Claims (20)

1. 1. An article of footwear, comprising: An outsole having a plurality of spaced apart openings, wherein each of the openings extends from a top surface of the outsole to a ground-contacting surface of the outsole; a respective independent ground gripping member disposed within each opening of the outsole, each ground gripping member including a projection and a flange portion extending from an upper end of the projection and secured to the top surface of the outsole; a first sole pattern formed on a bottom surface of the protrusion of each ground gripping member, and having a first overall orientation; A second sole pattern formed on the ground-contacting surface of the outsole adjacent to the protrusion of each ground-engaging member, wherein the second sole pattern has a second overall orientation that is different from the first overall orientation; A layer of material permanently attached to at least a portion of the top surface of the outsole such that a respective flange portion of each traction member is sandwiched between the layer of material and the top surface of the outsole, an The midsole is directly arranged above the material layer and is in direct contact with the material layer.
2. 2. The article of footwear of claim 1, wherein the opening includes a groove in the top surface of the outsole, the groove in communication with a hole in the ground-contacting surface, wherein the groove is larger in size than the hole.
3. 3. The article of footwear of claim 2, wherein the flange portion of the ground engaging member conforms to the shape of the groove.
4. 4. The article of footwear of claim 1, wherein the ground gripping member comprises a first material and the outsole comprises a second material.
5. 5. The article of footwear of claim 4, wherein the first material and the second material each have a different hardness.
6. 6. The article of footwear of claim 1, wherein the projection includes a bottom surface having a tread pattern along a first direction and a portion of the ground-contacting surface of the outsole includes a tread pattern along a second direction.
7. 7. The article of footwear of claim 1, wherein the ground engaging member comprises an elastomer.
8. 8. The article of footwear of claim 1, wherein the outsole comprises translucent rubber.
9. 9. The article of footwear of claim 1, wherein the flange is secured to the top surface of the outsole by an adhesive.
10. 10. The article of footwear of claim 1, wherein the layer of material comprises the same material as the outsole.
11. 11. The article of footwear of claim 1, wherein the layer of material is disposed over the entire top surface of the outsole.
12. 12. The article of footwear of claim 1, wherein the layer of material is permanently attached to the top surface of the outsole and the flange portion of each ground-gripping member.
13. 13. The article of footwear of claim 1, wherein the material layer and the outsole are unitary.
14. 14. A method of manufacturing an article of footwear, the method comprising: forming a ground gripping member including a flange portion and a protruding portion; Inserting the protrusions of the ground engaging members into openings in an outsole, the openings extending from a top surface of the outsole to a ground-contacting surface of the outsole, and Securing said flange portion to said top surface of said outsole, Wherein the footwear is the footwear of claim 1.
15. 15. The method of claim 14, wherein forming the outsole comprises compression molding.
16. 16. The method of claim 14, wherein the opening comprises a groove in the top surface of the outsole, the groove in communication with a hole in the ground-contacting surface, wherein the groove is larger in size than the hole.
17. 17. The method of claim 16, wherein the groove has a different planar shape than the hole.
18. 18. The method of claim 16, wherein the flange portion is flush with the top surface of the outsole when the ground-gripping member is inserted.
19. 19. The method of claim 14, wherein the protrusion has a sole pattern, wherein the sole pattern is different from a second sole pattern of the outsole.
20. 20. The method of claim 14, wherein forming the outsole includes forming the outsole in a first mold and forming the traction member includes forming the traction member in a second mold.

Description

Outsole with traction inserts Technical Field The present disclosure relates to systems and methods for footwear. More particularly, the disclosed embodiments relate to outsoles and related methods of manufacture. Background Footwear products, such as soles of athletic shoes, typically provide support for the foot of the wearer and traction between the footwear product and an underlying surface (e.g., a ground or court surface). Wearing footwear having soles that provide a high level of traction may improve footwear performance and comfort. Disclosure of Invention The present disclosure provides systems, devices, and methods related to footwear outsoles. In some embodiments, an article of footwear includes an outsole having an opening extending from a top surface of the outsole to a ground-contacting surface of the outsole, a ground-engaging member disposed within the opening of the outsole, the ground-engaging member including a protruding portion and a flange portion extending from an upper end of the protruding portion and secured to the top surface of the outsole. In some embodiments, a method of manufacturing an article of footwear includes forming a traction member including a flange portion and a protrusion, inserting the protrusion of the traction member into an opening in the outsole, the opening extending from a top surface of the outsole to a ground-contacting surface of the outsole, and securing the flange portion to the top surface of the outsole. The features, functions, and advantages can be achieved independently in various embodiments of the present disclosure or may be combined in yet other embodiments in which further details can be seen with reference to the following description and drawings. Drawings FIG. 1 is a bottom view of an exemplary outsole according to the present disclosure. Fig. 2 is a top view of the outsole of fig. 1. FIG. 3 is a cross-sectional schematic diagram depicting an exemplary article of footwear having an outsole in accordance with aspects of the disclosure. FIG. 4 is a cross-sectional view of another example sole of the article of footwear along line 4-4 of FIG. 1. FIG. 5 is a flow chart depicting steps of an exemplary outsole manufacturing method in accordance with aspects of the present disclosure. Detailed Description Various aspects and examples of footwear outsoles having inserts for providing traction, and associated methods of manufacture, are described below and illustrated in the associated figures. Unless otherwise indicated, soles and/or various components thereof according to the present disclosure may comprise at least one of the structures, components, functions, and/or variations described, illustrated, and/or incorporated herein. Furthermore, unless specifically excluded, process steps, structures, components, functions, and/or variations described, illustrated, and/or incorporated in connection with the present disclosure herein may be included in other similar devices and methods, including those that are interchangeable between disclosed embodiments. The following description of the various examples is merely exemplary in nature and is in no way intended to limit the disclosure, its application, or uses. Furthermore, the advantages provided by the examples and embodiments described below are exemplary in nature and not all examples and embodiments provide the same advantages or the same degree of advantages. The detailed description includes the following sections (1) definitions, (2) summaries, (3) examples, components and alternatives, (4) advantages, features and benefits, and (5) conclusions. Examples, components, and alternatives are further divided into multiple subsections, each subsection having a corresponding label. Definition of the definition Unless otherwise indicated, the following definitions apply herein. "Comprising," including, "and" having (and variations thereof) are used interchangeably to mean including, but not limited to, and are open-ended terms that are not intended to exclude additional, unrecited elements or method steps. Terms such as "first," "second," and "third" are used to distinguish or identify various components of a group, etc., and are not intended to represent a sequence or a number limitation.
