REFERENCE TO RELATED APPLICATIONS This U.S. Non-Provisional Patent Application claims the benefit of priority from U.S. Provisional Patent Application Ser. No. 63/213,565, filed Jun. 22, 2021, and U.S. Provisional Patent Application Ser. No. 63/192,428, filed May 24, 2021, the entire disclosures of which are hereby incorporated by reference.
FIELD The present disclosure relates generally to footwear. More specifically, embodiments of the present disclosure relate to shoes including cycling shoes. Footwear articles with various structures are provided herein. Articles and features for footwear are provided herein to increase structural integrity of at least certain portions of footwear and to enable the use and provision of various materials for construction of the articles.
BACKGROUND The earliest known footwear articles are believed to date back to 7,000 or 8,000 B.C. Over millennia, various improvements to shoes and footwear articles have been developed. Shoes and footwear have been refined for various specialized applications including, for example, cycling. While conventional flat bicycle pedals may accommodate various different types of footwear, “clipless” pedals generally require a particular type of shoe that includes a cleat for interfacing with a pedal, as well as various features for obtaining stiffness and increasing handling and power transfer from a rider to a bicycle. An example of an existing cycling shoe is shown and described in U.S. Pat. No. 5,406,723 to Okajima which is hereby incorporated by reference in its entirety.
In addition to overall comfort and support, stiffness is often a critical consideration in cycling shoes. Cycling shoes provide a primary touch point between a user and a bicycle and provide an interface and power transmission point between the rider and machine. Generally speaking, stiffer shoes provide a better connection with a machine, minimize power transmission losses, and improve overall speed and handling. Cycling shoe systems of the prior art, however, generally rely on material selection to increase stiffness. Many cycling shoes are now known to incorporate carbon-fiber into the sole and other areas to increase stiffness and decrease weight. Various plastics, hydro-carbon derived materials, and other toxic or non-biodegradable materials may be provided in certain areas of known cycling footwear articles. These materials are generally selected in the interest of maximizing stiffness or strength while reducing weight and cost, and with little regard for environmental impacts.
SUMMARY Accordingly, there has been a long-felt but unmet need to provide footwear articles including non-toxic, natural, environmentally friendly, and/or biodegradable materials, and preferably compostable (at least through commercial composting facilities), and wherein the articles include desired or required structural features. In some embodiments, cycling shoes are provided including a particular structure that enables sufficient structural integrity even when fabricated from plant-based and/or biodegradable materials. The present disclosure provides for methods, systems, and devices for footwear articles.
In one embodiment, a footwear article is provided that includes a footwear upper including a knit fabric, a heel counter, a footbed, and a lasting board, wherein at least one of the heel counter and the lasting board includes a plurality of stacked wood layers and wherein at least two adjacent wood layers include non-parallel grain directions.
It is an object of the present disclosure to provide footwear systems that reduce environmental impacts while still achieving the required strength and stiffness for cycling shoes. In some embodiments, systems are provided wherein footwear articles and all associated packaging includes non-toxic, natural, biodegradable, and/or environmentally-friendly materials, and preferably compostable (at least through commercial composting facilities) materials.
In some embodiments, footwear articles are provided that provide a combination of stiffness and support suitable for cycling while also providing flexibility and flexure to facilitate various off-bike activities including but not limited to walking. For example, a lasting board of the footwear articles are contemplated as including areas capable of interfacing with cleats for a clipless pedal system. By way of another example, the lasting board of the footwear articles are contemplated as including varying thicknesses caused by an increased or reduced number of layers throughout a lasting board of the footwear articles. In other embodiments, the lasting board of the footwear articles comprises one or more notches for increased flexibility.
In one particular embodiment, a footwear articles comprises a lasting board, a heel counter, and a footwear upper. The heel counter is configured to couple to the lasting board by inserting a portion of the heel counter into the lasting board. The footwear upper comprises a knit fabric, and is configured to couple to at least one of the heel counter and the lasting board. At least one of the heel counter and the lasting board comprises a plurality of stacked wood layers. At least two adjacent wood layers comprises non-parallel grain directions.
In some embodiments, at least one metal or fabric layer is inserted between adjacent wood layers of the plurality of stacked wood layers. In some embodiments, at least one of the heel counter and the lasting board comprises at least one fabric layer surrounding the plurality of stacked wood layers.
In some embodiments, at least an inner portion of the lasting board includes a support positioned in a toe region. In additional embodiments, the lasting board includes a void positioned proximate to the support in the toe region. In additional embodiments, the lasting board includes at least one location where a first subset of the plurality of stacked wood layers is differently dimensioned from a second subset of the plurality of stacked wood layers. A thickness of the lasting board is decreased and a flexibility of the lasting board is increased at the location due to the different dimensioning. In additional embodiments, the first subset of the plurality of stacked wood layers are dimensioned to include the support positioned in the toe region. The second subset of the plurality of stacked wood layers is differently dimensioned and does not include the support positioned in the toe region.
In some embodiments, the lasting board includes at least one notch positioned proximate to a toe region. The notch increases flexibility of the lasting board proximate to the toe region. In some embodiments, the footwear upper, the heel counter, the footbed, and the lasting board of the footwear article is biodegradable and compostable.
In some embodiments, the article comprises at least one aperture for a cycling cleat. In additional embodiments, the at least one aperture is a female threaded aperture for receiving a fastener for the cycling cleat. In additional embodiments, the at least one aperture includes one or more slots for receiving the cycling cleat or cleat hardware configured to couple to the cycling cleat.
In another particular embodiment, a method of forming a footwear article includes, but is not limited to, forming a footwear upper of the footwear article from a knit fabric, forming at least one of a heel counter and a lasting board for the footwear article from a plurality of stacked wood layers by laminating the plurality of stacked wood layers, where at least two adjacent wood layers comprise non-parallel grain directions, coupling the heel counter and the lasting board by inserting a portion of the heel counter into the lasting board, and coupling the footwear upper to at least one of the heel counter and the lasting board.

As shown, the heel counter 120b includes a closed bottom portion 152. The heel counter 120b connects to a lasting board 118 and provides stability and stiffness to an assembled footwear article. As shown in FIG. 15D, the heel counter 120b is sandwiched between a heel portion of the lasting board 118 and the lasting board 118 and a heel cushion 119. Alternative arrangement and layering, however, are contemplated. In some embodiments, for example, it is contemplated that a portion of the heel counter 120 is layered between the outsole and the lasting board. In some embodiments, the outsole conforms to and is secured to at least a portion of the heel counter 120b.
FIGS. 16A-16C provide various views and details of a lasting board 118 according to embodiments of the present disclosure. As shown in FIG. 16A, a lasting board is provided that includes a layered or laminated structure and which preferably includes sustainable materials including but not limited to biodegradable and/or recyclable materials. The lasting board 118 includes a heel portion 122, an arch portion 124, and flanges 154 to provide support. The lasting board 118 preferably includes a plurality of layers including, for example, a wood layer 156 (e.g., a top lightweight wood layer), a fabric layer 157 (e.g., allowing for flexibility in the forefoot of the plate), a second wood layer 158 (e.g., a bottom layer adding strength), and printing or decoration (e.g., applied with soy based inks, milk based paint, laser etching, branding or burning, embossing (pressing during molding), or foil transfer) on one or more of the layers A-C. FIG. 16B shows the lasting board 118 in an elevation view.
FIG. 16C provides additional details on the construction and components of the lasting board 118. As shown in FIG. 16C, the lasting board 118 includes a plurality of layers 156, 157, 158.

First layer 156, second layer 157, and third layer 158 are contemplated as being secured together to form a layered lasting board 118. The lasting board 118 is the backbone. Added sections or layers within the lasting board 118 allows for the lasting board 118 to be rigid in some areas and flexible in others, which is important because the lasting board 118 is intended for flexibility when walking but also to be rigid while pushing down on a pedal for cycling.
FIGS. 17A-17B provides plan views of a plurality of different lasting boards 118 (1, 2, 3, 4) according to embodiments of the present disclosure. The lasting boards of FIG. 17A-17B are contemplated as including lasting boards for footwear articles that are not intended to receive a cleat for a clipless cycling pedal system. The embodiments of FIG. 17A-17B are contemplated as being suitable for use with flat pedal systems (for example) as well as various non-cycling related activities including but not limited to walking. The lasting boards are contemplated as including at least one and preferably a plurality of slots 130 for allowing the lasting board to flex or bend while walking (while off the bike, for example). The lasting boards are further contemplated as including various cut-outs and voids to allow flexure of the system. FIG. 17B depicts a lasting board 118 (e.g., 4) according to embodiments of the present disclosure. As shown, the lasting board 118 includes support 160 along the majority of an inner portion of the lasting board 118. A void space 162 within or proximate to the inner portion is provided to reduce overall stiffness and allow for flexure and comfort while engaging in non-cycling activities.
FIGS. 18A-18B provide plan views of a plurality of different lasting boards 118 (1a, 2a, 3a, 4a) according to embodiments of the present disclosure. The lasting boards of FIG. 18A-18B are contemplated as including lasting boards for footwear articles that are intended to receive a cleat for a clipless cycling pedal system, as well as various non-cycling related activities including but not limited to walking. The lasting boards are contemplated as including at least one and preferably a plurality of slots 130 for allowing the lasting board to flex or bend while walking (while off the bike, for example). The lasting boards are further contemplated as including various cut-outs and voids to allow flexure of the system. As shown, the lasting boards 118 of the embodiments of FIG. 18A-18B include a cut-out or recess 164 for receiving additional components including, for example, cleat for cycling pedals. FIGS. 18A-18B generally illustrate and contemplate the ability to accommodate a SHIMANO SPD™ cleat. It will be recognized, however, that the present disclosure and the embodiments shown and discussed herein are not limited to any particular pedal or cleat system.
FIG. 19A is a perspective view of a lasting board 118 according to embodiments of the present disclosure, with cross section view A-A. For example, FIG. 19A illustrates the embodiment of the lasting board 118 of FIG. 18B. FIG. 19B is an exploded cross-sectional view of the lasting board 118 taken at the indicated cross section line G-G of FIG. 19A, with top layer 156, middle layer or fabric/flexible layer 157, and bottom layer 158. The lasting board 118 is contemplated as including a plurality of laminated layers 156, 157, 158 with void spaces for receiving cleat hardware 166 including (for example) bolts and female threaded apertures for selectively securing a cleat to the article of footwear.
FIG. 20A is an exploded perspective view of a lasting board 118, with cross section line H-H. In FIG. 20A, the lasting board 118 includes six layers, with rigid or semi-rigid layers 170, 172, 174, 176 positioned between fabric/flexible layers 168 and 178. For example, in some embodiments the layers 168 and/or 178 are fabricated from a silk or woven fabric, while one or more of the layers 170, 172, 174, 176 are fabricated from a wood layer (e.g., wood veneer). FIG. 20B is an expanded view of the layers 168, 170, 172, 174, 176, 178 of the lasting board 118 in FIG. 20A. FIG. 20C is a cross section view at line H-H of the lasting board 118 of FIG. 20A.
In one example embodiment, the layers 170, 172, 174, 176 is laminated micro-veneer layers, which are stacked and pressed together to create a structure. In preferred embodiments, the micro-veneer layers include wood layers with a specific fiber direction. A “lay-up” is provided that preferably includes alternating the directions of the grain in each layer. The plurality of grain directions and layering of the same provides enhanced structural integrity for the resulting structure. Additionally, the layers are shown as footpad shapes in FIG. 20A-20C but are contemplated as being formed and pressed in various shapes including, for example, a tub-shaped heel counter shape. Ribs (not shown in FIGS. 20A and 20C) are contemplated as being provided to increase strength.
As illustrated in FIG. 20A-20C, a first subset of layers is different in dimension than a second subset of layers. For example, at least one of the layers 170, 172, 174, 176 is contemplated as comprising a difference in dimension (e.g., shorter, and the like) compared to the other layers. For instance, the lasting board 118 is contemplated as comprising layers 168, 170, 172, 174, and 178 which are dimensioned to provide support 160 along an inner portion proximate to the toe region, and a void 162 for the remainder of the toe region. In addition, the lasting board 118 is contemplated as comprising a layer 176 which provides no support 160 to the toe region, such that the layer 176 is truncated or shorter in total length than the layers 168, 170, 172, 174, and 178. This difference in dimension may allow for focusing of rigidity, flexibility, and/or application of force within the lasting board 118, while reducing a thickness of the lasting board 118 at the location of the different dimensions. For example, shorting the layer 176 as illustrated in FIGS. 20A-20C proximate to the toe region of the lasting board 118 reduces the thickness in the toe region, and allow for a more flexible toe region, while retaining a desired stiffness in the ball, arch, and heel regions of the lasting board 118.
Where a layer 176 is truncated or shorter than other layers, the layer 176 includes an edge 173.
In one example embodiment, the edge 173 is dimensioned to be constant in distance from the heel region, relative to a longitudinal axis through the lasting board 118, where the longitudinal axis is defined along a central or bisecting axis from the heel region to the toe region of the lasting board 118. For example, the layer 176 may include a lateral edge 173 that is perpendicular or substantially perpendicular to the longitudinal axis through the lasting board 118. By way of another example, the layer 176 may include an edge 173 that is contoured to conform to a ball of user's foot. For example, contouring to conform to the user's foot may set the lateral edge 173 at a non-perpendicular angle to the longitudinal axis through the lasting board 118. It is contemplated this configuration provides flexibility in the toe region of the user's foot such as when walking due to the layer 176 being absent, while providing additional rigidity to the remainder of the lasting board 118 (e.g., in the region of the sole and the heel) due to the additional layer 176 being present.
In another example embodiment, the edge 173 includes a middle point 175 proximate to the toe region which is greater in distance from the heel region than the distances of points 177 along the outer edges 179 of the lasting board 118 from the heel region, relative to the longitudinal axis through the lasting board 118. For example, the middle point 175 may be set on the longitudinal axis of the lasting board 118 and proximate to the toe region. By way of another example, the middle point 175 may be offset from the longitudinal axis of the lasting board 118 (e.g., between the longitudinal axis and the support 160 of the lasting board 118) and proximate to the toe region. It is contemplated this configuration provides increased rigidity along a spine of the lasting board 118, as the middle point 175 may be increased in distance from the heel region as compared to where the edge 173 is constant in distance along its lateral length relative to the heel region. In addition, it is noted this configuration also allows for increased flexibility in the toe region (e.g., including proximate to the support 160), as the points 177 on the outer edges 179 of the lasting board 118 may be decreased in distance from the heel region as compared to where the edge 173 is constant in distance along its lateral length relative to the heel region.
It is noted the above example embodiments are not limited to the layer 176, and that any layer or layers of the lasting board 118 may be truncated or shorter without departing from the scope of the present disclosure.
It is noted the flexible layer 178 may contact the layer 176 along a first portion of the lasting board 118 and may contact the layer 174 along a second portion of the lasting board 118, due to the difference in dimension (e.g., length, and the like) of the layer 176. In addition, it is noted the fabric layers 168 and 178 contemplated as protecting the inner wood support layers 170, 172, 174, 176, while also increasing comfort of the lasting board 118.
Although FIGS. 20A-20C include layers 168, 170, 172, 174, 176, 178, it is contemplated that the lasting board 118 in FIGS. 20A-20C includes more or fewer layers than those depicted and described, without departing from the present disclosure.
As illustrated in at least FIGS. 20A-20C, the layers 168, 170, 172, 174, 176, 178 is contemplated as being pre-cut and then laminated or otherwise adhered together. In an alternative embodiment, FIG. 21A illustrates a laminated stack 180 of material and FIG. 21B illustrates a lasting board 118 cut from the laminated stack 180. In this embodiment, layers of a lasting board 118 are stacked, laminated, or otherwise adhered, and then cut to the desired dimensions. This embodiment reduces the possibility of a miscut between layers, such that the layers of the lasting board 118 do not align when stacked together for lamination. It is noted this arrangement still allows for the focusing of rigidity, flexibility, and/or general application of force within the lasting board 118 as any layer with different dimensions is capable of being formed prior to arrangement in the stack, as illustrated in FIGS. 21A and 21B with the difference is color variations representing different dimensioned layers.
It should be understood the lasting board in FIGS. 20A-21B are capable of including a cut-out or recess 164 to receive cleat hardware 166 as illustrated in FIGS. 18A-19B, without departing from the scope of the present disclosure.
Various embodiments of the present disclosure including but not limited to those shown in FIGS. 1A-21B provide footwear articles and related features. The articles and related features, components, etc. are contemplated as including one or more sustainable materials such as compostable, biodegradable, recycled, recyclable, and reusable materials. In some embodiments, for example, articles are provided that are devoid of material that is not accepted by a commercial composting facility.
