[0031] Overview

[0032] Typically, footwear products according to this disclosure include an outsole and one or more traction components incorporated into the outsole. The traction component (also referred to as an insert, a traction-providing insert, or a sole insert) is configured to have one or more properties different from the outsole, such as hardness, color, material type, elasticity, rigidity, resilience, etc. In some examples, the insert provides additional traction between the outsole and an underlying surface (e.g., the ground). Footwear products described herein may include shoes, boots, sandals, and / or any other suitable footwear, or a portion of footwear having an outsole.

[0033] Each traction element includes a protrusion (also called a ground contact element or projection) having a peripheral flange (also called a flange portion) extending from the upper end of the protrusion. The outsole has one or more corresponding openings, each extending through the outsole (i.e., from the top surface of the outsole to the bottom surface). Each traction element is disposed in a corresponding opening in the outsole. In some examples, a given traction element may have multiple protrusions corresponding to multiple openings. For stability and safety, the flange of each traction element is secured or fastened to the top surface of the outsole, while the protrusion extends to or beyond the ground contact surface of the outsole. In some examples, the bottom surface of the protrusion is used to contact the lower surface during use. The bottom surface of the protrusion is used to provide traction between the outsole and the lower surface. In some examples, the bottom surface of the protrusion has a sole pattern and / or sipe pattern.

[0034] In some examples, each opening in the outsole includes a groove located in the outsole and on its top surface, which engages with a hole (also called a aperture) extending to the bottom surface of the outsole (also called the ground contact surface). In some examples, the groove has a different integral shape or planar shape than the hole or aperture. In some examples, the groove and the hole have similar or identical planar shapes. A gripping member is positioned in the opening such that a flange is located in the groove, and a protrusion extends into and through the hole in the ground contact surface of the outsole. In some examples, the flange of the gripping member coincides with the groove of the outsole. In some examples, there is no groove, such that the flange is configured to be located on the top surface of the outsole. In some examples, the hole or aperture through the outsole is laterally surrounded by the outsole.

[0035] In some examples, the bottom surface of the protrusion of the grip member is flush with or substantially coplanar with the ground contact surface of the outsole. In some examples, the bottom surface of the protrusion extends beyond the ground contact surface of the outsole. In some examples, the protrusion extends into a hole such that the bottom surface of the protrusion is relative to a recess in the bottom surface of the outsole. For example, the protrusion may be stiffer than the surrounding outsole and may be configured to contact the lower surface only after the outsole has been compressed.

[0036] The traction components can be positioned relative to the outsole in any suitable location. In some examples, two traction components are located at the front of the outsole, one on the inside and one on the outside. In some examples, two traction components are located at the rear of the outsole, one on the inside and one on the outside. In some examples, the two traction components located at the rear of the outsole or at the heel end form a horseshoe shape. In some examples, the traction components are arranged adjacent to the outer edge of the outsole. In some examples, the protrusions and / or flanges of the traction components are positioned along the adjacent outer contour of the outsole.

[0037] In some examples, the outsole includes a plurality of spaced-apart openings extending from the top surface of the outsole to the ground contact surface. A corresponding individual or separate traction member is disposed within each spaced-apart opening such that each traction member does not contact any other traction member disposed within the other openings. Each of the individual traction members includes a protrusion and a flange extending from the upper end of the protrusion. In some examples, each spaced-apart opening includes a corresponding recess in the top surface of the outsole, spaced apart from the recesses of the other openings. Each spaced-apart recess in the top surface of the outsole communicates with an opening in the ground contact surface of the outsole. In some examples, the flange of each individual traction member is located in a corresponding spaced-apart recess in the top surface of the outsole. In some examples, the flange of each traction member is located in a recess such that the top surface of the flange is flush with the top surface of the outsole.

[0038] A material layer (also called a top-outer layer) is disposed directly over and in direct contact with the top surface of the outsole, and / or disposed directly on and in direct contact with the flanges of each traction member. In some examples, the top-outer layer is disposed over the entire top surface of the outsole, such that the flanges of each traction member are sandwiched between the layer and the top surface of the outsole. In some examples, the top-outer layer is permanently attached to the entire or at least part of the top surface of the outsole. In some examples, the top-outer layer is permanently attached to the top surface of the outsole and the flanges of each traction member. In some examples, the top-outer layer and the outsole are integral. In other words, the top-outer layer and the outsole can be integral and formed as a single piece, such as a single continuous piece. In some examples, the top-outer layer comprises the same material as the outsole. In some examples, the top-outer layer comprises a material with the same stiffness as the outsole.

[0039] In some examples, the flange of each gripping element is sandwiched between the top outer layer and the top surface of the outsole, such that the flange of each gripping element is enclosed within a single outsole comprising the top outer layer. In other words, the flange of each gripping element may be surrounded on each side by the top outer layer and / or the top surface of the outsole. In some examples, the midsole is directly positioned above and in direct contact with the top outer layer. In such examples, the top outer layer provides a surface configured to attach to the midsole. The top outer layer is positioned between the midsole and the top surfaces of the gripping elements and the outsole, separating the midsole from the gripping elements. The midsole may include any suitable midsole configured to provide support and cushioning for the user's foot. The midsole may include a material different from the materials constituting the outsole and the top outer layer of the outsole. For example, the midsole may include a softer material than the materials constituting the outsole and the top outer layer of the outsole. In some examples, the midsole includes EVA foam. In some examples, the insole is directly positioned above and in direct contact with the midsole.

[0040] A method for manufacturing a footwear sole according to this disclosure may include: forming one or more gripping components, forming an outsole, and incorporating the one or more gripping components into the outsole. This method facilitates the production of a variety of different soles with a variety of different properties.

[0041] In some examples, the grip element may be formed separately from the outsole and then inserted and secured to it. Forming the grip element can include compression molding, heated compression molding, injection molding, dual injection molding, additive manufacturing (e.g., 3D printing), and / or any other suitable process. Forming the outsole can include any of the processes listed above for forming the grip element, and / or any other suitable process. In some examples, the grip element is secured to the outsole by adhesive. In some examples, the grip element is secured to the outsole by compression molding, for example, by compression molding the outsole and grip element in the same mold, and / or using any other suitable process. The grip element is secured to the outsole such that it cannot move independently of the outsole.

[0042] In some examples, after the traction member has been inserted into the outsole, a material layer is added on top of the outsole. This material layer covers the traction member, such that the flange of the traction member is sandwiched between the top surface of the outsole and the material layer. In some examples, the material layer comprises the same material as the outsole. The added layer can be compression-molded to or otherwise attached to the outsole and the traction member, such that the material layer forms the top layer of the outsole, and the added layer can comprise the same material as the outsole. In some examples, the material layer is compression-molded to the outsole and the traction member by heating. In some examples, the added layer is attached to the top surface of the outsole, such that the added layer and the outsole are integral and formed as a single piece. In some examples, the midsole is attached to and sits on top of the top layer of the outsole. In such examples, the added layer is positioned between the midsole and the traction member and separates them. In examples without a top layer, the traction member can be sandwiched between the top surfaces of the midsole and the outsole. For example, the flange of the traction member can be in direct contact with both the midsole and the outsole.

[0043] The traction element and / or outsole may include TPU, TPE, blown rubber, high-abrasion rubber, and / or any other suitable material. In some examples, the traction element includes an elastomer. In some examples, the material constituting the traction element is the same as the material constituting the outsole. In some examples, the material constituting the traction element is harder, more flexible, and / or denser than the material constituting the outsole, or the material constituting the outsole is harder, more flexible, and / or denser than the material constituting the traction element. In some examples, the materials constituting the traction element and outsole have different colors and / or translucency. Using materials with different colors and / or translucency to form the traction element and outsole can make the sole more visually appealing. In some examples, the outsole includes a translucent material, and the traction element (e.g., the flange and / or any other suitable portion of the insert) includes a non-translucent material, the color of which is chosen such that the flange of the traction element is visible through the outsole.

[0044] According to the manufacturing method of this disclosure, a variety of shoe soles with different properties can be produced. Changing the materials of the one or more traction components and the outsole will affect the function and visual appearance of the shoe sole. Changing the geometry of the one or more traction components, as well as the position of the one or more traction components within the outsole, will also affect the function and visual appearance of the shoe sole. The manufacturing method of this disclosure facilitates the conversion between manufacturing shoe soles with different properties without changing the apparatus, or with minimal changes to the apparatus.

[0045] Examples, components, and alternatives

[0046] The following sections describe exemplary soles for footwear from selected aspects, as well as related systems and / or methods. The examples in these sections are intended to be illustrative and should not be construed as limiting the scope of this disclosure. Each section may include one or more different embodiments or examples, and / or context or related information, functionality, and / or structure.

[0047] A. Exemplary outsole

[0048] Figures 1-2 An exemplary outsole for footwear, comprising multiple gripping components, is depicted. Figure 1 and Figure 2 The sole of the shoe is an example of the sole described in the overview section above.

[0049] Figure 1 This is a bottom view of the outsole 100. Grip members 102A, 102B, 102C, and 102D are integrated into the outsole 100. Grip member 102A is located in the front outer region, grip member 102B in the front inner region, grip member 102C in the rear outer region, and grip member 102D in the rear inner region of the outsole 100. As described above, the grip members can be positioned relative to the outsole in any other suitable location and orientation, and any suitable number of grip members can be integrated into the outsole. Figure 1 As shown, each gripping element is independent of the other gripping elements and does not contact any other gripping elements.

[0050] Grip members 102A, 102B, 102C, and 102D each have flanges (104A, 104B, 104C, and 104D) and protrusions (105A, 105B, 105C, and 105D). Each of the flanges 104A, 104B, 104C, and 104D is disposed in a corresponding groove in the top surface of the outsole 100. The flanges are attached to the top surface of the outsole, for example, using adhesives, compression molding of the grip members and the outsole (e.g., in the same mold), and / or any other suitable process. In this example, the outsole 100 comprises a translucent material (e.g., translucent rubber), and the flanges 104A, 104B, 104C, and 104D comprise a harder material with a solid color. Therefore, the flanges are visible through the bottom of the outsole or the ground contact surface 112. The outsole and grip members may include any other suitable color combinations and / or combinations of translucency.

[0051] Protrusions 105A, 105B, 105C, and 105D extend into corresponding holes 114A, 114B, 114C, and 114D in the outsole 100. The bottom surfaces of protrusions 116A, 116B, 116C, and 116D have outsole patterns 118A, 118B, 118C, and 118D, which are configured to provide traction with the underlying surface (e.g., the ground, a running track, or a court). The ground contact surface 112 of the outsole also has outsole patterns 120A, 120B, 120C, and 120D. Figure 1 In the examples shown, the outsole pattern of the traction insert has a different orientation and / or pattern relative to the adjacent outsole pattern. For example, the outsole pattern of a traction element may be angled in one direction, while the outsole pattern adjacent to or around it may be angled in another direction. In some examples, the direction of the outsole pattern of a traction element is parallel to the direction of the outsole pattern adjacent to or around it. Typically, traction elements and outsole patterns are used to increase grip, prevent slippage, and / or enhance outsole stability. Any suitable pattern can be used, depending, for example, on the activity or intended type of ground contact surface. The outsole, traction element, or both may be without a outsole pattern. In some examples, the outsole pattern differs from the outsole pattern of the second traction element. In some examples, the outsole pattern is different in different areas of the sole. For example, the outsole pattern may form an alternating pattern on the sole surface, and / or the outsole pattern may gradually change on the sole surface.

[0052] The flanges and protrusions of the gripping components can have any suitable shape and / or size to provide stability, grip, visual appeal, and / or manufacturability. For example... Figure 1 As shown, each of flanges 104A, 104B, 104C, and 104D has a larger planar shape than the corresponding protrusion. In some examples, the flanges and protrusions of the traction element have the same planar shape but different dimensions. In some examples, the flanges and protrusions of the traction element have different planar shapes and different dimensions. Relative to the corresponding protrusion, flanges 104C and 104D extend further toward the toe end of the outsole and form a horseshoe shape at the rear or heel end of the outsole 100. The shape and / or size of the flanges and protrusions can affect the function and appearance of the outsole. The flange of any given traction element may extend around the entire periphery of the protrusion, may extend only partially around the periphery (e.g., only from one side), and / or may not be symmetrical to the shape or position of the protrusion.

[0053] Figure 2This is a top view of the outsole 100. Grip members 102A, 102B, 102C, and 102D are integrated into the outsole 100. A top outer layer 122, comprising the same translucent material as the outsole 100, is disposed on top of the outsole and the grip members. Therefore, flanges 104A, 104B, 104C, and 104D are sandwiched between the top outer layer 122 and the top surface 110 of the outsole 100. As described above, the top outer layer 122 comprises the translucent rubber of the outsole 100. Flanges 104A, 104B, 104C, and 104D are visible through the top outer layer. In some examples, the top outer layer 122 comprises an opaque material and / or a material different from that of the outsole 100. The outsole 100 may be attached to the midsole and / or upper (e.g., as shown below). Figure 3 The above).

[0054] Figure 3 This is a schematic cross-sectional view of another exemplary outsole 200 incorporated into footwear product 201 (i.e., shoe). The cross-section is taken along a line from back to front relative to footwear product 201. Figure 3 Grip members 202A and 202B are depicted, wherein grip member 202A is disposed in the front region of the shoe and grip member 202B is disposed in the rear region of the shoe. Grip members 202A and 202B each include a protrusion (205A and 205B) and a flange (204A and 204B) extending from the upper end (206A and 206B) of the protrusion.

[0055] The horizontal dimensions (e.g., width) of flanges 204A and 204B are greater than those of protrusions 205A and 205B, and the vertical dimensions (e.g., thickness) of flanges 204A and 204B are smaller than those of protrusions 205A and 205B. In some examples, the horizontal and / or vertical dimensions of the flanges and protrusions are the same. In some examples, each gripping member has the same shape, size, and / or planar shape as the other gripping members. In some examples, each gripping member has a shape, size, and / or planar shape that is different from one or more other gripping members.

[0056] Outsole 200 includes openings 207A and 207B extending from top surface 210 of outsole 200 to ground contact surface 212. Openings 207A and 207B each include a recess (208A and 208B) located on top surface 210 of outsole 200, which engages with holes (214A and 214B) extending to ground contact surface 212 of outsole 200. In some examples, the openings do not include recesses.

[0057] Flanges 204A and 204B are located in recesses 208A and 208B. Flanges 204A and 204B completely fill the recesses. In other words, the shape and size of each recess correspond to the corresponding flange. Flanges 204A and 204B are secured to recesses 208A and 208B, thereby preventing the gripping components from moving independently of the outsole. Protrusions 205A and 205B extend into and through holes 214A and 214B. The bottom surface (216A and 216B) of each protrusion is flush with or substantially coplanar with the ground contact surface 212. The bottom surfaces 216A and 216B of the protrusions are configured to provide grip with the underlying surface (e.g., the ground, a track, or a court). A top outer bottom layer 222 is disposed on top of the outsole 200. The top outer bottom layer 222 is disposed over the entire top surface 210 of the outer bottom layer 200, such that flanges 204A and 204B are sandwiched between the top outer bottom layer and the top surface of the outer bottom layer. In some examples, the top outer bottom layer 222 and the top surface 210 of the outer bottom layer 200 are integral and comprise the same material. In some examples, the top outer bottom layer 222 is permanently attached to the top surface 210 and flanges 204A and 204B.

[0058] The outsole 200 and traction components 202A and 202B may comprise any suitable material or combination of materials, such as TPU, TPE, blown rubber, high abrasion rubber, etc. In some examples, the outsole and traction components comprise the same material. In some examples, the outsole and traction components comprise materials with different hardness, ductility, density, color, resilience, elasticity, and / or translucency.

[0059] In this example, the outsole 200 is connected to the midsole 224, and the midsole 224 is connected to the upper 226 to form footwear product 201. Figure 3 As shown, the midsole 224 is attached to the top outsole 222. The top outsole 222 is disposed between the midsole 224 and the top surface 210 and the flanges 204A and 204B of the grip members. The outsole 200 is attached to the midsole 224 by adhesive, co-injection molding and / or any other suitable process. The midsole 224 is attached to the upper 226 by any suitable process known in the art.

[0060] Figure 4This is a schematic cross-sectional view of another outsole 300 incorporated in footwear product 301. A traction member 302A is disposed in the inner region of the outsole, and a traction member 302B is disposed in the outer region of the outsole. Each of the traction members 302A and 302B includes a protrusion (305A and 305B) and has a flange (304A and 304B) extending from the upper end (306A and 306B) of the protrusion. The traction members 302A and 302B are disposed in corresponding openings (307A and 307B) in the outsole 300. Each opening 307A and 307B includes a groove (308A and 308B) in the top surface 310 of the outsole 300. The flanges 304A and 304B are located in the grooves 308A and 308B.

[0061] Flanges 304A and 304B conform to the shape of grooves 308A and 308B. Flanges 304A and 304B are fixed to grooves 308A and 308B. Grooves 308A and 308B are each connected to a corresponding hole (314A and 314B) that extends through the outsole to the ground contact surface 312 of the outsole 300. Protrusions 305A and 305B extend into holes 314A and 314B. Protrusions 305A and 305B each have a bottom surface (316A and 316B) terminating at the ground contact surface 312 of the outsole.

[0062] The outsole 300 is attached to the midsole 324 by an adhesive, by co-molding, and / or any other suitable means or process. In this example and other examples, the midsole 324 may be in direct contact with the top of the grip member (e.g., a flange), such that the flange of the grip member is clamped or otherwise held between the outsole and the midsole.

[0139] B. Exemplary Methods

[0140] See Figure 5 This section describes the steps of an exemplary method of manufacturing a sole for footwear products, having a gripping component incorporated into the outsole. Various aspects of the sole and footwear products described above can be used in the method steps described below. Where appropriate, references may be made to components and systems that can be used to perform each step. These references are for illustrative purposes and are not intended to limit the possible ways in which any particular step of the method can be performed.

[0141] Figure 5This is a flowchart of the steps performed in exemplary method 400, and may not list the complete process or all steps of the method. Although the individual steps of method 400 are described below and in Figure 5 The steps are described, but not all of them need to be performed, and in some cases they can be performed simultaneously or in a different order than that shown.

[0142] Step 401 of method 400 includes forming one or more gripping components, each gripping component including flanges and protrusions, for example, as described above for gripping components 102A-102D. The gripping components can be formed by compression molding, injection molding, dual injection molding, additive manufacturing (e.g., 3D printing), and / or any other suitable process. The gripping components may include TPU, TPE, blow-molded rubber, high-abrasion rubber, elastomers, and / or any other suitable material.

[0143] The flanges and protrusions of each gripping component can have any of a variety of different shapes, sizes, and / or planar shapes. In some examples, the planar shape of the flange differs from that of the protrusion. In some examples, the flange and protrusion have the same planar shape. In some examples, the flange and protrusion have the same horizontal and / or vertical dimensions. In some examples, the width and / or thickness of the protrusion is greater than that of the flange, or the width and / or thickness of the flange is greater than that of the protrusion. The protrusions and flanges of a given gripping component can have different shapes, sizes, and / or planar shapes than the protrusions and flanges of another gripping component.

[0144] In some examples, the bottom surface of each protrusion is used to provide traction. For example, the bottom surface of the protrusion may have a sole pattern including ridges, sipes, grooves, textures, etc. In some examples, the sole pattern is different from the sole pattern of the second traction component. In some examples, the sole pattern is different in different areas of the bottom surface. For example, the sole pattern may form an alternating pattern on the bottom surface, and / or the sole pattern may gradually change on the bottom surface.

[0145] Step 402 of method 400 includes forming an outsole having one or more through-holes. Each opening is used to receive one or more traction elements. The openings can be located in any suitable area of ​​the outsole. In some examples, each opening includes a groove located in the top surface of the outsole, which engages with a hole extending to the ground contact surface of the outsole. The outsole is formed by compression molding, injection molding, dual injection molding, additive manufacturing (e.g., 3D printing), and / or any other suitable process. The outsole includes TPU, TPE, blow-molded rubber, high-abrasion rubber, and / or any other suitable material. In some examples, the outsole includes a translucent material. In some examples, the outsole includes the same material as the traction elements. In some examples, the outsole includes a material with a different color, degree of translucency, density, ductility, and / or hardness than the material constituting the traction elements.

[0146] Step 403 of method 400 includes inserting each gripping member into the outsole. Each gripping member is inserted into a corresponding opening in the outsole. In some examples, the gripping member is inserted such that a flange is located in a corresponding groove in the top surface of the outsole. In some examples, the shape and / or curvature of the flange matches that of the groove. In some examples, there is no groove in the opening, and the gripping member is inserted such that the flange is located on the top surface of the outsole. In some examples, a protrusion of the gripping member extends into the hole such that the bottom surface of the protrusion is coplanar with the ground contact surface of the outsole. In some examples, the protrusion extends into the hole and beyond the ground contact surface of the outsole.

[0147] Step 404 of method 400 includes securing and / or fastening each grip element to the outsole. A flange is secured to the outsole to ensure safety and stability. In some examples, the flange of each grip element is secured to the top surface of the outsole. In some examples, the flange of each grip element is secured to a corresponding groove in the top surface of the outsole, and the flange is located in the groove. The flange of each grip element is secured to the top surface of the outsole and / or the groove in the top surface of the outsole using an adhesive, compression molding of the grip element and the outsole in the same mold, compression molding using heat, and / or any other suitable process. The flange of each grip element is secured to the outsole to prevent the grip element from moving independently of the outsole. In some examples, securing each grip element in step 404 includes clamping the flange of the grip element between the outsole (e.g., a groove in the outsole) and a top material layer. For example, a thin layer (e.g., having the same material as the outsole) may be secured and / or molded on top of the outsole and the insert.

[0148] In some examples, steps 401 to 404 are performed simultaneously, causing the gripping element to be firmly formed in the opening of the outsole.
