An athletic style shoe typically relies on a lacing structure to securely maintain the shoe to a wearer's foot. However, lacing materials may not be suitable or preferred by some wearers of the shoe. Consequently, a shoe may be designed to allow a wearer to slip into the shoe without adjusting laces. Unfortunately, traditional shoes may not securely fit to a wearer's foot if a forefoot opening and/or an ankle opening are maintained, in an as-worn position, large enough for a foot to be received. As a result, hook and loop materials may be utilized, in place of traditional lacing, to tighten a shoe to a wearer's foot. However, the hook and loop material may unintentionally detach from one another when a force is exerted by the foot within the shoe that exceeds the bonding force of the hook and loop material. This may also cause the shoe to not securely fit to the wearer's foot.

Having briefly described an overview of embodiments of the present invention, a more detailed description follows.
The construction of a slip athleisure shoe 10 of the present invention has the basic construction of a traditional basketball-type shoe. However, the slip athleisure shoe 10 is comprised of a first fastener 312 attached to the tongue and a second fastener 302 attached to the upper 202, as best seen in
In embodiments, the shoe 10 is a low-top basketball-style shoe. However, it should be understood that the novel concept of the invention could be employed on other types of shoes (e.g., high-top, infant, toddler, children, adult, cross-training, running, lifting, and the like). Because much of the construction of the shoe 10 is the same as that of a conventional shoe, the conventional features of the constructions will be described only generally herein.
The shoe 10 has a shoe sole 102 that is constructed of resilient materials that are typically employed in the construction of soles of athletic shoes. The sole 102 can be constructed with an outsole, a midsole, and an insert, as is conventional. The shoe sole 102 has a bottom surface that functions as the traction surface of the shoe, and an opposite top surface in the interior 12 of the shoe 10. The size of the shoe 10 has a length that extends from a rear sole heel end 106 to a front toe end 104 of the sole 102. As best seen in
The shoe 10 also is constructed with the upper 202. The upper 202 is secured to the sole 102 and extends upwardly from the shoe sole, such as the sole top surface. The upper 202 is constructed of a flexible material, for example leather, polymer, or a fabric such as canvas. The upper 202 is constructed with a heel portion 230 that extends around the sole 102 at the sole heel end 106. The upper heel portion 230 extends upwardly from the shoe sole 102 to an ankle opening 232. The ankle opening 232 provides access to the shoe interior. The upper has an interior surface 212 and an exterior surface 214. The interior surface 212 is traditionally exposed to the wearer's foot or other garments (e.g., socks). The exterior surface 214 is traditionally exposed to the outside environment and may define a portion of the exterior of the shoe 10.
From the heel portion 230, the upper 202 has a medial side portion 216 and a lateral side portion 218 that extend along the respective sole medial side 108 and the sole lateral side 110. The upper medial side portion 216 extends upwardly from the sole medial side 108 to an upper medial side edge 206. The upper lateral side portion 218 extends upwardly from the sole lateral side 110 to an upper lateral side edge 208. As illustrated in the figures, the upper medial side edge 206 and the upper lateral side edge 208 extend rearwardly from opposite sides of the front toe end 104 of the sole 102. As best seen in
The upper 202 is also constructed with a toe box 204 that extends around and across the sole top surface at the sole toe end 104. The toe box 204 is connected between the upper medial side portion 216 and the upper lateral side portion 218 and encloses a portion of the shoe interior 12 adjacent the sole toe end 104. The upper medial side edge 206 and the upper lateral side edge 208 extend rearwardly from the toe box 204.
A first plurality of apertures 240 are provided on the upper medial side portion 216 and a second plurality of apertures 242 are provided on the upper lateral side portion 218. The apertures 240 and 242 are lacing openings in an exemplary embodiment. A lacing opening is an opening that is typically occupied by a portion of a fastener, such as lacing that close the shoe upper over the forefoot opening of the shoe. The apertures 240 and 242 may provide any type of lacing openings on the shoe, for example, D-rings or speed lacing hooks. However, in an exemplary embodiment, the apertures 240 and 242 are an eyelet or grommet style aperture. The apertures 240 and 242 are arranged in lines along the upper medial side portion 216 and the upper lateral side portion 218, as is conventional. As illustrated in the figures, the apertures 240 and 242, in an exemplary embodiment, extend substantially the entire length of the upper medial side edge 206 and the upper lateral side edge 208. It is contemplated that a lacing material is not utilized with embodiments of the shoe; instead, the various other closure mechanism discussed herein may provide a desired method of securing the shoe to a wearer's foot.
The shoe upper 202 includes a vamp 222 or a throat positioned rearwardly of the toe box 204, and a tongue 224 that extends rearwardly from the vamp 222 through the forefoot opening 210. The tongue 224 extends along the lengths of the upper medial side portion 216 and the upper lateral side portion 218 to a distal end of the tongue, a tongue upper edge 229, near an ankle opening 232. As best seen in
The construction of the shoe 10, as previously discussed, includes a fastening combination along a first side of the tongue 224. For example, the fastening combination may be a hook material and a loop material used in combination to affix the tongue 224 and the upper 202. However, while hook and loop is discussed herein, it is understood that any combination of fastening materials may be utilized. For example, snaps, buttons, zippers, adhesive, stitching, lacing, tensioning mechanisms, or the like may be utilized as the first fastener 312 and/or the second fastener 302.
The first fastener 312, as best seen in
In an exemplary embodiment, the first fastener 312 has a length that extends a length of the forefoot opening 210 that is occupied by a plurality of apertures, such as the plurality of apertures 242. For example, while a traditional shoe may rely on laces extending through apertures to secure a shoe to a wearer, the first fastener 312 may perform a similar function along the same portion of the upper 202 as would be served by the apertures. However, it is understood that the first fastener 312 may extend for only a portion of the tongue 224 or the whole length of the tongue 224 as covered by the upper 202 along the forefoot opening 210. Additionally, it is contemplated that the first fastener 312 is a plurality of fasteners working in combination to achieve a similar result. For example, discrete portions of a hook or loop material may be affixed to the tongue 224 to serve as the first fastener 312. Further examples may include individual snaps, buttons, or other fasteners may achieve a similar result.
The second fastener 302 is affixed to an interior surface 212 of the upper 202 proximate the forefoot opening 210 opposite the first fastener 312. Consequently, the second fastener 302 may work in combination with the first fastener 312 to removeably affix the tongue 224 with the upper 202. The second fastener has a perimeter defined by a medial edge 304, an opposite lateral edge 306, a toe end 310, and an opposite heal end 308. The first fastener 312 and the second fastener 302 may have perimeters with similar dimensions to effectively couple with one another. Similar to the first fastener, the second fastener has a length defined as extending from the toe end 310 to the heel end 308. Further the second fastener 302 has a width extending from the lateral edge 306 to the medial edge 304. However, as also previously discussed with respect to the first fastener 312, it is contemplated that the second fastener 302 may be comprised of a plurality of discrete fasteners that accomplish a similar result. For example, it is contemplated that a plurality of snaps, buttons, or the like that extend along a length that is different or similar to the illustrated length of the second fastener 302.
In an exemplary embodiment, the second fastener 302 extends along the upper edge (e.g., the upper medial side edge 208) of the upper 202 where the upper edge defines the forefoot opening 210. For example, as illustrated in
In an exemplary amendment, the second fastener 302 is a loop material and the first fastener 312 is a hook material. However, it is contemplated that the second fastener 302 is a hook material and the first fastener 312 is a loop material.
Turning to the other side of the shoe 10, the stretchable member 402 is affixed, either permanently or temporarily, to both the tongue 224 and the upper 202. The stretchable member is a flexible material having elastic characteristics. For example, the stretchable member 402 may be an elastic banding material having a measured resistance to elongation. Therefore, depending on a desired amount of resistance, the material stretchable member 402 may be adjusted to achieve the desired resistance. The resistance, as will be discussed hereinafter, is utilized to maintain the shoe 10 on a wearer's foot instead of, or in addition to, traditional lacing.
The stretchable member 402 provides an amount of “give” or “play” to the shoe 10 when secured to a wearer's foot. Therefore, when a wearer exerts a force that is transferred through the shoe 10, traditional shoes that rely solely on hook and loop fasteners that have minimal “give” may disengage causing the shoe to change positions on the wearer's foot. For example, a child may wear a pair of shoes that rely on hook and loop fasteners to allow the shoe to expand, in an un-attached position, to receive the child's foot. The hook and loop material may then be attached to secure the child's foot. When the child begins to run, the hook and loop fastener(s) may fail (e.g., become un-attached in whole or in part) because the force exerted on the hook and loop fastener exceeds the force for which the fastener can resist.
Consequently, it may be desirable to utilize, in combination, a hook and loop fastener along with a stretchable member. For example, when the same child above begins to run in an embodiment of the present invention, the stretchable member may stretch to absorb some of the force exerted by the child. The absorption of the force by the stretchable member reduces the force experienced by the hook and loop fastener. As a result, a shoe utilizing the first fastener 312 with the second fastener 302 and the stretchable member 402 may provide a shoe securing mechanism that is able to absorb force while maintaining the shoe in a desired as-worn position.
As illustrated in
The stretchable member 402 may be secured or otherwise affixed to the upper 202 and the tongue 224. For example, an aspect illustrated in
The stretchable member 402, as illustrated in
As best seen in
It is contemplated that the shoe 10 may be used in the following exemplary manner, in accordance with embodiments of the present invention. A wearer of the shoe 10 may disengage the first fastener 312 from the second fastener 302 to un-affix the lateral side of the tongue 224 from the upper 202. This separation of the tongue 224 from the upper 202 proximate the lateral side provides easy access to the shoe interior 12 through both the forefoot opening 210 and the ankle opening 232. The wearer may then slip his or her foot into the shoe 10 utilizing the forefoot opening 210 and the ankle opening 232. The tongue 224 may be displaced even farther from the upper 202 by allowing the stretchable member 402 to extend in length, which may facilitate easier entry into the interior 12.
Once the shoe 10 is positioned to the wearer's foot, the wearer may align the first fastener 312 with the second fastener 302 to maximize contact area between the two fasteners, which may maximize a bonding strength between the two fasteners. However, it is also contemplated that the wearer may adjust the location of the tongue 224 and/or the alignment of the first fastener 312 relative to the second fastener 302 to achieve a desired tension across the shoe 10 for securing to the wearer. Once secured, the shoe 10 is in an as-worn position on the wearer. Consequently, as the wearer exerts a force that is intended to be translated from the wearer's foot through the shoe 10 to the contacting surface, the stretchable member 402 may stretch to reduce the force experienced by the first fastener 312 and the second fastener 302. This reduction in force may prevent the first fastener 312 and the second fastener 302 from unintentionally disengaging from one another. As a result, a wearer of the shoe 10 may access the interior 12 utilizing the convenience of a hook and a loop fastener while minimizing the possibility of an unintentional disengagement of the hook and loop fastener when worn by relying on the stretchable member 402 to absorb energy that could otherwise cause the unintentional disengagement.
The terms medial and lateral have been used herein to describe a relative location of features, portions, and/or elements of the shoe 10. However, it is contemplated that aspects of the invention may substitute one relative term for the other. For example, it is within the scope of the present invention for the features identified on the medial side of the shoe 10 to also, or in the alternative, be located on the lateral side and vice versa. Therefore, while the description herein is focused, for ease of understanding, on the stretchable member 402 being located on the medial side and the combination of the first fastener 312/second fastener 302 being located on the lateral side, it is contemplated that the opposite (i.e., the stretchable member 402 located on the lateral side and the combination of the first fastener 312/second fastener 302 located on the medial side) may also be implemented within the scope of the present invention.
Although the shoe construction is described above by referring to particular embodiments, it should be understood that the modifications and variations could be made to the shoe construction described without departing from the intended scope of protection provided by the following claims.
