Description

Title of the invention: Shoe, in particular sports shoe, and method of manufacturing such a sports shoe Technical field

[0001] The present invention relates to the technical field of footwear articles, in particular sports shoes, comprising two textile tubular elements used in the construction of the upper and possibly the sole of said footwear articles, and the methods of manufacturing such footwear articles. Prior art

[0002] Conventional footwear articles generally comprise an upper and a sole structure. The upper is secured to the sole structure and forms a void within the footwear article to comfortably receive and secure a foot. The sole structure is secured to a lower area of ​​the upper, and operatively disposed between the ground, and the upper.

[0003] In athletic footwear, the sole structure may include a wear sole and a midsole. The midsole often includes a polymer foam material that absorbs shock from the ground upon impact to lessen the effects on the foot and leg during walking, running, or other ambulatory activities. The sole structure may also include a liner positioned near the bottom surface of the foot to enhance the comfort of the footwear.

[0004] The soles are traditionally joined to the uppers using a so-called Strobel assembly in which the various sole elements (insole, midsole and outsole in particular) are assembled. The manufacturing processes for a conventional shoe require dozens of steps, and produce a lot of waste from the cutting of materials.

[0005] It is sought to simplify the manufacturing processes of footwear articles, in particular by reducing the number of steps and / or the energy and material consumption. This problem is also part of the search for a manufacturing process that can be implemented as close as possible to the place of use of the footwear article in order to reduce its carbon impact, facilitate stock management, and allow the personalization of the footwear article.

[0006] One solution is to eliminate the sewing steps required to shape the initially flat upper in three dimensions. The upper is obtained from the assembly of one or a few pieces, and no longer from multiple pieces joined together by sewing.

[0007] Footwear articles are thus known comprising a textile tubular element comprising thermofused textile portions forming at least part of the upper. It is thus sought to improve these footwear articles so that they are light, flexible, and breathable, while offering satisfactory resistance to abrasion and tearing, and comfortably fitting the shape of the foot.

[0008] Such footwear articles, despite a particular construction, must also offer varied designs respecting the technical criteria set out above, while limiting the aesthetic and / or functional component(s) necessary for their manufacture.

[0009] It may thus be sought to form one or more viewing areas of a particular portion of the footwear article from the exterior of the latter. It is thus proposed to melt thermofusible threads and to form a transparent film-forming area. However, this type of film-forming area reduces the breathability and flexibility of the upper when the thermofusible monofilament threads have a large diameter or the abrasion / tear resistance when the thermofusible monofilament threads have a small diameter. In addition, when the upper comprises an inner layer and an outer layer comprising thermofusible threads, the latter adhere to the inner layer when they are thermofusible, further stiffening the treated area of ​​the upper.

[0010] It is thus sought to form a viewing area which does not alter the permeability, or at the very least limits the reduction in permeability, and which retains good flexibility of the region of the upper comprising it, as well as good resistance to abrasion and tearing, in particular when a through opening is arranged in this viewing area.

[0138] 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 not heat-melted.

[0139] This arrangement makes it possible to form tear-resistant through openings.

[0140] This arrangement also improves the flexibility, breathability and enhances the display / visualization function of the main, or additional, external, or internal textile portion.

[0141] In a first exemplary embodiment, the main, or additional, external textile portion does not comprise a through opening and the main, or additional, internal textile portion comprises one or more through opening(s), in particular A and / or B, more particularly B.

[0150] The inventors have determined that this arrangement makes it possible to implement said monofilament yarn on a textile loom, in particular by knitting, while offering a good compromise between rigidity and flexibility.

[0151] In addition, this type of thread provides shine.

[0152] In this text, a trilobed cross-section is understood to mean that the cross-section of a monofilament yarn comprises at least three sides.

[0153] Advantageously, a trilobed cross-section has a substantially triangular general shape.

[0154] The subject of the present invention is, according to a second aspect, a method of manufacturing a shoe, in particular a sports shoe, in particular according to any one of the variant embodiments according to a first aspect of the invention, said method advantageously comprising the steps: i) an external textile tubular element and a textile tubular element are provided internal of which at least one of said internal and external textile tubular elements comprises at least one thermofusible textile portion, the external textile tubular element comprises at least one external textile main portion and the internal textile tubular element comprises at least one internal textile main portion, the internal textile tubular element is arranged at least in part in a receiving void of the foot of the external textile tubular element so that said external and internal textile tubular elements are at least in part superimposed, and that the internal and external textile main portions are at least in part superimposed, the external textile main portion comprising one or more transparent and / or translucent monofilament thread(s), in particular having a melting temperature Tf or degradation temperature Td; ii) the inner and outer textile tubular elements are heated to a heating temperature Te so as to at least partially melt said at least one thermofusible textile portion, in particular the temperature Tf or Td is higher than the heating temperature Te; iii) a rod is obtained comprising at least a portion of the external textile tubular element and at least a portion of the internal textile tubular element, at least one of said internal and external textile tubular elements comprises at least one thermofused textile portion, and said at least one external textile main portion forms a viewing area of ​​the internal textile main portion.

[0155] In one example, the method comprises a step of securing a sole structure to the outer textile sole portion of the outer textile tubular element or to the upper obtained in step iii).

[0156] In one example, the method comprises a thermoforming or thermocompression step during which one or more sole element(s) may be arranged between the inner textile sole portion of the inner textile tubular element and the outer textile sole portion of the outer textile tubular element or in contact with the textile sole portion of the outer textile tubular element, in particular for joining by gluing, more particularly by gluing by one or more thermofused textile portion(s).

[0157] The thermoforming step, in particular the heating step ii), advantageously comprises the heat-fixing of the internal and external covering textile parts at least in part of the foot of the internal and external textile tubular elements to the shape of a preform in the general shape of a foot. The internal and external textile tubular elements are held during their cooling under pressure against the preform so as to match and retain the shape of the preform. The at least partly heat-meltable thread(s) may be glued together.

[0158] The preform in the general shape of a foot is preferably arranged in the volume receiving the foot of the internal textile tubular element, the textile tubular elements being at least partially superimposed.

[0159] The thermocompression step, in particular the heating step (ii), advantageously comprises the arrangement of the internal and external textile tubular elements, with one or more sole element(s), in a mold. Preferably, an inflatable bladder (in particular made of silicone), in particular having a substantially foot-shaped shape, is arranged in the foot-accommodating volume of the internal textile tubular element, which internal textile tubular element is at least partly superimposed with the external textile tubular element. During thermocompression, the inflatable bladder is inflated, for example to an inflation pressure ranging from approximately 3 bars to approximately 6 bars, in order to compress the internal and external textile tubular elements, and possibly the sole element(s), against the internal 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 so as to melt and cause the targeted thermofusible textile material(s) to flow more or less.

[0160] Indeed, the shoe may comprise one or more textile materials which are heat-fusible by nature, but which are not heat-fused during the manufacture of the shoe. This textile material is thus considered to be non-heat-fusible or non-heat-fused according to the invention.

[0161] For example, the heating temperature is greater than or equal to 110°C and less than or equal to 200°C, in particular ranging from 110°C to 160°C.

[0162] An internal or external textile tubular element may be knitted on a small diameter circular knitting machine. It may be a weft or warp knit, preferably a weft knit.

[0163] After step (iii), the method may comprise a step of fixing one or more sole element(s) to the external textile sole part of the external textile tubular element, for example rubber portions secured by gluing.

[0164] It is also possible to screw metal spikes into protrusions projecting from the external face of the external textile part of the sole of the external textile tubular element to form crampons.

[0165] The sole element which can be arranged between the inner and outer textile sole parts respectively of the inner and outer textile tubular elements is a wear sole or a shock-absorbing element, for example having a Shore A hardness greater than 30 and less than 80.

[0180] For the purpose of reference of the terminology used in this text and associated with a shoe, the shoe 10 shown in [Fig.l] will be described below. The shoe 10 can be divided into three general regions: a forefoot region 12, a midfoot region 14 or also called midfoot 14; a heel or rearfoot region 16. The forefoot region 12 generally includes portions of the shoe 10 corresponding to the toes and the joints connecting the metatarsals to the phalanges. The midfoot region 14 generally includes portions of the shoe 10 corresponding to the arch of the foot. The heel or rearfoot region 16 generally corresponds to the rear portions of the foot, and notably includes the calcaneus bone.The shoe 10 also includes a lateral side 17 and a medial side 18, which extend through each of the forefoot 12, midfoot 14, and heel 16 regions and correspond to opposite sides of the shoe 10. More particularly, 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 insertion opening 5 for accessing the foot receiving (or reception) volume 6.

[0181] The shoe 10 comprises an instep area 11 extending substantially centered between the lateral side 17 and the medial side 18 in the midfoot region and optionally partially in the forefoot region 12.

[0182] The shoe 10 also comprises a longitudinal axis L and a transverse axis T, in particular substantially perpendicular to the axis L. The shoe 10 also comprises a front edge 19a and a rear edge 19b. The footwear article 10 comprises an upper 15 and a sole structure, in particular a wear sole 20.

[0183] 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 insertion opening 5, and the foot receiving or accommodating volume 6, may be applied to the sole structure 20, to the upper 15, and to their individual elements, such as for example, in a non-limiting manner, to the internal and external textile tubular elements and to their respective textile foot covering parts and their respective textile sole parts.

[0184] [Fig.2] schematically represents for reference purposes, the different regions which may comprise a sole structure 20, corresponding to the regions defined in [Fig. 1].

[0185] [Fig.3] schematically represents a first example of a tubular element inner textile 50 and a first example of a separate outer textile tubular element 60, each in a knitted textile piece, in particular each in a knitted sock. The inner textile tubular element 50 comprises an inner textile covering portion 52 of the foot and an inner sole textile portion 54, as well as an angled portion 56 for forming a heel region. In this specific example, the inner textile covering portion of the foot 52 extends in the forefoot, midfoot, and heel regions, and this from the lateral side to the medial side. In this specific example, the inner sole textile portion 54 extends between a front edge and a rear edge in the forefoot, midfoot, and heel regions, and this from the lateral side to the medial side.

[0186] The outer textile tubular element 60 comprises an outer textile foot covering portion 62 and an outer textile sole portion 64, as well as an angled portion 66 for forming a heel region. In this specific example, the outer textile foot covering portion 62 extends in the forefoot, midfoot, and heel regions, and this between the lateral and medial sides. In this specific example, the outer sole textile portion 64 extends between a front edge and a rear edge in the forefoot, midfoot, and heel regions, and this between the lateral and medial sides.

[0187] The internal textile tubular element 50 is arranged in the receiving volume 61 of the external textile tubular element 60, they are thus substantially superimposed at least in part. The internal 50 and external 60 textile tubular elements are preferably placed on a foot-shaped preform (in particular the preform is arranged in the receiving volume of the foot of the internal textile tubular element 50), then undergo a thermoforming or thermocompression step during which the thermofusible textile portions of said internal textile tubular elements 50 and 60 are thermomelted so as to secure the internal textile tubular element 50 to the external textile tubular element 60, and shape the assembly to the shape of the foot-shaped preform. The internal 50 and external 60 textile tubular elements are then cooled on the preform preferably in order to freeze said shape.

[0188] During the thermoforming step, the preform is preferably rigid.

[0189] In the thermocompression step, the preform is an inflatable bladder (particularly in a silicone or polyurethane material which can be inflated and deflated, and is therefore reusable). The heating temperature applied during the thermocompression step is determined so as to melt the targeted thermofusible material(s) more or better. Thus, depending on the desired effects, threads can be glued together 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.

[0190] One or more sole elements, for example a wear sole or a flexible sole element in a material having a Shore A hardness of between 40 and 70, is / are arranged between the inner sole textile part 54 and the outer sole textile part 64. Preferably, the inner 54 and outer 64 textile sole parts consist essentially of thermofusible thread(s) or each comprise at least 80% by mass of their total mass of thermofusible thread(s). Preferably, during the thermocompression step, the at least partly thermofusible or entirely thermofusible thread(s) of the inner and outer textile sole parts (54, 64) are thermofused. The inner and outer textile tubular elements 50 and 60 being preferably separate knitted pieces, they may have different configurations. For example, as shown in [Fig. 3], the outer textile covering portion of the foot 62 covers less of the foot than the inner covering portion of the foot 52, in particular the outer textile covering portion of the foot 62 does not include an instep area and covers less of the ankle than the inner textile covering portion 52.

[0191] [Fig.4] schematically represents a second example of an internal textile tubular element 70 and a second example of an external textile tubular element 80 which are of unitary textile construction, in particular in a single U-shaped knitted piece. In this specific example, the internal and external textile tubular elements 70 and 80 are in knitted textile connection at the levels of their foot introduction openings corresponding to the fold line 75 from which the internal tubular element 70 is returned into the foot reception volume 85 of the external textile tubular element 80. The internal 70 and external 80 textile tubular elements are advantageously knitted socks, and each have a bent portion 72, 82.

[0192] 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 70 and external 80 textile tubular elements then undergo a thermoforming or thermocompression step during which thermofusible textile portions are thermomelted to secure said internal and external textile tubular elements. 70,80 between them and form them to form the preform.

[0193] The inner sole textile portion 54 or 72, and the outer sole textile portion 64 or 82, are shown as being configured to be arranged strictly under the foot in Figures 3 to 5. In another example, depending on the configuration of the sole structure chosen, the inner sole textile portion 54 or 72, and / or the outer sole textile portion 64 or 82, envelop(s) a portion of the top of the foot and all or part of the perimeter of the foot. The thermocompression step can take place as described with reference to the first examples of inner and outer textile tubular elements (50, 60).

[0194] 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 superimposed internal and external textile main portions, according to the invention.

[0195] [Fig.6] schematically represents a shoe 100 comprising an upper 110 and a sole 120. The shoe 100 comprises an internal textile tubular element 130 arranged at least partly in the foot receiving volume of an external textile tubular element 140. The upper 110 comprises the internal textile covering part of the foot 132 of the internal textile tubular element 130 and the external textile covering part of the foot 142 of the external textile tubular element 140.

[0196] Advantageously, the outer textile covering portion of the foot 142 comprises an outer textile main portion 144 which extends partly into the forefoot region disposed between the medial and lateral sides and the forefoot regions disposed on the lateral side and on the medial side, and partly into the midfoot regions disposed on the medial and lateral sides. In particular, the outer textile main portion 144 does not extend into the instep area 102. Advantageously, the outer textile main portion 144 occupies at least 50%, preferably at least 80% of the total surface area occupied by the forefoot and midfoot regions of the outer textile covering portion of the foot 142. The outer textile main portion 144 comprises, in particular is essentially made up of, transparent monofilament yarns forming a substantially continuous viewing area extending into said regions.Said monofilament yarns are, in a non-limiting example, transparent polyethylene terephthalate monofilament yarns having a diameter of the order of 0.50 mm.

[0197] Advantageously, the external textile main portion 144 comprises through openings 146, in particular through openings A as defined above, more particularly each having at least one dimension da greater than or equal to 2 or 3 mm. Said through openings 146 are preferably knitted at the same time as the external textile tubular element 140.

[0198] Advantageously, the internal textile covering portion of the foot 132 comprises an internal textile main portion 134 partially superimposed with the external textile main portion 144. In this example, the internal textile main portion 134 does not comprise a through opening. Advantageously, the internal textile covering portion of the foot 132 comprises an internal textile main portion 134 which extends at least partially in the forefoot regions arranged between the lateral and medial sides and on the lateral and medial sides, as well as in the midfoot regions on the lateral and medial sides. The internal textile covering portion of the foot 132 also extends into the instep area 102. The instep area 102 of the internal textile covering portion of the foot 132 thus forms a part of the external face of the upper 110.Advantageously, the inner textile main portion 134 occupies at least 50%, preferably at least 80%, of the total surface area occupied by the forefoot and midfoot regions arranged on the lateral and medial sides, and the forefoot region arranged between the lateral and medial sides, of the inner textile covering part of the foot 132. The inner textile main portion 134, in particular its outer face 134b, is visible from the outer face 144b of the outer textile main portion 144. In particular, the color (here gray) and the textured appearance of the textile of the inner textile main portion 134 are visible from the viewing area formed by the outer textile main portion 144.

[0199] [Fig.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.

[0200] The outer textile tubular element 250 comprises an outer textile foot covering portion 260 comprising an outer textile main portion 270 consisting essentially of transparent monofilament yarns and extending partly 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 outer textile foot covering portion 260. Said monofilament yarns are, in a non-limiting example, transparent polyethylene terephthalate monofilament yarns having a diameter of the order of 0.35 mm, not intended to be heat-melted.

[0201] The inner textile tubular member 200 includes an inner textile foot covering portion 210 including an inner textile main portion 220 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 inner textile foot covering portion 210.

[0202] In this specific example, the main internal textile portion 210 comprises knitted stitches separated from each other by spaces forming through openings, in particular through openings B as described above, more particularly each having at least one dimension of the order of approximately 1 mm or less. The main external textile portion 250 thus forms a viewing area of ​​the external face of the first internal textile portion 210. It is possible to view the color, the pattern(s), the knitted texture of the main internal textile portion 210.

[0203] In this specific example, the outer textile main portion 270 does not comprise thermofused yarns so that the stitches knitted in the latter are movable relative to each other, the monofilament yarn being able to slide in said stitches. The outer textile main portion 270 thus retains a certain flexibility and is breathable, it is possible to evacuate perspiration and heat accumulated between the inner and outer textile main portions (210,270), and in the foot reception volume.

[0204] In this specific example, the outer textile main portion 270 is shown with a single type of mesh pattern (i.e., binding of the threads together) which is repeated over its entire surface. However, the outer textile main portion 270 may comprise different mesh patterns arranged in distinct areas.

[0205] In this specific example, the outer 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 unitary knitted construction with the outer textile tubular element 250 also knitted.

[0206] In this specific example, the outer textile tubular element 260 comprises a single outer textile main portion 270. However, the outer textile tubular element 260 could comprise one or more separate additional outer textile portion(s), in particular the outer textile main portion and the additional outer textile portion(s) are separated from each other by one or more intermediate outer textile portion(s) not comprising transparent and / or translucent monofilament yarn(s).

[0207] By way of non-limiting example, the external covering textile portion of the foot 260 comprises heat-meltable knitted textile portions 262 which will be melted during the thermocompression step, preferably mixed with non-heat-meltable knitted textile portions.

[0208] Preferably, the inner and outer textile sole parts consist essentially of thermofusible thread(s) which is / will be thermofused during the thermocompression step.

[0209] The thermofusible yarns are, in a non-limiting example, multifilament yarns.

The external textile tubular element 350 comprises an external textile covering part of the foot 360 comprising an external textile main portion 370 consisting essentially of transparent monofilament yarns and extending partly 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 textile covering part of the foot 360.Said monofilament threads are, in a non-limiting example, transparent polyethylene terephthalate monofilament threads having a diameter of the order of 0.35 mm, not intended to be heat-melted.

[0211] The inner textile tubular element 300 comprises an inner textile foot covering portion 310 comprising an inner textile main 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 inner textile foot covering portion 320.

[0212] In this specific example, the internal textile main portion 310 comprises knitted through openings 315, in particular knitted through openings A as described above, more particularly having at least one dimension of the order of approximately 3-4 mm. The external textile main portion 350 thus forms a viewing area of ​​the external face of the internal textile main portion 310. It is possible to view the color, the pattern(s), the knitted texture as well as the through openings 315 of the internal textile main portion 310.

[0213] The through openings 315 of the main internal textile portion 310 make it possible to view the receiving volume of the upper 380, in particular portions of the foot. [Fig. 9] schematically represents a fifth example of an internal textile tubular element 400 arranged partly in the foot receiving volume of a fifth example of an external textile tubular element 450. The external textile tubular element 450 comprises an external textile covering part of the foot 460 comprising an external textile main portion 470 consisting essentially of translucent monofilament yarns and extending partly in the midfoot region on the lateral and medial sides, and in the forefoot region between the lateral and medial sides, of the external textile covering part of the foot 460.

[0214] The inner textile tubular element 400 comprises an inner textile foot covering portion 410 comprising an inner textile portion 420 extending partly into the midfoot region on the lateral and medial sides, and into the region forefoot between the lateral and medial sides of the inner textile covering portion of the foot 410.

The external textile main portion 470 thus forms a viewing area of ​​the external face of the internal textile main portion 420. It is possible to view the color, the pattern(s), as well as the knitted texture of the internal textile main portion 420.

[0216] In this specific example, the external textile main portion 470 comprises knitted through openings 475 A as defined above in the present text, in particular having at least one dimension of approximately 3 to 5 mm.

[0217] Advantageously, the through openings 475 of the outer textile main portion 470 have at least one dimension greater than at least one of the dimensions of each of the through openings B of the inner textile main portion 420.

[0218] In this exemplary embodiment, the knitted through openings are distributed in the forefoot region disposed between the lateral and medial sides, and partially border the outer textile main portion 470 in the midfoot regions on the lateral side and on the medial side.

[0219] For example, the outer foot covering textile portion 460 comprises first and second sets 462, 463 of through openings 476 forming textile lacing loops or bridges 477 in the instep area. A lacing loop 476 is delimited by two adjacent through openings 476 arranged transversely relative 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.

[0220] In [Fig.9], the outer textile main portion 470 extends substantially continuously in the forefoot and midfoot regions. The outer textile main portion 470 could alternatively be arranged only in the forefoot region between the lateral and medial sides, and the outer textile tubular element 450, in particular its outer covering textile part 460, could comprise a (first) additional outer textile portion arranged in the midfoot region on the lateral side and another (second) additional outer textile portion arranged in the midfoot region on the medial side. The outer textile main and additional portions are in this case distinct from each other, and possibly separated by one or more intermediate textile portions not comprising transparent monofilament yarn.The same alternative arrangement may be retained with the internal textile tubular element 410.

The external textile tubular element 550 comprises an external textile covering part of the foot 560 comprising an external textile main portion 570 consisting essentially of transparent monofilament yarns and extending partly in the forefoot, midfoot and rearfoot regions, and this on and between the lateral and medial sides, of the external textile covering part of the foot 560.

[0222] The inner textile tubular member 500 includes an inner textile foot covering portion 510 including an inner textile main portion 520 extending partially into the forefoot, midfoot, and heel regions over and between the lateral and medial sides of the inner textile foot covering portion 510.

[0223] In this specific example, the internal textile main portion 510 comprises through openings, in particular through openings B as defined above, more particularly having at least one dimension of the order of approximately 1 mm. The external textile main portion 550 thus forms a viewing area of ​​the external face of the internal textile main portion 510. It is possible to view the color, the pattern(s), as well as the texture, in particular knitted, of the internal textile main portion 510.

[0224] In this specific example, the external textile main portion 570 comprises through openings 575, in particular through openings A as defined above, more particularly having at least one dimension of approximately 3 to 5 mm, and have at least one dimension greater than at least one of the dimensions of the through openings of the internal textile main portion 510.

[0225] 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 portion of the foot 560.

[0226] Preferably, the inner sole 530 and outer sole 580 textile parts are essentially made of single-component thermofusible multifilament yarns, in particular thermofusible polyurethane. These yarns are therefore thermofused onto the finished shoe.

[0227] [Fig. 12] schematically and partially represents a third example of a shoe according to the invention 700 comprising an internal textile tubular element 705 arranged partly in the volume for receiving a foot of the external textile tubular element 750.

[0228] The external textile tubular element 750 comprises an external textile covering part of the foot 760 comprising an external textile main portion 770 consisting essentially of transparent monofilament threads and extending partly into the forefoot and midfoot regions; and this on and between the lateral and medial sides.
