The present description relates, in general, to footwear and its manufacture. More particularly, the present description relates to footwear in the form of a slide-type shoe (or “slide”) that is designed in a unique manner to facilitate local assembly and customization and also for adjustability in fit by the end user or wearer of the footwear.
There are many situations in the footwear industry in which it is desirable to provide footwear, such as a slide-type shoe (or, more simply, “a slide”), that is designed to allow an end user or purchaser to be able to adjust its fit or size. This is useful so that footwear or slides with such an adjustable design can be worn by people with a range of shoe sizes but yet provide a comfortable fit while also being tight or snug enough that they remain on the wearer's feet during walking. Also, such a design simplifies manufacture as it avoids the requirement of manufacturing a different article of footwear for each shoe size of a targeted customer pool.
Further, though, there is a demand for footwear, including slides, that is designed to be assembled in the country in which it will later be sold. This is desirable for a number of reasons including marketing as “Made in This Country” as well as to reduce tariffs or duties in many cases.
Still further, many in the footwear industry are demanding footwear designs that are customized for a particular set of customers. For example, it is often desirable for clothing and footwear to be designed to show a wearer's support of a particular university or for a particular sporting team. As another example, a business such as a golf course or a destination resort may wish to sell clothing and footwear that allows purchasers and wearers to show that they are loyal to that business or that they played golf a that course or stayed at that resort.
To date, there has not been a footwear design (such as a design for a slide) that successfully meets all three of these design goals. As a result, there remains a need for a new footwear design that provides footwear or a slide that is adjustable by the end-user or wearer, that is configured to be locally assembled in the country or region of sale and/or distribution, and that is also adapted to be customizable such as with a color(s), a logo(s), and/or a branding component(s) during assembly before sale/distribution or even by the end user or customer after purchase.
Briefly, a new design is provided by the inventor for footwear or a slide that is specially adapted for local assembly. The slide is designed to be made up of several parts or components, and all (or a subset) of these may be manufactured by one or more manufacturers and provided to another party for assembly in a location that is “local” to a point of sale (e.g., components made in one or two countries and then shipped to another country for assembly). The assembly of the separate or modular parts or components produces a slide (or slide assembly or footwear assembly, herein) that is suitable for sale and for wear by the purchaser or end user.
One or more of the parts or components provided to the assembling party may be provided in the form of a blank that can be modified to provide local customization while other embodiments will utilize or include a customized part or component manufactured locally for later assembly with the parts or components that were not made locally. Further, the new design for slides includes one or more features that allow the end user or wearer to adjust the size and/or fit of each slide to suit the size and shape of their foot.
More particularly, a footwear assembly is provided that is configured for local assembly, customization, and adjustability in size and fit. The assembly includes a midsole and a top strap with an elongated planar body. The assembly also includes an attachment system including a first attachment element supported at a first location on a side of the midsole, a second attachment element supported at a second location on the side of the midsole opposite the first location, a third attachment element provided on an inner surface of the body of the top strap near a first end, and a fourth attachment element provided on the inner surface of the body of the top strap near a second end opposite the first end. A functional piece of footwear is assembled by first coupling the first and third attachment elements together and by second coupling the second and fourth attachment elements together to detachably mount the first and second ends of the body of the top strap to the side of the midsole.
In some implementations, the attachment system includes one of a hook and loop system, snap buttons, one or more magnets and matching ferrous elements, and one or more buckles. Then, the first and third attachment elements and the second and four attachment elements each include differing halves of detachable coupling pairs of the one of the hook and loop system, the snap buttons, the one or more magnets and matching ferrous elements, and the one or more buckles. Further, in some cases, the first and third attachment elements and the second and third attachment elements are configured such that at least one of the detachable coupling pairs is adapted for coupling in two or more positions, whereby a size or a fit of the functional piece of footwear can be set at two or more states.
In these or other implementations of the footwear assembly, the body of the top strap is formed of a flexible material, whereby the body is elastically deformable during assembly of the functional piece of footwear. In such cases, the flexible material is selected from the group consisting of leather, polyurethane, nylon, silicon, rubber, and plastic or other synthetic material. The outer surface of the top strap may include at least one customization element to allow local or end user customizing of the footwear assembly. For comfort, the assembly may further include a liner comprising a compressible and/or elastic body mounted on the inner surface of the body of the top strap.
Briefly, embodiments described herein are directed toward footwear, such as a slide (or a footwear assembly or slide assembly), that is configured for local assembly. In this regard, all or portions of the footwear may be manufactured by a first manufacturer and then shipped to another party located in another geographic region or country for local assembly into the footwear that is suitable for sale and use by an end user or wearer. The first manufacturer may provide one or more parts for the final footwear assembly in the form of a blank that can be modified to provide local customization of the footwear. In other embodiments of the present description, the customized component(s) of the footwear assembly is manufactured locally (i.e., in same geographic region or country as the assembling party) by the assembling party or another manufacturer and provided to the assembling party. Further, the new footwear is designed with one or more features that allow its size and/or fit to be adjustable by the end user or wearer.
The midsole and outsole assembly includes an outsole 112, which often will be made of a more durable and hard material such as a plastic or hard rubber, and a midsole 114, which may be formed of a material that is softer to be more cushioning such as a compression EVA, a polyurethane (e.g., made via PU injection techniques), cork, and/or synthetic materials. A bottom surface 116 of the midsole 114 is affixed (e.g., via an adhesive or other technique) to the outsole 112 to form the midsole and outsole assembly or base of the footwear assembly or slide 100.
In the midsole and outsole assembly, a pair of wing liners or wings 120, 124 are attached at opposite locations to the side 118 of the midsole 114 (e.g., about halfway along the length of the midsole 114 on left and right edges). The two wing liners (or left and right wings) 120, 124 have bodies (with a width of 1 to 4 inches or the like and a length of 3 to 6 inches or the like) extending, respectfully, from an upper end (see upper end 123 of liner 120) to a lower end 122, 126, which is affixed to the side 118 of the midsole 114. The bodies of the wing liners 120, 124 have an outer surface 121 and 125 that faces away from the midsole 114 upon assembly as shown with arrows 128 and 129. The wing liners 120, 124 may be formed of one or more materials (neoprene, a textile, leather, a synthetic material, and so on) that are chosen such that the wing liners 120, 124 are flexible and soft.
Each wing liner is attached (e.g., via adhesive, stitching, and/or the like) at an outer or lower end 122, 126 to an outer edge or side 118 of the midsole 114. For example, the liners 120, 124 may each be attached, as shown, at a center location along the midsole length or at a location that is some distance forward from center. An inner or upper end (such as end 123 of wing liner 120) is left unattached or free to be moved during assembly shown by arrows 128 and 129. During assembly, the two inner or upper ends of the wing liners 120, 124 are moved into an overlapping position to form (as shown with arrow 150) an assembled midsole and outsole assembly as seen in
A stretch webbing (e.g., a nylon strip extending across one of the wings upper or lower surfaces) or other alignment element 140 is provided on the upper or outer surface 125 of one of the wing liners 124 to keep the two overlapping wings 120, 124 as shown in
The footwear assembly 100 is finally assembled 190 or becomes an assembled system as shown in
To apply the top strap insert 160 on the wing liners 120, 124, an attachment system is included in the footwear assembly 100. This attachment system includes a pair of wing components or elements (or attachment element A and attachment element B) 132, 130 affixed to the outer or lower ends 122, 126 and on the outer or uppers surface 121, 125 of the wing liners 120, 124. The attachment system further includes a corresponding pair of components or elements (or attachment element C and attachment element D) 172, 170 mounted or provided on an inner or lower surface 164 (at outer edges or ends so as to be in mating position with elements 132, 130) of the body of the top strap insert 160.
The attachment system may be provided in a wide variety of manners that allows for the two outer ends of the top strap insert's body to be attached to, and later detached from, the lower or outer ends of the two wing liners as shown in
This configuration of the midsole and outsole assembly combined with the top strap insert 160 facilitates or enables local assembly of the footwear assembly or slide 100 (e.g., to achieve an assembled system or piece of footwear such as a slide where each of the separate components do not provide functioning footwear (i.e., the midsole and outsole assembly is not useful by itself as footwear)). Further, the attachment system allows for adjustability and comfort with the slide 100 as the amount of overlap of the liners 120, 124 and the mating of the top strap insert 160 with the side 118 of the midsole 114 can be user/wearer selected during assembly (as shown in
In some preferred embodiments, the top strap or top strap insert 160 has a planar or flat body (until assembled with some bending into a curved shape as shown in
The top strap insert 160 may be provided with the other components (e.g., with the midsole and outsole assembly) or be manufactured and provided separately (e.g., manufactured by a different party such as a manufacturer local or more local to the assembling party). The top strap insert 160 may be provided in blank form such as with no or single coloring (e.g., white, black, or the like) with no or limited embellishments on upper or outer surface 162. The embellishing may be performed locally by the party assembling the assembled slide or footwear assembly 100 or may be performed by a separate party and then provided to the assembling party for use in assembly as shown in
In this design or option, the midsole and outsole assembly is provided without the wing liners 120, 124. As shown in
On the outer surfaces 222 and 228 of attachment supports 220, 226, the first and second components or elements 130, 132 of the attachment system (which may take the same form or a different form from those provided on the wing liners 120 and 124 in the assembly 100 of
Such assembly shown with arrows 230, 232, 240, 250, and 260 may be performed locally by the assembling party (or by a third party in some cases). The top strap insert 160 in this footwear assembly 200 may be identical to that provided in the assembly 100 of
The body 362 of the top strap insert 360 extends from a first or lower end 370 to a second or upper end 379, and the body 362 has an outer surface 364 and an inner surface 366. The body 362 is much longer than that used in the designs of
The lower section 374 of the strap body 362 is positioned within the passageway 317, and the side section 376 extends upward or orthogonal to the midsole 114. The top strap section 378 can then be moved so as to extend over the midsole 114 to allow the strap 360 to be attached back upon itself via the pair of attachment system elements 130 and 170 provided on opposite ends 370 and 379 of the body 362 of the strap 360 (as well as on opposite sides of the body 362). Particularly, as shown in
This reduces complexity of the construction, but, in the same way as in the designs of
Although the invention has been described and illustrated with a certain degree of particularity, it is understood that the present disclosure has been made only by way of example, and that numerous changes in the combination and arrangement of parts can be resorted to by those skilled in the art without departing from the spirit and scope of the invention, as hereinafter claimed.
