so that the inner textile tubular element and the outer textile tubular element and the optional sole element are pressed against the inner surface of the mould. The mould may be made of two parts or three parts. For example, two mould parts are configured to receive and mould the upper, and one mould part is configured to receive and mould the sole structure. The heating temperature during the thermocompression process is determined so that the target hot-melt textile material melts and spreads.

[0228] Specifically, the shoe may include one or more textile materials that are heat-fusible in nature, but are not heat-fused during the process of manufacturing the shoe. Therefore, according to the present invention, such textile materials are considered to be non-heat-fusible or non-heat-fusible materials.

[0229] For example, the heating temperature is higher than or equal to 110°C and lower than or equal to 200°C, and particularly in the range of 110°C to 160°C.

[0230] The inner textile tubular element or the outer textile tubular element can be knitted on a small diameter circular knitting machine. The knitted fabric can be weft knitted or warp knitted, preferably weft knitted.

[0231] After step (iii), the method may comprise the step of fixing one or more sole elements to the sole outer textile part of the outer textile tubular element, for example by gluing a rubber portion.

[0232] Metal spikes may then also be screwed into protrusions protruding from the outer surface of the sole outer textile part of the outer textile tubular element to form cleats.

[0233] The sole element may be arranged between the inner and outer sole textile parts of the inner and outer textile tubular elements, respectively, the sole element being an outsole or an absorption element, for example having a Shore A hardness greater than 30 and less than 80.

[0234] In a variant, at least the outer textile tubular element, and in particular the outer textile tubular element and the inner textile tubular element, undergo a heat shrinking step before step ii).

[0235] In a variant, at least one yarn selected from the transparent and / or translucent monofilament yarns of the main outer textile portion comprises one or more thermoplastic elastomers, in particular one or more olefinic thermoplastic elastomers.

[0236] In a variant, at least one yarn selected from the transparent and / or translucent monofilament yarns of the main outer textile part is selected to have a thermal shrinkage greater than or equal to 5%, preferably greater than or equal to 7%, however preferably less than or equal to 20%, more preferably less than or equal to 15%.

[0237] This arrangement enables heat shrinkage of the monofilament yarn in the heat shrinking step to take place prior to the thermoforming or thermocompression step ii).

[0238] Advantageously, the main outer textile part, and optionally one or more other parts of the outer textile tubular element and / or the inner textile tubular element, are knitted from one or more transparent and / or translucent monofilament yarns, to which low tension is applied during knitting, i.e. "loose". Furthermore, said transparent and / or translucent monofilament yarns have a significant (dimensional) shrinkage.

[0239] Advantageously, before the thermoforming and / or thermocompression step ii), a heat shrinking step can activate the dimensional shrinkage (%) of the transparent and / or translucent monofilament yarn, thereby obtaining a main external textile part according to the arrangement of the transparent and / or translucent monofilament yarn, and optionally generally an external textile tubular element and / or an internal textile tubular element, which has a uniform knitted surface and the shape is adjusted according to the preform.

[0240] Advantageously, the heat shrinking step comprises heating at least the outer textile tubular element for a determined period of time to obtain the desired dimensional shrinkage of the outer textile tubular element and optionally the inner textile tubular element, for example comprising the use of hot water (e.g. 80° C.) or steam for at least 5 seconds, for example 30 seconds to 5 minutes.

[0241] The shrinkage rate (%) of at least one yarn of the external textile tubular element and / or the internal textile tubular element is evaluated by the following calculation: [(the length of area A arranged in the internal / main external textile part taken along the weft direction or the stitch direction before the heat shrinking step; or the so-called initial length) - (the length of the area A arranged in the main external / inner textile part taken along the selected weft direction or the stitch direction after the heat shrinking step; or the said activated length)] / (initial length) * 100.

[0242] Advantageously, the shrinkage measured on the transparent and / or translucent monofilament yarn is greater than or equal to 5%.

[0243] Advantageously, the shrinkage measured over area A of said external textile tubular element is greater than or equal to 5%.

[0244] Definitions, variations, examples and embodiments according to the first aspect of the present invention can be applied to the second aspect of the present invention independently of each other. BRIEF DESCRIPTION OF THE DRAWINGS

[0264] The shoe 10 further comprises a longitudinal axis L and a transverse axis T, in particular substantially perpendicular to the axis L. The shoe 10 further comprises a front edge 19a and a rear edge 19b. The article of footwear 10 comprises an upper 15 and a sole structure 20, in particular an outsole.

[0265] In addition to being applicable to the shoe 10, the forefoot area 12, the midfoot area 14, the heel area 16, the lateral side 17, the medial side 18, the front edge 19a, the rear edge 19b, the instep area 11, the foot insertion opening 5 and the foot accommodating or receiving volume 6 may also be applicable to the sole structure 20, the upper 15 and its individual elements, such as but not limited to the inner textile tubular elements and the outer textile tubular elements and their respective textile foot covering parts and their respective textile sole parts.

[0266] For reference purposes, Figure 2 The different areas and Figure 1 corresponds to the area defined in .

[0267] Figure 3 Schematically illustrated is a first example of an inner textile tubular element 50 and a first example of an outer textile tubular element 60, which are different from each other but are both made of knitted textile pieces, in particular, knitted socks. The inner textile tubular element 50 comprises a foot-covering inner textile component 52 and a sole inner textile component 54, as well as a curved portion 56 capable of forming a heel region. In this specific example, the foot-covering inner textile component 52 extends in the forefoot region, the midfoot region and the heel region, and extends from the outside to the inside. In this specific example, the sole inner textile component 54 extends between the front edge and the rear edge in the forefoot region, the midfoot region and the heel region, and extends from the outside to the inside.

[0268] The outer textile tubular element 60 includes a foot covering outer textile component 62 and a sole outer textile component 64, and a curved portion 66 that can form a heel region. In this specific example, the foot covering outer textile component 62 extends in the forefoot region, the midfoot region, and the heel region, and extends between the lateral side and the medial side. In this specific example, the sole outer textile component 64 extends between the front edge and the rear edge and between the lateral side and the medial side in the forefoot region, the midfoot region, and the heel region.

[0269] The inner textile tubular element 50 is arranged in the receiving volume 61 of the outer textile tubular element 60, so that they are substantially at least partially superimposed. The inner textile tubular element 50 and the outer textile tubular element 60 are preferably placed on a foot-shaped preform (in particular, the preform is arranged in the foot receiving volume of the inner textile tubular element 50), and then undergo a thermoforming or thermocompression step, in which the heat-fusible textile parts of the inner textile tubular element 50 and the outer textile tubular element 60 are heat-fused so as to fix the inner textile tubular element 50 to the outer textile tubular element 60 and form the shape of the foot-shaped preform together. Then, the inner textile tubular element 50 and the outer textile tubular element 60 are cooled on the preform, preferably in order to fix the shape.

[0270] During the thermoforming step, the preform is preferably stiff.

[0271] During the thermocompression step, the preform is an inflatable bag (particularly made of silicone or polyurethane material, capable of inflate and deflate, and therefore reusable). The heating temperature applied during the thermocompression step is determined to almost completely melt the one or more heat-fusible materials in question. Thus, depending on the desired effect, the yarns can be bonded together and / or the yarns can form a film or coating, for example coating the inner textile tubular element 50 or the outer textile tubular element 60.

[0272] One or more sole elements, such as an outsole or a flexible sole element made of a material having a Shore A hardness between 40 and 70, are arranged between the inner sole textile component 54 and the outer sole textile component 64 .

[0273] Preferably, the inner sole textile component 54 and the outer sole textile component 64 are substantially composed of heat-fusible yarns, or each includes at least 80% heat-fusible yarns by mass accounting for the total mass. Preferably, in the thermal compression step, at least part of the heat-fusible yarns or all of the heat-fusible yarns of the inner sole textile component 54 and the outer sole textile component 64 are heat-fused.

[0274] Since the inner textile tubular element 50 and the outer textile tubular element 60 are preferably different knitted pieces, they can have different configurations. Figure 3 As shown, the foot-covering outer textile component 62 covers the foot less than the foot-covering inner textile component 52 , in particular the foot-covering outer textile component 62 does not include any instep and covers the ankle less than the foot-covering inner textile component 52 .

[0275] Figure 4 A second example of an inner textile tubular element 70 and a second example of an outer textile tubular element 80 are schematically shown, which have a one-piece textile construction, in particular made into a single U-shaped knitted piece. In this specific example, the inner textile tubular element 70 and the outer textile tubular element 80 are knitted together at the level of the foot insertion opening corresponding to the fold line 75, from which the inner textile tubular element 70 is inserted into the foot receiving volume 85 of the outer textile tubular element 80. The inner textile tubular element 70 and the outer textile tubular element 80 are advantageously knitted socks and each have a curved portion 72, 82.

[0276] The inner textile tubular element 70 and the outer textile tubular element 80 are arranged on a foot-shaped preform (not shown); specifically, the preform is arranged in the foot-accommodating volume of the inner textile tubular element 70. Then, the inner textile tubular element 70 and the outer textile tubular element 80 undergo a thermoforming or thermocompression step, in which the heat-fusible textile portion is heat-fused to fix the inner textile tubular element 70 and the outer textile tubular element 80 to each other and to form them into the shape of the preform.

[0277] exist Figures 3 to 5 In the embodiment of the present invention, the inner sole textile component 54 or 72 and the outer sole textile component 64 or 82 are shown as being configured to be completely placed under the foot. In another example, depending on the configuration of the selected sole structure, the inner sole textile component 54 or 72 and / or the outer sole textile component 64 or 82 wrap a portion of the instep and along all or part of the circumference of the foot. The heat compression step can be performed with reference to the description of the first inner textile tubular element 50 and the outer textile tubular element 60.

[0278] Below Figures 6 to 12 Mainly different examples of constructions of inner and outer textile tubular elements according to the invention are described, in particular different constructions of superimposed main inner and outer textile portions.

[0279] Figure 6 Schematically illustrated is a shoe 100 comprising an upper 110 and a sole 120. The shoe 100 comprises an inner textile tubular element 130, which is at least partially arranged in a foot receiving volume of an outer textile tubular element 140. The upper 110 comprises a foot covering inner textile component 132 of the inner textile tubular element 130 and a foot covering outer textile component 142 of the outer textile tubular element 140.

[0280] Advantageously, the foot covering outer textile component 142 comprises a main outer textile portion 144, which extends partially into the forefoot region between the medial and lateral sides and into the forefoot region on the lateral side and on the medial side, and partially into the midfoot region on the medial and lateral sides. In particular, the main outer textile portion 144 does not extend into the instep region 102. Advantageously, the main outer textile portion 144 occupies at least 50%, preferably at least 80%, of the total surface occupied by the forefoot region and the midfoot region of the foot covering outer textile component 142. The main outer textile portion 144 comprises a transparent monofilament yarn, in particular, substantially consisting of a transparent monofilament yarn, to form a substantially continuous visualization area extending in the above-mentioned region. The monofilament yarn is a transparent monofilament yarn made of polyethylene terephthalate in a non-limiting example, and its diameter is approximately 0.50 mm.

[0281] Advantageously, the main outer textile portion 144 comprises through holes 146 , in particular through holes A as defined above, more particularly each through hole having at least one dimension da greater than or equal to 2 or 3 mm. Said through holes 146 are preferably knitted simultaneously with the outer textile tubular element 140 .

[0282] Advantageously, the foot-covering inner textile component 132 comprises a main inner textile portion 134, which partially overlaps the main outer textile portion 144. In the present example, the main inner textile portion 134 does not include any through holes. Advantageously, the foot-covering inner textile component 132 comprises a main inner textile portion 134, which at least partially extends in a forefoot region arranged between the lateral side and the medial side and on the lateral side and on the medial side, and in a midfoot region arranged on the lateral side and on the medial side. The foot-covering inner textile component 132 also extends in the instep region 102. Thus, the instep region 102 of the foot-covering inner textile component 132 forms a part of the outer surface of the upper 110. Advantageously, the main inner textile portion 134 occupies at least 50%, preferably at least 80%, of the total surface of the foot-covering inner textile component 132 occupied by the forefoot and midfoot regions arranged on the lateral side and the medial side and the forefoot region arranged between the lateral side and the medial side. The main inner textile part 134, in particular its outer surface 134b, can be seen from the outer surface 144b of the main outer textile part 144. In particular, the textile color (here gray) and texture appearance of the main inner textile part 134 can be seen from the visualization area formed by the main outer textile part 144.

[0283] Figure 7 A third example of an inner textile tubular element 200 is schematically illustrated, partially disposed within a foot-receiving volume of a third example of an outer textile tubular element 250 .

[0284] The outer textile tubular element 250 includes a foot-covering outer textile component 260 including a main outer textile portion 270 consisting essentially of a transparent monofilament yarn and extending at least partially in the forefoot and midfoot regions on the lateral and medial sides of the foot-covering outer textile component 260 and in the forefoot region between the lateral and medial sides. The monofilament yarn is, in a non-limiting example, a transparent monofilament yarn made of polyethylene terephthalate, having a diameter of approximately 0.35 mm, and is not intended to be heat-melted.

[0285] The inner textile tubular element 200 includes a foot-covering inner textile component 210, which includes a main inner textile portion 220, which extends at least partially in the forefoot area and the midfoot area on the lateral and medial sides of the foot-covering inner textile component 210 and in the forefoot area between the lateral and medial sides.

[0286] In this specific example, the main inner textile part 210 includes knitted stitches separated from each other by spaces forming through holes, which are specifically through holes B as described above, and specifically at least one dimension of each through hole is about 1 mm or less. Therefore, the main outer textile part 250 forms a visualization area of ​​the outer surface of the first inner textile part 210. The color, pattern and knit texture of the main inner textile part 210 can be visualized.

[0287] In this particular example, the main outer textile portion 270 does not include any thermofusible yarn, so that the knitted stitches in the latter can move relative to each other and the monofilament yarn can slide through the stitches. Therefore, the main outer textile portion 270 maintains a certain softness and breathability, and can discharge the heat and heat accumulated between the main inner textile portion 210 and the main outer textile portion 270 and in the foot receiving volume.

[0288] In this particular example, main outer textile portion 270 is shown as having a single type of stitching pattern repeated across its entire surface (ie, the yarns are connected to each other). However, main outer textile portion 270 may also include different stitching patterns arranged in different areas.

[0289] In this specific example, the outer textile tubular element 250 includes two pairs 251, 252 of knitted tubes 255, 256, respectively disposed on both sides of the instep area 210. The knitted tube 255 disposed on the outer side of the instep area interacts with the knitted tube 256 disposed on the inner side of the instep area to receive, for example, shoelaces. The knitted tubes 255, 256 are of an integral knitted construction with the outer textile tubular element 250, which is also knitted.

[0290] In this particular example, the outer textile tubular element 260 comprises a single main outer textile portion 270. However, the outer textile tubular element 260 may comprise one or more different additional outer textile portions, in particular, the main outer textile portion and the additional outer textile portions being separated from each other by one or more intermediate outer textile portions which do not comprise any transparent and / or translucent monofilament yarns.

[0291] As a non-limiting example, the foot covering outer textile component 260 includes a knitted heat-fusible textile portion 262 that will melt during the thermocompression step, preferably mixed with a knitted non-heat-fusible textile portion.

[0292] Preferably, the sole inner textile component and the sole outer textile component consist essentially of heat-fusible yarns, which are heat-fused during the thermocompression step.

[0293] In a non-limiting example, the thermofusible yarn is a multifilament yarn made of monocomponent polyurethane, in particular having a linear mass density between 50 and 80 dtex and a number of filaments between 30 and 45.

[0294] Figure 8 A fourth example of an inner textile tubular element 300 is schematically illustrated, which is partially disposed in a foot-accommodating volume of an outer textile tubular element 360, which includes a main outer textile portion 370 consisting essentially of a transparent monofilament yarn and extending partially in the forefoot and midfoot regions on the lateral and medial sides and the forefoot region between the lateral and medial sides of the foot-covering outer textile component 360. In a non-limiting example, the monofilament yarn is a transparent monofilament yarn made of polyethylene terephthalate, has a diameter of approximately 0.35 mm, and is not intended to be heat-meltable.

[0295] The inner textile tubular element 300 includes a foot-covering inner textile component 310, which includes a main inner textile portion 320, which is arranged in the forefoot area and midfoot area located on the lateral and medial sides of the foot-covering inner textile component 320 and in the forefoot area located between the lateral and medial sides.

[0296] In this particular example, the main inner textile portion 310 includes knitted through holes 315, specifically knitted through holes A as described above, more specifically having at least one dimension of about 3-4 mm. Thus, the main outer textile portion 350 forms a visualization area of ​​the outer surface of the main inner textile portion 310. The color, pattern, knitted texture and through holes 315 of the main inner textile portion 310 can all be visualized.

[0297] The through holes 315 of the main inner textile part 310 allow visualization of the accommodation volume of the upper 380 , in particular the part for the foot.

[0298] Fig. 9 A fifth example of an inner textile tubular element 400 is schematically illustrated as being partially disposed in a foot-accommodating volume of a fifth example of an outer textile tubular element 450. The outer textile tubular element 450 includes a foot-covering outer textile component 460 including a main outer textile portion 470 consisting essentially of translucent monofilament yarn and extending partially in a midfoot region on the lateral and medial sides and in a forefoot region between the lateral and medial sides of the foot-covering outer textile component 460.

[0299] The inner textile tubular element 400 includes a foot-covering inner textile component 410 including an inner textile portion 420 that extends partially in a midfoot region on the lateral and medial sides and in a forefoot region between the lateral and medial sides of the foot-covering inner textile component 410 .

[0300] In this particular example, the main inner textile portion 420 includes through holes, specifically knitted through holes, specifically knitted through holes B as described above, and more specifically, the through holes have at least one dimension of about 1 mm or less. Therefore, the main outer textile portion 470 forms a visualization area of ​​the outer surface of the main inner textile portion 420. The color, pattern and knit texture of the main inner textile portion 420 can be visualized.

[0301] In this particular example, the main outer textile portion 470 comprises knitted through-holes 475A as defined above, in particular having at least one dimension of approximately 3 to 5 mm.

[0302] Advantageously, at least one dimension of the through-holes 475 of the main outer textile portion 470 is greater than at least one dimension of each through-hole B of the main inner textile portion 420 .

[0303] In this exemplary embodiment, the knitted through-holes are distributed in a forefoot region disposed between the lateral side and the medial side, and partially adjoin the main outer textile portion 470 in a midfoot region located on the lateral side and the medial side.

[0304] For example, the foot covering outer textile component 460 includes a first group 462 and a second group 463 of through holes 476 to form a lace buckle or textile bridge 477 in the instep area. The lace buckle 476 is defined by two adjacent through holes 476 arranged transversely to the longitudinal axis of the outer textile tubular element 450. The through holes 476 and the outer textile tubular element 450 are of a one-piece textile (particularly knitted) construction.

[0305] exist Fig. 9 , the main external textile portion 470 extends substantially continuously in the forefoot region and the midfoot region. The main external textile portion 470 may alternatively be arranged only in the forefoot region between the lateral side and the medial side, the external textile tubular element 450, in particular its external covering textile component 460, may include a (first) additional external textile portion arranged in the midfoot region located on the lateral side and another (second) additional external textile portion arranged in the midfoot region located on the medial side. In this case, the main external textile portion and the additional external textile portion are different from each other and are optionally separated by one or more intermediate textile portions that do not contain any transparent monofilament yarn. The same alternative arrangement may also be adopted for the internal textile tubular element 410.

[0306] Fig.10 and Fig.11 A sixth example of an inner textile tubular element 500 is schematically illustrated that is partially disposed within a foot-receiving volume of an outer textile tubular element 550. The outer textile tubular element 550 includes a foot-covering outer textile component 560 that includes a main outer textile portion 570 that consists essentially of a transparent monofilament yarn and that extends partially over and between the forefoot, midfoot, and rearfoot regions and on the lateral and medial sides of the foot-covering outer textile component 560.

[0307] The inner textile tubular element 500 includes a foot-covering inner textile component 510 that includes a main inner textile portion 520 that extends partially in the forefoot, midfoot and rearfoot regions of the foot-covering inner textile component 510 and on and between the lateral and medial sides.

[0308] In this particular example, main inner textile part 510 comprises through holes, in particular through holes B as defined above, more particularly having at least one dimension of about 1 mm. Thus, main outer textile part 550 forms a visualization area of ​​the outer surface of main inner textile part 510. The color, pattern and texture (in particular the knitted texture) of main inner textile part 510 can be visualized.

[0309] In this particular example, the main outer textile portion 570 comprises through holes 575 , specifically through holes A as defined above, more specifically having at least one dimension of approximately 3 to 5 mm and at least one dimension greater than at least one dimension of the through holes of the main inner textile portion 510 .

[0310] In this particular example, through-holes 575 are provided in the forefoot, midfoot, and heel regions of the foot-covering outer textile component 560 as well as on and between the lateral and medial sides.

[0311] Preferably, the sole inner textile component 530 and the sole outer textile component 580 are essentially composed of heat-fusible monocomponent multifilament yarns, in particular made of heat-fusible polyurethane. These yarns are therefore heat-fused on the finished shoe.

[0312] Fig.12 A third example of a shoe 700 according to the invention is schematically and partially illustrated, comprising an inner textile tubular element 705 which is partially arranged in a foot-receiving volume of an outer textile tubular element 750 .

[0313] The outer textile tubular element 750 includes a foot-covering outer textile component 760 that includes a main outer textile portion 770 that is essentially composed of transparent monofilament yarn and extends partially to the forefoot and midfoot areas and on and between the lateral and medial sides.

[0314] The inner textile tubular element 705 includes a foot-covering inner textile component 710 that includes a main inner textile portion 720 that is also essentially composed of transparent monofilament yarn and extends partially to the forefoot and midfoot areas and on and between the lateral and medial sides.

[0315] In a non-limiting example, the monofilament yarn is a transparent monofilament yarn made of polyethylene terephthalate, has a diameter of approximately 0.35 mm, and is not intended to be heat-fused.

[0316] In this particular example, the main inner textile portion 720 and the main outer textile portion 770 may each include through holes, specifically through holes B as described above, more specifically having at least one dimension of 1 mm or less, according to the selected stitching pattern.

[0317] The main outer textile portion 770 forms a visualization area for the main inner textile portion 720. The main inner textile portion 720 forms a visualization area for the foot receiving volume. In this configuration, the interior of the shoe can be seen.

[0318] Fig.13 and Fig.14 A fourth example of a shoe 800 according to the invention, in particular a sports shoe, is schematically illustrated, the shoe comprising an outer textile tubular element 850 and an inner textile tubular element 805 folded into a foot receiving volume of the outer textile tubular element 850 .

[0319] In the present example, the outer textile tubular element 850 comprises a foot-covering outer textile component 860, i.e., covering all or part of the top of the foot, and a (non-visible) sole component covering all or part of the sole of the foot. The outer textile tubular element 850 comprises a main outer textile portion 870 knitted with a transparent monofilament yarn; the main outer textile portion 870 extends partly in the forefoot region and the midfoot region arranged on the lateral side (810, 815) and the medial side (820, 825), and partly in the forefoot region arranged between the lateral side and the medial side 830 of the foot-covering outer textile component 860. The transparent monofilament yarn preferably has a diameter of about 0.15 mm and is made of an olefinic thermoplastic elastomer (particularly based on propylene and ethylene) with a shrinkage of about 9% (shrinkage conditions tested: heating at 180° C. for 2 minutes).

[0320] In this example, the inner textile tubular element 805 includes through holes 880 knitted with one or more multifilament yarns, which are arranged in the foot-covering inner textile component 806 (which in particular covers all or part of the foot surface), in the forefoot area and midfoot area on the lateral and medial sides of the foot-covering inner textile component, and partially in the forefoot area between the lateral and medial sides of the foot-covering inner textile component. In particular, at least one dimension of the through holes 880 is greater than or equal to about 10 mm, for example about 10-12 mm. In this specific example, each of the medial and lateral areas has 7 through holes. The through holes, in view of their size, belong to the A type described herein. In this specific example, the forefoot area includes 15 through holes. The textile portion 812 of the inner textile tubular element 805 covered by the main outer textile portion 870 forms the main inner textile portion.

[0321] In the manufacturing process of the upper, the monofilament yarn is loosely knitted. After knitting, the inner textile tubular element 805 is arranged in the foot accommodating volume of the outer textile tubular element 850, and then the inner textile tubular element and the outer textile tubular element (805, 850) stacked in this way are arranged on the preform of the upper shape, and undergo a heat shrinking step, in particular, applying water vapor for about 3 minutes to activate the size shrinkage of the transparent monofilament yarn. Then, the stacked textile tubular element undergoes step ii), so that it is thermoformed into the shape of the preform, thereby realizing that the heat-fusible textile component provided by the heat-fusible yarn at least partially melts or softens. The stacked tubular elements (805, 850) are left on the preform to cool to shape, and then the upper 890 obtained is assembled with the sole assembly 895.

[0322] In this particular example, the inner textile tubular element 805 includes a set of knitted buckle frames 808 disposed in the instep area of ​​the upper 890, and the outer textile tubular element 850 includes a set of through holes 855 disposed in the instep area of ​​the upper 890, through which the buckle frames 808 extend. The frames advantageously form a lacing area for passing the laces.

[0323] Advantageously, the through holes 880 are protected by the outer textile tubular element 850 covering the through holes, in particular by the monofilament, transparent and wear-resistant main outer textile portion 870. Furthermore, these through holes 880 are visible to the user, which contributes to the original appearance.

[0324] Advantageously, the air permeability of the upper of the shoe 800 is improved compared to a similar shoe that does not include any through holes 880 or monofilament yarns. The air permeability of the textile composite composed of the superimposed inner textile tubular elements and the outer textile tubular elements (805, 850) measured in the forefoot region is about 1043.8 l / m 2 / s, while the air permeability of the comparative composite not including any through holes or monofilament yarns is 439.2 m / m 2 / s. Air permeability is determined according to ISO 9237-1995 standard.

[0325] Therefore, the through holes advantageously prevent tearing, significantly improve the breathability of the shoe to discharge heat and hot air, and the through holes can be seen from the outside of the shoe, facilitating understanding of the operation of the shoe.

[0326] Advantageously, the elongation of the upper of the shoe 800 is improved compared to a similar shoe not including through holes 880 or monofilament yarns. The elongation of the textile composite consisting of the superimposed inner and outer textile tubular elements (805, 850) under a force of 15 Newtons is about 17.25 mm, while the elongation of the comparative composite not including any through holes or monofilament yarns is 10.8 mm. The elongation is measured at a temperature of about 20°C + / - 2°C and a relative humidity of 65% + / - 4%, with a test sample length of 150 mm and a width of 50 mm, a tensioner speed of 200 mm / min and a grip width of 100 mm. The measured elongation corresponds to the elongation obtained at the end of two tensioning cycles. The test can be carried out on a tensile test bench suitable for textiles sold by the company Instron.

[0327] Advantageously, even when using monofilament yarns (which are, by definition, stiffer than multifilament yarns), the elongation of the upper according to the invention is advantageously increased by about 60%.

[0328] Fig.15 and Fig.16 A fifth example of a shoe 900 according to the invention, in particular a sports shoe, is schematically illustrated, the shoe comprising an outer textile tubular element 950 and an inner textile tubular element 905, the inner textile tubular element 905 being folded into the foot receiving volume of the outer textile tubular element 950. The shoe 900 is similar to the shoe 800. The shoe 900 differs from the shoe 800 in the lacing system, the ends of the laces being arranged in a buckle frame 910 sewn to a foot-covering outer textile part 960. Furthermore, the main outer textile part 970 of the foot-covering outer textile part 960 has a profile without any notches.

[0329] In an embodiment according to the present invention, and from Figure 7 , Figure 8 and Figures 12 to 16As can be seen from the different variants, the main outer textile part (e.g. 970 or 970) is separated from the outer textile part of the sole of the outer textile tubular element (e.g. 850 or 950) by at least one portion for connecting the outer textile tubular element, which portion does not include any (in particular transparent and / or translucent) monofilament yarn, which portion is, for example, the connecting textile part 862 or 962. In particular, the connecting textile part (e.g. 862 or 962) is partially or substantially entirely adjacent to the lower edge (e.g. 871 or 971) of the main outer textile part (e.g. 870 or 970).

[0330] This arrangement can enhance the connection between the upper and the sole structure.
