BACKGROUND 1. Field of the DisclosureThe present disclosure relates generally to an article of footwear with breathability and stability structures, including an article of footwear having an upper comprising multi-layered mesh material, and a sole structure that includes breathability structures and stability structures that include a heel plate, a v-shaped outsole, and a thermoplastic polyurethane (TPU) plate.
2. Description of the BackgroundMany conventional shoes or other articles of footwear generally comprise an upper and a sole attached to a lower end of the upper. Conventional shoes further include an internal space, i.e., a void or cavity, which is created by interior surfaces of the upper and sole, that receives a foot of a user before securing the shoe to the foot. The sole is attached to a lower surface or boundary of the upper and is positioned between the upper and the ground. As a result, the sole typically provides stability and cushioning to the user when the shoe is being worn. In some instances, the sole may include multiple components, such as an outsole, a midsole, and an insole. The outsole may provide traction to a bottom surface of the sole, and the midsole may be attached to an inner surface of the outsole, and may provide cushioning or added stability to the sole. For example, a sole may include a particular foam material that may increase stability at one or more desired locations along the sole, or a foam material that may reduce stress or impact energy on the foot or leg when a user is running, walking, or engaged in another activity.
The upper generally extends upward from the sole and defines an interior cavity that completely or partially encases a foot. In most cases, the upper extends over instep and toe regions of the foot, and across medial and lateral sides thereof. Many articles of footwear may also include a tongue that extends across the instep region to bridge a gap between edges of medial and lateral sides of the upper, which define an opening into the cavity. The tongue may also be disposed below a lacing system and between medial and lateral sides of the upper, to allow for adjustment of shoe tightness. The tongue may further be manipulable by a user to permit entry or exit of a foot from the internal space or cavity. In addition, the lacing system may allow a user to adjust certain dimensions of the upper or the sole, thereby allowing the upper to accommodate a wide variety of foot types having varying sizes and shapes.
The upper may comprise a wide variety of materials, which may be chosen based on one or more intended uses of the shoe. The upper may also include portions comprising varying materials specific to a particular area of the upper. For example, added stability may be desirable at a front of the upper or adjacent a heel region so as to provide a higher degree of resistance or rigidity. In contrast, other portions of a shoe may include a soft woven textile to provide an area with stretch-resistance, flexibility, air-permeability, or moisture-wicking properties.
However, while many currently-available shoes have varying features related to the above-noted properties, many shoes have sole structures that suffer from a lack of breathability, as many shoes include unitary sole structures made from Ethylene-vinyl acetate (EVA) or a similar type of material, and such midsoles typically do not include breathable properties. Still further, many athletic shoes, especially running shoes, lack added support structures to aid in stability while running or engaging in strenuous athletic activities.
Therefore, articles of footwear having features that aid in the breathability and stability along both the upper and sole structure thereof are desired. These and other deficiencies with the prior art are outlined in the following disclosure.
SUMMARYA number of advantages of the articles of footwear described herein will be apparent to those having ordinary skill in the art. For example, the various components that comprise the sole can allow for a reduction of weight throughout, which, for running shoes can be a significant benefit. Further, the inclusion of a sole plate within the sole structure described herein can provide a spring-like or trampoline effect, which may provide added benefits to runners that traverse certain types of running surfaces. Still further, the inclusion of a gap underneath the sole plate can enhance the trampoline effect and allow a runner to harness and release more energy while running, which can aid in propelling the runner forward. The various elements and combination of elements within the articles of footwear described herein add varying athletic benefits to the shoe, such as stiffening, spring-like effects, or pronation support.
An article of footwear, as described herein, may have various configurations. The article of footwear may have an upper defining a forefoot region, a midfoot region, and a heel region. The article of footwear further includes a sole structure coupled with the upper, the sole structure comprising a midsole defining a v-shaped notch, an outsole coupled with a bottom surface of the midsole, and a plate that is disposed between the midsole and the upper. The plate is coupled with the midsole in the forefoot region and the heel region, and a gap is formed between the plate and the midsole in the midfoot region. At least one sole aperture is disposed within the sole structure.
In some embodiments, the sole aperture extends through the midsole, the outsole, and the plate. In some embodiments, the article of footwear further includes a mesh disposed over the sole aperture. In some embodiments, the at least one sole aperture comprises a first sole aperture, a second sole aperture, and a third sole aperture. In some embodiments, the first sole aperture is disposed within a forefoot region, the second sole aperture is disposed within a midfoot region, and the third sole aperture is disposed within a heel region. In some embodiments, the plate is relatively thicker within a midfoot region than in a forefoot region thereof. In some embodiments, at least one plate aperture within the plate further defines the at least one sole aperture. In some embodiments, the article of footwear further includes a heel cup disposed at a heel end of the article of footwear.
In some embodiments, an article of footwear includes an upper and a sole structure coupled with the upper. The sole structure includes a midsole, an outsole coupled with a bottom surface of the midsole, and a plate that is disposed between the midsole and the upper. The plate defines a first plate aperture and a second plate aperture.
In some embodiments, the first plate aperture aligns with a first sole aperture, and the second plate aperture aligns with a second sole aperture. In some embodiments, the first sole aperture and the second sole aperture define channels that allow air to flow from an underside of the article of footwear to a foot cavity within the upper. In some embodiments, a gap is formed between the plate and the midsole. In some embodiments, the gap defines a v-shaped notch within the midsole. In some embodiments, the first plate aperture is one of a first plurality of apertures, which are separated by a plurality of first support bars. In some embodiments, the plate comprises TPU.
In some embodiments, an article of footwear includes an upper defining a forefoot region, a midfoot region, and a heel region. The article of footwear further includes a sole structure coupled with the upper, the sole structure comprising a midsole, an outsole coupled with a surface of the midsole, and a plate that is disposed between the midsole and the upper. The plate is coupled with the midsole and a gap is formed between the plate and the midsole. A first sole aperture and a second sole aperture define air channels through the midsole, the outsole, and the plate.
In some embodiments, the plate is thicker within the midfoot region than within the forefoot region. In some embodiments, the article of footwear includes a heel cup disposed at a heel end of the article of footwear. In some embodiments, the heel cup defines lateral and medial legs that are connected with a heel cup arm. In some embodiments, the lateral and medial legs are further connected with a heel bar, which defines a heel cup aperture with the heel cup arm.
Other aspects of the articles of footwear described herein, including features and advantages thereof, will become apparent to one of ordinary skill in the art upon examination of the figures and detailed description herein. Therefore, all such aspects of the articles of footwear are intended to be included in the detailed description and this summary.

In some embodiments, various layers of the upper 42 are heat pressed together so as to bond the various layers of the upper 42. For example, layers that comprise the upper 42 can be heat pressed together all at once and at a single temperature. The upper 42 is further attached to a strobel board 56 (see
With reference to the material(s) that comprise the upper 42, the specific properties that a particular type of yarn will impart to an area of a knitted component may at least partially depend upon the materials that form the various filaments and fibers of the yarn. For example, cotton may provide a soft effect, biodegradability, or a natural aesthetic to a knitted material. Elastane and stretch polyester may each provide a knitted component with a desired elasticity and recovery. Rayon may provide a high luster and moisture absorbent material, wool may provide a material with an increased moisture absorbance, nylon may be a durable material that is abrasion-resistant, and polyester may provide a hydrophobic, durable material.
Other aspects of a knitted component may also be varied to affect the properties of the knitted component and provide desired attributes. For example, a yarn forming a knitted component may include monofilament yarn or multifilament yarn, or the yarn may include filaments that are each formed of two or more different materials. In addition, a knitted component may be formed using a particular knitting process to impart an area of a knitted component with particular properties. Accordingly, both the materials forming the yarn and other aspects of the yarn may be selected to impart a variety of properties to particular areas of the upper 42.
In some embodiments, an elasticity of a knit structure may be measured based on comparing a width or length of the knit structure in a first, non-stretched state to a width or length of the knit structure in a second, stretched state after the knit structure has a force applied to the knit structure in a lateral direction.
In some embodiments, the upper 42 may include additional structural elements, or additional structural elements may surround or be coupled to the upper 42. For example, and referring to

In some instances, the outsole may be defined as a portion of the sole structure that at least partially contacts an exterior surface, e.g., the ground, when the article of footwear is worn. The insole may be defined as a portion of the sole structure that at least partially contacts a user's foot when the article of footwear is worn. Finally, the midsole may be defined as at least a portion of the sole structure that extends between and connects the outsole region with the insole region.
In some embodiments, a sole structure can include one or more sole apertures that extend through the sole structure. For example, referring now to
The plurality of sole apertures 120 include a first or forefoot sole aperture 126, a second or midfoot sole aperture 128, and a third or heel sole aperture 130. The first sole aperture 126 is disposed within the forefoot region 50, the second sole aperture 128 is disposed within the midfoot region 52, and the third sole aperture 130 is disposed within the heel region 54 of the sole 44. Each of the sole apertures 120 is generally triangular in shape, although the sole apertures 120 have varying sizes and orientations. The first sole aperture 126 is the smallest of the plurality of sole apertures 120, and defines a first aperture sidewall 132 that extends from a bottom side 134 of the midsole 108 to a top side 136 thereof (see
While the present embodiment includes triangularly shaped sole apertures 120, varying shapes, such as circles, squares, rectangles, hexagons, octagons, or other types of polygonal shapes are contemplated. Further, the aperture sidewalls 132, 138, 140 each comprise three distinct walls that intersect at rounded and tapered corners; however, depending on the shape of the sole apertures 120, more or fewer walls may define the aperture sidewalls 132, 138, 140.

The midsole 108 is disposed above and exploded from the outsole 106 in
A reinforcing member 180 is further illustrated within the midsole 108, the reinforcing member 180 forming an hourglass shape. The reinforcing member 180 comprises ESS, which is a high durometer EVA, and is co-molded into the midsole 108. The reinforcing member 180 is provided to reduce stress or increase the strength of portions of the midsole 108 that are adjacent the v-shaped notch 160. The reinforcing member 180 may be separately attached via an adhesive to the midsole 108, or may be molded to or within the midsole 108.
Still referring to
In embodiments where the midsole 108 or a portion of the midsole 108 comprises supercritical foam, the supercritical foam may comprise micropore foams or particle foams such as a TPU and EVA mixture or pure PEBAX. The supercritical foam can be manufactured using a process that is performed within an autoclave, an injection molding apparatus, or any sufficiently heated/pressurized container and involves saturating a molten material. The material may include thermoplastic polyurethane, polyolefin elastomers, ethylene-vinyl acetate, or mixtures thereof, with a supercritical fluid that may include supercritical carbon dioxide, supercritical nitrogen, or mixtures thereof. During the process, the solution of supercritical fluid and molten material is pumped into a pressurized container, after which the pressure within the container is released, such that the molecules of the supercritical fluid rapidly convert to gas. This rapid conversion forms small pockets within the molten material and causes the material to expand into a foam, which may be used for the midsole 108. Regardless of the type of material(s) used for the midsole 108, the v-shaped notch 160 is generally formed during the molding process of the midsole 108. In some embodiments, the sole plate 110 comprises TPU while the outsole 106 comprises rubber.
The heel cup 60 is also made of TPU and is glued or stitched to the upper 42 or the midsole 108. The heel cup 60 is disposed at the heel end 62 of the sole structure 44, and is sized and shaped to fit around a heel of a user, externally to the upper 42. The heel cup 60 includes a lateral leg 184 and a medial leg 186 that extend upward and inward to intersect with a heel bar 188 that extends from the lateral leg 184 to the medial leg 186 around the heel end 62. A curvilinear heel arm 190 extends upward from intersections with the lateral leg 184 and the medial leg 186. The heel arm 190 is symmetric and defines an apex 192 at an upper end thereof. The heel arm 190 includes a lateral inflection point 194 and a medial inflection point 196. The heel arm 190 and the heel bar 188 form an aperture 198 therebetween. The heel cup 60 is generally formed to conform to a profile of the heel end of the upper 42 when the shoe 40 is fully assembled. The heel cup 60 further provides added support to a heel of a user when the shoe 40 is being worn. In some embodiments, the heel cup 60 does not include the heel bar 188. In such an embodiment, the heel cup 60 defines an open end with no aperture formed between components.
The heel cup 60 provides additional stability and rigidity for a user when the article of footwear 40 is being worn. The lateral leg 184 and the medial leg 186 in combination with the heel arm 190 allow the heel cup 60 to flex or give as needed when a user is running or engaging in other activities, but otherwise provide more rigid support to the heel of a user. Further, the aperture 198 of the heel cup 60 may become slightly closed or deformed when the arm 190 of the heel cup 60 is deformed downward, which could result when pressure is applied to the apex 192 of the arm 190. The heel bar 188 may also provide additional rigidity to the heel cup 60, which may aid in preventing against undesired flexibility in the heel region 54 when the article of footwear 40 is being worn.

With the gap 162 disposed as shown in the illustrated embodiment, the gap 162 is partly bounded on opposing, e.g., upper and lower, sides by the plate 110 and the reinforcing member 180. Thus, as supported by the plate 110 and the reinforcing member 180, the sole structure 44 can be relatively strong overall, including at the gap 162, while also providing improved flexibility and feel due to the improved flexibility provided at the gap 162.
In some cases, one or more apertures can be aligned with a gap between a plate and a midsole, which may provide improved ventilation of a wearer's foot via the one or more apertures. For example, as shown in

The plate 110 is further shown having varying thickness across the forefoot region 50 and the midfoot region 52, with the plate 110 being thicker along the midfoot region 52 (adjacent the v-shaped notch 160 of the midsole 108), and thinner along the forefoot region 50, which may provide improved support and responsiveness. The front distal end 92 of the plate 110 is spaced inwardly from a toe end 92 of the midfoot region 52. A portion of the heel cup 60 is also shown in cross-section. The plate 110 is sized and shaped to allow for bending into the v-shaped notch 160 of the midsole 108. In some embodiments, various portions of the plate 110 may have the thickness thereof modified to adjust the bending characteristics of the plate 110. In some embodiments, the plate 110 may be customized or modified depending on an intended use of the shoe 40. For example, portions of the plate 110 may be thicker or thinner depending on the type of activity that a wearer of the shoe 40 will undertake.
