The present invention relates to footwear and, more particularly, to a reversible strap for an article of footwear.
There are a variety of styles and designs of footwear, including shoes, sandals, boots, and the like, including features that serve functional and aesthetic purposes. For example, many footwear constructions include hook and loop straps. Hook and loop straps provide easy and rapid closure, varying degrees of tightness, and uniform support for the foot. While serving a functional role, these and other straps can include decorative elements to add to the aesthetic appeal of the article of footwear.
Hook and loop straps are typically are limited to a single aesthetic appearance, however. While reversible tongues and reversible sandals are known, their reversible constructions are not well suited for hook and loop straps or other strap closures, including buckle clasps, magnetic clasps, and other attachments. Accordingly, there remains a need for an article of footwear having straps that can be configured by the wearer. In particular, it would be advantageous to provide an adjustable strap that can be easily reversed to change the aesthetic appearance of the article of footwear.
A reversible strap for an article of footwear is provided. The reversible strap includes a strap-end and a strap-body. The strap-body includes a first surface on one side thereof and a second surface on the other side thereof. The wearer can manually manipulate the strap-body to select between the two surfaces, which are visually or functionally distinguishable from each other. The strap-end detachably secures the strap-body to the article of footwear and can complement any visual markings on the strap-body.
In one embodiment, the strap-body is reversible and the strap-end is non-reversible. The strap-body may include an attachment on both sides so that regardless of the orientation of the strap-body, there is an attachment on the upper side of the strap-body and an attachment on the lower side of the strap-body. The strap-end may be configured to cover and conceal the attachment on the upper side. The strap-end may include an attachment that is operatively engaged with the attachment on the upper side of the strap-body. The strap-end may also include an attachment that is operatively engaged with a corresponding attachment on the upper.
In another embodiment, the strap-body is anchored to the medial or lateral upper of the article of footwear. The strap-body is twistable about its longitudinal axis between a first position in which a first surface is displayed and a second position in which a second surface is displayed. The strap-body includes an end portion with an attachment on opposing sides thereof, and includes a double-sided construction having first and second coextensive layers joined about their respective periphery.
In still another embodiment, the strap-end is rotatably joined to the strap-body, and includes a displayable side opposite an attachment side. The displayable side can complement visual markings on the strap-body, and the attachment side can secure the strap-end to the upper and/or to the strap-body. For example, the strap-end can include a bottom layer for attachment to the upper and a top layer extending over the bottom layer for attachment to the strap-body. In this example, an attachment can detachably join the strap-end to both of the strap-body and the upper. Further by example, the strap-end can include a single layer for attachment to the strap-body. In this example, an attachment can detachably join the strap-end to only the strap-body, and not the upper. The attachment can include, for example, a hook and loop attachment, a snap attachment, a friction attachment, or a magnetic attachment.
The reversible strap can provide a quick and convenient manner in which the aesthetic appearance of the article of footwear may be adjusted. For example, the user can detach the strap-end from the upper, pulling back on the reversible strap. The user can then detach the strap-end top layer from the strap-body and rotate the strap-body about its longitudinal axis. With a different surface showing, the user can re-attach the strap-end top layer to the strap-body and lower the reversible strap onto the article of footwear. The upper engages the attachment of the strap-end and the strap-body to provide improved retention of the reversible strap.
In another embodiment, the strap-end is joined to the upper, rather than to the strap-body, and includes a panel extending over the end portion of the strap-body. The panel includes a displayable side opposite an attachment side. The displayable side can complement visual markings on the strap-body, and the attachment side can engage the strap-body, such that the strap-body is sandwiched between the panel and the upper. The strap-body is twistable about its longitudinal axis between a first position in which a first surface is displayed and a second position in which a second surface is displayed. The first and second surfaces can provide different visual indicia or different functional characteristics, for example. In use, the wearer can detach the panel from the strap-body and pull back on the strap-body. The wearer can then rotate or twist the strap-body such that a different surface is visible. The wearer can then lower the strap-body onto the upper and lower the panel onto the strap-body. Both the strap-end and the upper engage the strap-body to provide improved retention of the reversible strap.
These and other advantages and features of the invention will be more fully understood and appreciated by reference to the description of the current embodiments and the drawings.

Lastly, the term “longitudinal axis” includes the lengthwise axis of symmetry of the reversible strap.
Referring now to
The sole component 104 provides protection for the wearer's sole, while also providing flexibility for a range of foot movements. The sole component 104 includes a midsole 114 and an outsole 116 in the illustrated embodiment, but greater or fewer elements of the sole component 104 can be included in other embodiments. For example, some embodiments can include only an outsole, while other embodiments can include an outsole, a midsole, and an insole. Still other embodiments can include a unit sole, in which the midsole and the outsole are combined into a unitary element.
The reversible strap 10 includes a strap-body 12 and a strap-end 14. The strap-body 12 is rotatably joined to the upper 102, such that the strap-body 12 can be twisted about its longitudinal axis. The strap-body 12 is joined to a first rotatable element or anchor 16, which is joined to the upper 102. The anchor 16 can include any construction that is twistable with manual manipulation of the strap-body 12. For example, the anchor 16 can include one or more strips of flat shoe lace, round shoe lace, flat elastic gore, round elastic gore, leather, polyurethane, or other textile. Where two or more strips are used, the strips can be arranged in an “X”, such that the anchor 16 is rotatable about the juncture between the two strips. The anchor 16 can be sewn or otherwise fixedly attached to the upper 102, optionally being sandwiched between a layer of webbing 118 and the upper 102 as shown in

The strap-end 14 is rotatably joined to the second end portion 22 of the strap-body 12. In particular, the strap-body 12 is twistable relative to the strap-end 14 with manual manipulation of the strap-body 12 when the reversible strap 10 is in an open position as shown in
The strap-end 14 is adapted to join the strap-body 12 to the upper 102. The strap-end 14 includes a displayable side 26 and an attachment side 28. The displayable side 26 is generally shown in
An attachment 34 detachably joins the strap-end 14 to both of the strap-body 12 and the upper 102. The attachment 34 can include, for example, a hook and loop attachment, a snap attachment, a friction attachment, or a magnetic attachment. The attachment 34 includes a hook and loop attachment in the illustrated embodiment. For example, the second end portion 22 of the strap-body 12 includes a loop fastener on opposing surfaces thereof. The downward facing surface of the top layer 32 of the strap-end 14 includes a hook fastener to engage either surface of the strap-body 12. The downward facing surface of the bottom layer 30 of the strap-end 14 includes a loop fastener to directly or indirectly engage the upper 102. The upper 102 includes, on an upward facing mating surface 118, a hook fastener to engage both of the strap-end 14 and the strap-body 12. The mating surface 118 is generally oversized with respect to the strap-end 14, such that the reversible strap 10 can be tightened or loosened with respect to the upper 102 during normal wear.
In these and other embodiments, the second end portion 22 of the strap-body 12 includes upper and lower receiving surfaces, and the strap-end 14 includes a downward facing mating surface to selectively engage the strap body 12 and a downward facing receiving surface to selectively engage the upper 102. Similarly, the upper 102 includes an upward facing mating surface 118 to selectively engage the receiving surfaces of the strap-end 14 and the strap-body 12. Consequently, the upper and lower receiving surfaces of the strap-body 12 are sandwiched between the strap-end 26 and the upper 102 when the reversible strap 10 is seated over the upper 102. The receiving surfaces are described as being loop fasteners and the mating surfaces are described as being hook fasteners, but in other embodiments the receiving surfaces can be hook fasteners and the mating surfaces can be loop fasteners. In addition, the mating surfaces can include magnets to engage the receiving surfaces in the foregoing manner. Other attachments include snap attachments and friction attachments, for example.

Though described above in relation to visual indicia, the upper and lower surfaces of the strap-body can instead perform different functions. For example, the upper surface can provide a solar heat absorption function, while the lower surface can provide a heat dissipation function. When twisted, the upper surface can provide a heat dissipation function, and the lower surface can provide a solar heat function. In this regard, the wearer can select between solar heat absorption and heat dissipation. In addition, the upper surface can provide a moisture barrier, and the lower surface can provide a moisture wicking surface. When twisted, the upper surface can release moisture that was absorbed into the moisture wicking surface. In addition, the upper surface can provide a reflective function, while the lower surface can provide a camouflage function. When twisted, the upper surface can provide a camouflage function, and the lower surface can provide a reflective function. In this regard, the wearer can select between reflective and camouflage functions. The reversible strap according to these and other can extend across essentially any portion of the upper, including lateral portions, medial portions, and reverse-facing heel portions, for example.
The strap-body can also include a stacked arrangement of panels joined together in an accordion-like manner. The panels can include different visual indicia thereon, or can perform different functions. Panels joined together in an accordion-like manner are set forth in US Patent Application Publication 2015/0033583 to Loverin et al, the contents of which are incorporated by reference in their entirety. Further by example, the strap-body can include a plurality of panels that are longitudinally joined to each other, such that the wearer can select an upper surface from one of the plurality of panels. Still further by example, a first plurality of panels can be joined to the upper layer of the strap-body along the longitudinal edges thereof, and a second plurality of panels can be joined to the lower layer of the strap-body along the longitudinal edges thereof. The strap-body can be manually manipulated as follows. Beginning from the closed position, the wearer can pull back on the strap-end. The strap-end and the strap-body release from the upper. From this open position, the wearer can detach the upper layer of the strap-end from the strap-body. Once detached, the wearer can manually manipulate the plurality of panels until the desired panel is presented. The wearer can then reattach the strap-body to the strap-end. The wearer can then lower the strap-end and the strap-body as an integrated reversible strap onto the upper. From the closed position, the reversible strap now presents a different surface of the strap-body.
