Description

Technical Field

[0001] The present invention relates to sole structures comprising fully or at least partially heat-fused fabric sole components, as well as shoes comprising such structures, methods of manufacturing such structures, and footwear comprising the like.

[0002] Traditional shoes typically consist of an upper and a sole structure. The upper is attached to the sole structure and forms a space within the shoe to comfortably accommodate and secure the foot. The sole structure is attached to the lower area of ​​the upper and is operatively positioned between the shoe and the ground. In athletic shoes, the sole structure may include an outsole and a midsole. The midsole typically comprises a polymer foam material that absorbs impact with the ground upon impact, reducing the impact on the foot and leg during walking, running, or other walking activities. The sole structure may also include a lining located near the lower surface of the foot to enhance shoe comfort. The sole is traditionally attached to the upper using a strobel, during which the various sole components (particularly the insole, midsole, and outsole) are assembled. Traditional shoe manufacturing methods require dozens of steps and generate significant waste due to material cutting.

[0003] People are seeking to simplify the manufacturing processes for shoes, particularly by reducing the number of steps and / or lowering energy and material consumption. This is also part of the search for manufacturing methods that can be implemented as close as possible to where the shoes will be used, to reduce their carbon impact, facilitate inventory management, and allow for customized shoes.

[0004] One solution is to eliminate the stitching steps required to form the initial flat upper in three dimensions. The upper is assembled from one or more pieces, rather than stitched together from multiple pieces.

[0005] Patent document WO 2019 / 234374 A1 discloses a first fabric bootie, partially heat-meltable, formed directly at the exit of a textile machine (e.g., a knitting machine) in three dimensions, used as an upper, which is then attached to the outsole. The upper is reinforced by arranging a second heat-melt fabric bootie in a three-dimensional manner around the first bootie, improving delamination resistance by wrapping the joint between the first bootie and the outsole. The components, including the first fabric bootie, the second fabric bootie, and the outsole, are heat-treated to melt the heat-melt yarns and shape the upper. This manufacturing method simplifies the process by significantly reducing the number of manufacturing steps. However, such a shoe, comprising an upper formed by stacking two, three, or four fabric booties, may be too heavy for certain activities, particularly sports, requiring a specific weight for intended use. For example, the standard weight of a soccer practice shoe is approximately 165 to 250 grams.

[0006] Furthermore, thermoforming of the two flexible components, namely the rigid component between the two fabric inner boots (in this particular case, the outsole), can lead to reproducibility difficulties in positioning the components together, thereby increasing the scrap rate.

[0007] Furthermore, the outsole and / or midsole are obtained via injection molding, where the amount of polymer material and the number of different colors are practically limited to two due to cost considerations. Material and aesthetics, particularly color, vary depending on specific areas of the sole, and are constrained by the costs associated with adjusting the sole injection method. For ease of demolding, the sole needs to have a substantially uniform overall thickness. Therefore, material grooves in the inner surface of the sole are molded so that the amount of injected material is uniform across the entire surface of the sole, resulting in a substantially constant sole thickness.

[0008] Patent document US 2016 / 0206046 A1 discloses a method for manufacturing a shoe sole structure, which includes embossing a flat fabric sheet to locally deform the fabric sheet to form a stud. The embossed fabric sheet has a constant thickness equal to its initial thickness before embossing. The area of ​​the embossed fabric sheet facing the stud is not flat but hollow. The stud is formed as a hollow structure and filled with foam inserts for reinforcement. This sole structure is fragile because it requires filling with studs for reinforcement. Furthermore, the manufacturing process is complex because the tool used for embossing the fabric sheet is a foam insert, thus requiring a perfect fit between the embossed sheet and the foam insert stud.

[0009] Therefore, there is a need for a sole structure that is simple to manufacture, has good mechanical properties, can be freely functionalized in terms of material, color, or the latter's location, and offers a wide range of choices in its shape, especially in possible sole cavities.

[0010] Therefore, it is also necessary to reduce the weight of the shoe while improving its comfort by allowing various possible functions (reinforcement, cushioning, hard toe, etc.). This is about locally reducing the volume of the shoe while maintaining the normally required properties such as abrasion resistance, delamination resistance, and flexibility. Summary of the Invention

[0011] The object of the present invention is to provide a method for manufacturing a shoe sole structure according to a first aspect, comprising:

[0012] (i) Provide at least one fabric sole component having an outer surface comprising one or more yarns that are at least partially heat-fusible;

[0013] (ii) Arranging the fabric sole component in a mold structure having a sole cavity;

[0014] (iii) An inflatable air bladder is provided in the mold structure, and the air bladder is inflated to press the outer surface of the fabric sole component directly or indirectly against the sole cavity, and the fabric sole component is heated to melt at least a portion of the heat-fusible yarn and substantially mold the sole cavity onto the outer surface of the fabric sole component; and

[0015] (iv) Obtain a sole structure comprising at least one heat-pressed fabric sole component.

[0016] The inventors were surprised to discover that by using a thermo-pressing method performed with an inflatable airbag, a sole structure could be formed from at least one fully or partially heat-fusible fabric sole component.

[0017] The inventors have observed that the at least one fabric sole component includes air arranged between the yarns forming its structure, which allows air to escape during the hot pressing step and thus facilitates its thermoforming. The airflow through the fabric sole component during hot pressing balances the distribution of the hot-melt material in the sole cavity of the mold. Advantageously, the at least one hot-pressed fabric sole component is molded in a regular manner and without any air bubbles or hollow areas.

[0018] Advantageously, a sole structure with a sole cavity can be formed, the sole cavity comprising one or more negative cavities and / or positive cavities. In particular, the corresponding sole cavity of the mold structure is filled with a hot-melt material from at least partially heat-meltable yarn, thereby forming a positive or negative cavity on the sole structure, particularly on its outer surface.

[0019] Therefore, the positive or negative cavity is not formed by embossing the fabric sole component. Thus, compared to embossed fabric sole structures, the sole structure according to the invention exhibits improved mechanical strength (flexural strength, puncture strength), foot support, hardness, and abrasion resistance, eliminating the need for complementary reinforcing members to fill the formed reinforcement grooves.

[0020] Preferably, the sole structure according to the invention has a substantially fully molded volume. In particular, the sole cavity of the molded structure is designed for direct or indirect contact with the outer surface of the fabric sole component.

[0021] Advantageously, the sole structure can be functionalized using materials with different mechanical (elasticity, hardness, etc.) and aesthetic (color, yarn count, etc.) properties. This is achieved in a differentiated and localized manner throughout the entire volume of the sole structure, which is impossible for soles obtained through conventional injection methods, while meeting the mandatory profitability requirements related to the cost of manufacturing molds.

[0022] Preferably, the inflatable airbag is arranged between the mold structure and the inner surface of the fabric sole component, such that the inflatable airbag is in direct or indirect contact with the inner surface of the fabric sole component.

[0023] The mold structure preferably consists of multiple parts, such as an upper right mold part and an upper left mold part receiving an inflatable airbag, a possible upper, and a lower mold part including a sole cavity that receives at least one fabric sole component. Preferably, the mold structure may also consist of two parts, such as an upper part receiving an inflatable airbag, an optional upper, and a lower part including a sole cavity and receiving at least one fabric sole component. The latter configuration optimizes the joint plane and the quality of the finished product.

[0024] In one embodiment, a master mold comprising one or more positive cavities and optionally one or more negative cavities, particularly in the form of a core (of one or more components), is machined or 3D printed to refine the pattern of the one or more positive cavities. Preferably, the master mold is a mold of at least one metal, or a mold of an alloy of said metal.

[0025] The sub-mold corresponding to the mold structure according to this document is obtained through a secondary molding process (overmolding) of the master mold, and therefore includes one or more negative cavities and possibly one or more positive cavities. The sub-mold is preferably a metal mold (e.g., a casting mold). The sub-mold may also be made of a reinforcing polymeric material. In the latter case, it may be a composite material.

[0026] This configuration allows for greater precision and finesse in the cavities formed on the sole structure, as well as in the bootie and / or auxiliary fabric linings. In fact, it makes the positive cavity shapes of the pattern and / or master mold more complex and therefore less accessible compared to recessed negative cavities.

[0027] The master mold and / or the sub-mold (both) can be divided into two or three parts, or into multiple parts as needed, to achieve satisfactory design accuracy and / or cavity shape.

[0028] In another embodiment, the mold structure is directly machined or 3D printed. The mold structure described herein can be configured to manufacture only the sole structure of a shoe (footwear) or to manufacture both the sole structure and the upper, as will be explained below. Therefore, in addition to the sole cavity, the mold structure may also include an upper cavity comprising one or more negative cavities and / or positive cavities.

[0029] Mold structures, particularly those for manufacturing shoes, can be divided into two or three parts, for example including: an upper part that at least partially receives the upper and a lower part that at least partially receives the upper and sole structure, the bottom part including an outer lower part and an inner lower part.

[0030] Preferably, the sole structure includes substantially opposite inner and outer surfaces.

[0031] Preferably, the fabric sole component comprises a substantially opposing inner surface and an outer surface.

[0032] Preferably, when the heat-pressed fabric sole component and / or sole structure is part of or the outsole, the outer surface of the at least one fabric sole component and / or sole structure is preferably oriented toward the ground and can be in direct contact with the ground. Preferably, the inner surface of the at least one fabric sole component and / or sole structure is oriented toward the user's foot.

[0033] The sole construction and / or fabric sole component (both) may include a heel portion and / or a forefoot portion and / or a midfoot portion, particularly extending between the inner and outer edges of the shoe that include the sole construction or fabric sole component.

[0034] The sole structure and / or fabric sole component may extend, on the one hand, between the rear and front edges of the shoe, including the sole structure or fabric sole component, and / or on the other hand, between the outer and inner edges.

[0035] Preferably, the inflatable air bladder applies pressure directly or indirectly to the inner surface of the fabric sole component and pushes the fabric sole component so that its outer surface directly or indirectly contacts the sole cavity of the mold structure. Preferably, the fabric sole component is thermally pressed between the sole cavity of the mold structure and the inflated air bladder.

[0036] Preferably, the inner surface of the heat-pressed fabric sole component is substantially flat. In practice, the inflatable bladder preferably has a substantially smooth surface, such that this surface directly or indirectly contacts the inner surface of the fabric sole component, flattening it. The pressure applied by pushing the inflatable bladder contributes to this flattening.

[0037] Preferably, after the hot-pressing step iii), the method includes the step of cooling the mold structure comprising at least one hot-pressed fabric sole component. This step allows the fabric sole component to remain in its hot-pressed state.

[0038] The sole structure may include or be composed of one or more fabric sole components, particularly hot-pressed sole components, and in particular one or more fabric sole components forming one or more outsole components and / or midsole components and / or insole components.

[0039] Preferably, the sole structure is an outsole structure, a midsole structure, or a combination thereof.

[0040] Fabric sole components can be one or more knitted fabrics, one or more garment fabrics, one or more nonwoven fabrics, one or more woven fabrics, one or more yarn / fiber arrays, or a combination thereof.

[0041] Yarn / fiber arrays can be obtained, for example, through additive manufacturing.

[0042] Preferably, the sole structure includes at least one knitted fabric sole component.

[0043] Preferably, the sole structure comprises one or more fabric sole members, particularly those heat-pressed in step iii), or consists of at least one or more fabric sole members, particularly those heat-pressed in step iii), associated with one or more auxiliary sole members optionally heat-pressed in step iii). The auxiliary sole members can be configured to provide one or more specific cushioning, rebound, or reinforcement functions. The auxiliary sole members can be fabrics (knitted fabrics, and / or clothing fabrics, and / or nonwoven fabrics, and / or one or more woven fabrics, and / or yarn / fiber arrays) or foam members or polymer films or cushioning members, such as in the form of donuts. The auxiliary sole members can be heat-pressed together with the fabric sole members in step iii), or added to the at least one heat-pressed fabric sole member after step iii), for example, by bonding.

[0044] Preferably, the fabric sole component is one or more, particularly at least partially or completely overlapping, knitted fabrics. The knitted fabric can be weft-knitted or warp-knitted. The knitted fabric can be three-dimensional, i.e., comprising an upper layer and a lower layer knitted together by at least one knitting yarn.

The fabric sole component also includes one or more fabric branches (partially heat-melted and optionally heat-pressed) extending substantially vertically from the fabric sole portion, particularly one or more outer fabric branches extending from the outer edge of the sole portion and / or one or more inner branches extending from the inner edge of the sole portion. Preferably, each branch includes one or more first ends connected to the outer or inner edge of the fabric sole portion, and one or more second (partially free) ends. The second ends each include through-holes, particularly eyelets, for example, for the passage of elongated components such as shoelaces.

[0116] In a third variation, the method includes providing an auxiliary fabric lining comprising one or more at least partially heat-fusible yarns having space for accommodating feet and at least partially receiving the main fabric lining.

[0117] In one embodiment, the auxiliary fabric lining undergoes a thermoforming, particularly a hot-pressing, step, especially during or independent of step iii), for example, before or after step iii). The melting of the at least partially heat-fusible yarn allows the formation of the shoe upper.

[0118] In one embodiment, when the heat pressing of the auxiliary fabric lining occurs during step iii), the fabric sole component, the main fabric lining, and the auxiliary lining are heat-pressed together, particularly simultaneously thermoformed. This arrangement allows the fabric sole component to be attached to the main fabric lining on one hand and to the auxiliary lining on the other, as well as to attach the main lining and the auxiliary lining together.

[0119] In one embodiment, when the hot pressing of the auxiliary lining occurs independently of step iii):

[0120] - The secondary lining can be heat-pressed independently of the fabric sole components, and can be done independently or simultaneously with the main lining, and then assembled with the sole structure, particularly by adhesive or thermal bonding, stitching, or any equivalent technique; or

[0121] - The secondary lining and the primary lining can be heat-pressed together with the sole structure, which includes heat-pressed sole components (this also allows for the attachment of the sole structure to the primary and secondary linings, as well as the shaping of the upper).

[0122] Preferably, when the secondary lining and the primary lining are thermoformed together, particularly when they are hot-pressed, they at least partially overlap, with the at least one fabric sole component arranged between the secondary lining and the primary lining.

[0123] In one embodiment, the secondary lining has a single fabric structure, particularly a knitted or woven structure, especially a knitted structure. In particular, the secondary lining and the main lining are two separate fabric pieces.

[0124] In one embodiment, the auxiliary fabric lining and the main fabric lining have a single fabric structure, particularly a knitted structure, such as a single fabric piece, especially a knitted piece. The fabric piece may be generally L-shaped or U-shaped. Preferably, the auxiliary lining and the main lining are connected at their openings by fabric, particularly a knitted connection, to guide the foot into their respective internal spaces.

[0125] In one variation of the embodiment, the sole portion of the primary fabric lining and / or the sole portion of the secondary fabric lining comprises one or more at least partially heat-fusible yarns.

[0126] In the fourth variant, the sole structure in step iv) includes a heat-fused fabric material for at least partially heat-fused primary lining and / or a heat-fused fabric material for at least partially heat-fused secondary lining.

[0127] According to a fourth aspect, the present invention relates to a sole structure for shoes, particularly obtainable by a method for manufacturing a sole structure of any variation of an embodiment of the first aspect of the invention, comprising at least one at least partially heat-fused fabric sole member having substantially opposing inner and outer surfaces, the outer surface of the fabric sole member including a sole cavity, and the fabric sole member having a variable thickness.

[0128] Advantageously, at least partially heat-fused, especially heat-pressed, fabric sole components are not obtained by embossing fabric layers, and therefore do not have a substantially constant thickness corresponding to the thickness of the fabric layers.

[0129] In particular, the outer surface of the fabric sole component includes at least part or substantially all of the hot-melt fabric sole cavity.

[0130] Advantageously, the positive or negative cavities along the outer surface are not formed by corresponding (negative or positive) deformations along the inner surface of the fabric sole component. Therefore, the fabric sole component is more resistant to abrasion and mechanical deformation (bending and / or tensile deformation).

[0131] For example, at least partially heat-fused fabric sole components have a thickness e1 in a section including a positive cavity extending from its outer surface, which is greater than the thickness e2 in a section including a negative cavity receding from its outer surface.

[0132] Preferably, the base thickness e0 of the fabric sole component corresponds to the thickness in a section along the outer surface of the fabric sole component that excludes neither negative nor positive cavities.

[0133] Preferably, the ratio of the filling volume of at least one partially heat-melted fabric sole component to its total volume is greater than or equal to 80%, and more preferably greater than or equal to 90%.

[0134] In one embodiment, the at least partially heat-fused fabric sole component includes a sole portion extending substantially between a rear edge and a front edge and between a side edge and a middle edge. Preferably, the rear edge and the front edge substantially correspond to the rear edge and rear side edge of the shoe including the sole structure. Preferably, the medial edge and the lateral edge substantially correspond to the lateral edge and medial edge of the shoe including the sole structure.

[0135] In the first variant, the sole cavity includes at least one negative cavity or a positive cavity, and the inner surface of the fabric sole component includes at least one substantially flat area facing the negative cavity and the positive cavity.

[0136] This basically flat area can be understood as an area that does not include any recesses or hollow parts.

[0137] The inner surface of the sole component may be a generally non-planar shape, but includes at least one region arranged to partially face a negative or positive cavity on a flat inner surface.

[0138] For example, when the sole components form an outsole that includes a forefoot and a rearfoot, the forefoot may be slightly raised relative to the rearfoot. In fact, the outsole may rise from the toe of the upper to reach the upper.

[0139] In the second variant, the thickness (e1) of the section including the positive cavity of the fabric sole component is greater than the thickness (e2) of the section including the negative cavity of the fabric sole component.

[0140] In the third variation, the ratio of the mass of the hot-melt fabric material in the fabric sole component to the total mass of the fabric sole component is greater than or equal to 50%, preferably greater than or equal to 80%.

[0141] In the fourth variation, the fabric sole component is the outsole, which may optionally include one or more at least partially heat-fused fabric studs.

[0142] According to a fifth aspect, the present invention relates to a shoe comprising a sole structure of any variation of an embodiment of the fourth aspect of the invention.

[0143] In the first variant, the shoe includes at least a partially heat-fused main fabric lining.

[0144] In a second variation of the embodiment, the fabric sole component and the main fabric lining have a single fabric structure.

[0145] In a third variation of the embodiment, the at least partially heat-fused fabric sole component is a fabric envelope, including a sole portion and an outer portion for partially wrapping the foot.

[0146] In one embodiment, the at least partially heat-fusible fabric sole component includes one or more branches that extend substantially vertically from the outer and / or inner edges of the sole portion of the fabric sole component. Preferably, the branches are one or more fabrics, particularly the outer and / or inner branches comprising one or more yarns as defined herein, particularly one or more at least partially heat-fusible yarns, such that they can be at least partially heat-fusible.

[0147] Preferably, the branch includes a first end connected to an outer edge or an inner edge and a second (optionally free) end.

[0148] The second end of the outer branch converges toward the second end of the inner branch.

[0149] The second end may include a through hole, such as a channel eyelet, for the passage of elongated components (such as shoelaces).

[0150] In a fourth variation of the embodiment, the shoe includes at least partially heat-fused auxiliary fabric lining and has a space for accommodating the foot, the space at least partially receiving the main fabric lining.

[0151] In one embodiment variation, the fabric sole component includes a primary lining of hot-melt fabric material and / or a secondary lining of hot-melt fabric material.

[0152] In one embodiment variation, the shoe includes at least one at least partially heat-fused fabric viewing window, particularly comprising one or more at least partially heat-fused transparent or opaque yarns.

[0153] The main lining or auxiliary lining or fabric sole component according to the invention may include one or more at least partially heat-fused fabric viewing windows.

[0154] For example, the secondary lining includes at least a partially heat-fused fabric viewing window, which is arranged to face substantially the portion of the main lining. Thus, the main lining can be seen from the outside of the shoe through this window.

[0155] The embodiments, definitions, and variations thereof according to the first and / or second and / or third and / or fourth and / or fifth aspects of the present invention may be combined independently of each other unless otherwise specified.

[0156] Preferably, in this document, with reference to the sole structure or the method of manufacturing the shoe, the term "hot-meltable" refers to a component before hot-melting (which may be obtained during a thermoforming or hot-pressing step); with reference to an already obtained sole structure or shoe, the term "hot-melted" refers to the same component after its hot-melting.

[0157] Preferably, the shoe and / or sole structure according to the invention is a shoe and / or sole structure for sports activities, such as (but not limited to): football, basketball, hiking, running, cycling, ... Attached Figure Description

[0174] Figure 1 A first example of the fabric sole component 10 shown includes: a fabric sole support 12 having a substantially opposing inner surface 12a and an outer surface 12b; and a fabric functional region 20 extending from the outer surface 12b. Preferably, the fabric functional region 20 and the sole support 10 have a single fabric structure. Both the fabric sole support 12 and the fabric functional region 20 include one or more at least partially heat-fusible yarns.

[0175] A second example of the fabric sole component 30 includes: a fabric sole support 40 having a substantially opposing inner surface 40a and an outer surface 40b; and a fabric layer 50 disposed on the outer surface 40b, which in this particular example is continuous. Preferably, the fabric sole support 40 and the fabric layer 50 have a single fabric structure and both include one or more at least partially heat-fusible yarns. The fabric layer 50 may include more at least partially heat-fusible yarns than the sole support 40. When they have a single fabric structure, the distribution of at least partially heat-fusible yarns can be differentiated by the thickness of the fabric.

[0176] In these examples, both fabric sole components 10 and 30 are knitted fabrics with a single knitted structure. However, the fabric sole components can be combined with one or more other auxiliary sole components, particularly fabric or non-fabric (e.g., one or more polymer films) and / or one or more molded functional parts (e.g., made of foam and / or one or more reinforcements).

[0177] The sole structure 60 includes a hot-pressed fabric sole member 10 or 30 with the same sole cavity according to a given mold structure. In this specific example, the sole structure 60 is an outsole 70 and includes a substantially opposing inner surface 60a and an outer surface 60b. The sole structure 60 includes eight positive cavities 72, particularly studs, and negative cavities 74, particularly lateral grooves, enabling the softening of the outsole 70. The sole structure 60 has a longitudinal axis L extending substantially between the leading edge 62 and the trailing edge 64, and a transverse axis T extending substantially between the inner edge 66 and the outer edge 68. The axes T and L intersect and may be substantially perpendicular. As noted in the figures, the sole structure 60 has a complete space. Furthermore, the region 71 of the inner surface 60a of the sole structure 60, substantially facing the positive cavities 72 and the negative cavities 74, is substantially flat. Figure 5 In the hot-pressed fabric sole component 70, segment 75 includes a positive cavity 72 and has a thickness e1. Segment 76 of the hot-pressed fabric sole component 70 (without a positive or negative cavity) has a basic thickness e0. Segment 77 of the hot-pressed knitted sole component 70 includes a negative cavity 74 and has a thickness e2. Therefore, the thickness of the hot-pressed sole component 70 is variable, specifically e1 is greater than e2. Figure 6 A variation of an assembly to be heat-pressed to form the upper and sole structure of a shoe is shown. The assembly includes a main fabric lining 80 having an internal space for receiving the foot and comprising one or more at least partially heat-fusible yarns. The main lining 80 includes a sole portion 81, a fore portion 82, a rear portion 83, and an outer portion 84 and an inner portion 85. The assembly also includes a third example of a fabric sole member 90 in the form of a fabric wrap and partially receiving the main lining 80. The fabric sole member 90 includes a sole portion 91 and a peripheral portion 92 for partially wrapping the foot, the peripheral portion 92 extending substantially vertically from the sole portion 91 and extending at least partially along the front and rear edges, as well as the outer and inner edges, of the sole portion 91.

[0178] Another auxiliary sole component, such as a polymer film, can be arranged as an intermediate 95 between the sole portion 81 of the main lining 80 and the sole portion 91 of the fabric sole component 90 to provide reinforcement. Therefore, the components for being hot-pressed to form the sole structure include the fabric sole component 90, the intermediate 95, and at least a portion of the sole portion 81 of the possible lining 80. The components for forming the shoe, including the main lining 80, the fabric sole component 90, and the intermediate 95, undergo a hot-pressing step in which an inflatable bladder is arranged in the internal space of the main lining 80, and the components are then arranged in a mold structure, and the inflatable bladder is inflated to push the outer surface 90b of the fabric sole component 90 into the sole cavity of the mold structure. The components are then heated to a heating temperature Tc to melt a heat-fusible material, particularly at least a portion of the heat-fusible yarn. The hot-melted material fills the sole cavity, thus forming a corresponding at least partially hot-melted fabric sole cavity on the outer surface of the hot-pressed and at least partially hot-melted fabric sole member 90.

[0179] Figure 7 and Figure 8 A second example of a sole structure 100 is shown, which is constructed solely by means of... Figure 6 The fabric sole component 90 shown is obtained by hot pressing. This sole structure 100 is preferably an outsole. The hot-pressed fabric sole component 105 includes a sole portion 106 and a foot wrap portion 108 extending substantially vertically from the sole portion 106. The sole portion 106 has a substantially opposing inner surface 106a and an outer surface 106b. Figure 7 As shown, the inner surface 106a of the sole portion 106 is substantially flat, not noticeable due to the substantially smooth surface of the realized inflatable air bladder. Furthermore, the sole structure 100 includes a positive cavity 110 extending from the outer surface 106b. Advantageously, the sole structure 100 includes an upper 112, a forefoot toe cap 114, and lateral retaining wings 115 via at least partially heat-fused wrapping portions 108.

[0180] Figure 9 An assembly for forming a shoe after at least one hot-pressing step is shown, comprising a second example of a main fabric lining 120 associated with three fabric sole components 130, 132, and 134. The three fabric sole components 130, 132, and 134 are independent and substantially formed together similar to... Figure 6 The fabric envelope 90 is a fabric envelope. Preferably, the main lining 120 and the fabric sole components 130, 132, and 134 each specifically include one or more at least partially heat-fusible yarns.

[0181] Figure 10A third example of an assembly for forming a shoe after at least one hot-pressing step is shown, comprising a main fabric lining 140 associated with two fabric sole components 150 and 152, and an auxiliary fabric lining 160. The two fabric sole components 150 and 152 are independent and are formed substantially together, similar to... Figure 6 The fabric envelope 90 in the middle. Preferably, the auxiliary lining 160, the main lining 140, and the fabric sole components 150, 152 all include one or more at least partially heat-fusible yarns. The two sole components 150, 152 are arranged in each other's extensions and are at least disposed between the sole portion 141 of the main lining 140 and the sole portion 161 of the auxiliary lining 160. In this case, the hot pressing of the components for forming the shoe includes at least partially heat-fusing (especially hot pressing) the main lining 140 and the auxiliary lining 60. The sole structure includes at least a portion of the sole portion 161 of an auxiliary lining 160 that is at least partially heat-melted (especially heat-pressed), fabric sole members 150 and 152 that are at least partially heat-melted (especially heat-pressed), and a sole portion 141 of a main lining 140 that may be at least partially heat-melted (especially heat-pressed). The sole portion of the main lining may be configured (especially during the knitting process to have a significant thickness) for example to include circular stitches and is partially heat-melted, thereby allowing the non-heat-melted yarn pad to remain providing comfort.

[0182] Figure 11 An assembly for forming a shoe after at least one hot-pressing step (iii) is shown, comprising a main fabric lining 170, an auxiliary fabric lining 180, and a fabric sole member 173 with a fabric structure, particularly a knitted structure, uniform with the sole portion 171 of the main lining 170. The assembly may include another fabric sole member with a fabric structure uniform with the sole portion of the auxiliary lining. In this specific example, the sole portion 171 has a fabric structure configured to include at least two thicknesses or fabric layers. The fabric sole member 173 may alternatively be formed from the sole portion 181 of the auxiliary lining 180. In effect, after hot-pressing the assembly, the sole structure comprises at least partially heat-melted and heat-pressed sole portion 181, at least partially heat-melted and heat-pressed fabric sole member 173, and at least partially heat-melted and heat-pressed sole portion 171.

[0183] Figure 12A third example of a sole structure 200 is shown, comprising at least one at least partially heat-fused and heat-pressed fabric sole member 210, comprising: a sole portion 220 having substantially opposing inner surfaces 220a and outer surfaces 220b; and a peripheral portion 230 at least partially heat-fused and heat-pressed for partially wrapping a fabric foot, extending substantially vertically from the sole portion 220 and along a front edge 202, a rear edge 204, a medial edge 206, and a lateral edge 208. The sole structure 200 also includes four lateral branches 240 and four medial branches 250 extending along the peripheral wrapping portion 230 and the lateral and medial edges 208, respectively. Each branch 240 and 250 includes a first end and a second end, the first end being connected to the wrapping portion 230, and the second end being a free end. The second ends of the lateral branches 240 converge toward the second ends of the medial branches 250. In this particular example, the wrapping portion 230 forms a shell that defines a partial receiving space for the foot and includes a rigid toe cap and heel counter. Thus, the sole structure 200 provides reinforcement to the shoe upper via branches 240, 250. The second free ends may also each include through-holes, such as eyelets, for the passage of elongated components such as shoelaces. The sole structure 200 can be obtained by overlapping multiple fabric sole components, wherein at least one fabric sole component has a shape similar to a fabric envelope 90 with outer and inner fabric branches. These branches can be formed in at least one fabric sole component by knitting or cutting. When a shoe is manufactured using at least one fabric lining according to the invention, these branches may be formed due to the localized distribution of heat-fusible yarns on the outer and inner portions of the (primary and / or secondary) lining.

[0184] Figure 13 A first example of a mold structure 300 is shown, which includes an upper left component 310, an upper right component 320, and a lower component 330. The lower component 330 includes components from... Figure 14 Above and Figure 15 The sole cavity 340 is visible from the side. In this example, the sole cavity 340 includes a negative cavity 345, which forms a positive cavity on the outer surface of at least one heat-pressed fabric sole component.

[0185] Typically, the yarns in the above embodiments are as defined herein.

[0186] The method according to the invention advantageously allows for the simplified manufacture of sole structures or shoes comprising upper and sole structures, particularly through a single step of thermoforming and compression molding. The sole structure or shoe can be locally functionalized in a simplified manner without limitation, depending on the configuration and type of yarn used (melting type, color, material, etc.). Furthermore, the entire shoe can be manufactured in a single thermoforming and compression molding step, which greatly simplifies the manufacturing process, reduces costs, and limits waste and errors when numerous operations are required.
