The present invention relates to the field of footwear and particularly to releasable attachment of soles to footwear.
This invention relates to methods and systems which facilitate releasable attachment of soles to footwear.
Conventional footwear design provides footwear with soles that allow a user's feet to stay warm, dry, and safe from injury. Often, though, when users are indoors, they prefer to wear slippers so as not to drag dirt into their homes or offices. Slippers, many of which have sturdy soles, are useful for when a user goes into a room with a cold tile floor, or even a child's playroom, where small toys and other stepping hazards are frequently strewn across the floor.
Many people prefer wearing socks alone to wearing slippers, especially when the socks are thick and comfy such as those made of fleece wool or fleece fabric, fur or fur lined fabric, sherpa fabric lined suede, or sherpa fabric lined sueded material, or thick knits. However, when users need additional sole protection, they often reach for their slippers, but slippers are not a good choice to wear outdoors or in garages or unfinished basements, because afterwards, the slippers are then dirty and, in the case of an outdoor trip, sometimes wet. When users reach for shoes as sole protection, they often find that their shoes are too small to fit over those thick socks.
Various sock/sole combinations have been proposed in the art that teach releasably connecting soles using elements that are disposed in the upper surface of the sole, which may be uncomfortable for a user to walk on or stand in. US 20080005927 (Hung) teaches a sock/sole combination with a first connector on the bottom of the sock that attaches to a second connector on the upper surface of an interchangeable sole, the first connector having a thickness with a predetermined wear proof effect and the connector pairs being VELCRO™ fasteners (magic tape) or equivalent separable fasteners. US 20160242504 (Crowley) discloses a footwear assembly secured by magnetic elements onto which a user stands, with a detachable sole having a first set of magnetic elements on its upper surface, and a footwear item such as a sock having a second set of magnetic elements on its bottom surface, and featuring strategic placement of magnets of differing polarities to facilitate proper attachment and discourage incorrect attachment and a wedge-shaped projection from its heel that allows a user to urge or press on it with one foot to facilitate detachment.
It is desirable to have a simple, convenient, securely attachable sole for footwear in which the sole attaches and detaches hands-free so that a user can put on and take off without bending down, in which the assembly is comfortable for the user to wear, and a user may keep thick socks on while leaving indoors without getting the socks dirty or wet.
A footwear assembly or assembly with a releasably attachable sole has a sock and a water resistant oversock that is arranged to cover the user's toes and heels. The sock has a sock sole, an upper edge, a heel (sometimes referred to as a “heel flap”) between the sock upper edge and the sock sole, and a sock attachment site that is located on or near the sock heel. The oversock, which may be water resistant and may be sized to fit over the sock when the sock is worn on a foot of the user, may have an oversock sole, an oversock rear section sized to contain at least a portion of a user's heel, and a toe cap sized to contain the sock over the user's toes. The oversock sole may be formed at least in part of a material that is stretchable to impart stretchiness along a length of the oversock between the toe cap and the oversock rear section. The oversock may have a rear edge with a protrusion extending outwardly from the oversock sole and sized to allow a second foot of the user to step thereon and to stretch the oversock sole between the toe cap and the oversock rear section. The oversock sole may have an oversock attachment site that is located on the oversock rear section and that corresponds in location to the sock attachment site. A user may releasably attach the sole to the footwear by putting the sock on his or her first foot, putting the oversock on over the sock, and using the user's second foot to stretch the oversock along the length of the oversock sole to fit the user's first foot into the oversock. The sole is stretched by the user pressing his or her second foot down on the protrusion extending outward from the oversock sole at the oversock heel. The sock is releasably secured into the oversock with corresponding elements of an attachment fastener on the sock and the oversock, which are brought into releasable attachment at a sock attachment site and a corresponding oversock site.
The footwear may also have an attachment fastener with a first attachment element that is located on the sock at the sock attachment site and a second attachment element that is located on the oversock at the oversock attachment site. The second attachment element may be releasably attachable to the first attachment element when the oversock is worn over the sock on the foot of the user.
In one embodiment, the oversock attachment site may touch the sock attachment site when the oversock is worn over the sock on the foot of the user.
In other embodiments, the oversock attachment site is magnetically attachable to the sock attachment site when the oversock is worn over the sock on the user's foot. In a further embodiment, the attachment fastener may have a set of magnetically attractable elements, the first attachment element being a first magnetically attractable element attachable to the sock at the sock attachment site, and the second attachment element being a second magnetically attractable element attachable to the oversock at the oversock attachment site. In still further embodiments, the first attachment element is located within the sock at the sock attachment site. The sock attachment site may have an interior layer and an exterior layer, and the first attachment element may be located between the interior layer and the exterior layer.
In further embodiments the oversock extends upward from the oversock sole to contain a portion of sides of a midfoot of a user. In still further embodiments, the oversock has an instep arch on a foot-facing surface of a sole of the oversock, and a patterned surface on a ground-facing surface of a sole of the oversock, and the oversock lacks an instep cover so that an instep of the user's foot is not enclosed at least in part.
In other embodiments, a water resistant oversock is sized to fit over a sock when the sock is worn on a foot of the user. The oversock may have an oversock sole, a rear section sized to contain at least a portion of a user's heel, a toe cap sized to contain the sock over a user's toes, and a protrusion extending outwardly from the sole. The oversock also may have an oversock attachment site that is located on the oversock rear section and that corresponds in location to a sock attachment site that is located on a heel of the sock. The oversock may also have an oversock attachment element that is located on the oversock attachment site and is releasably attachable to a sock attachment element on the sock at the sock attachment site when the oversock is worn over the sock on the foot of the user.
On other embodiments, a sock that is sized to fit under a water resistant oversock when the sock and oversock are worn on a foot of the user, may have a sock sole, an upper edge, a heel between the sock upper edge and the sock sole, and a sock attachment site that is located on the sock heel and that corresponds in location to a oversock attachment site on the oversock that is located on a rear section of the oversock. The sock may also have a sock attachment element that is located on the sock attachment site and is releasably attachable to an oversock attachment element on the oversock at the oversock attachment site when the sock is worn under the oversock on the foot of the user.
In other embodiments, a method is disclosed in which a sock is put onto a first foot of a user, with the sock covering the toes of the user; a water resistant, stretchable oversock having an oversock toe cap is put onto the first foot over the sock to cover at least a portion of the toes of the user; and the oversock is stretched along the length of a sole of the oversock with a second foot of the user to fit the first foot into the oversock; and bringing corresponding elements of an attachment fastener into releasable attachment, with a first element of the corresponding elements located on a sock attachment site on or near a heel of the sock and with a second element of the corresponding elements located on an oversock attachment site that corresponds in location to the sock attachment site when the oversock is worn over the sock of the first foot of the user.
In further embodiments, the corresponding elements of an attachment fastener may be a first magnetically attractable element attached to the sock attachment site, and a second magnetically attractable element attached to the oversock attachment site. The corresponding elements of the attachment fastener may be brought into releasable attachment by bringing the first magnetically attractable element into alignment with the second magnetically attractable element when the oversock is put on over the sock on the first foot.
In still further embodiments, the oversock is stretched with the second foot by placing the first foot bearing the oversock onto a surface; with the second foot, stepping onto a tab extending outwardly from the oversock sole on a rear edge of the oversock sole; and with the second foot, pressing the protrusion against the surface while sliding the first foot the first foot forward and away from the second foot and into the oversock toe cap.
The disclosed footwear assembly and method for releasably attaching a sole to the footwear is very adaptable and may be used to simply, conveniently, and securely attach a sole to a sock and detach it hands-free without bending down. Further, the sock/oversock footwear assembly is comfortable for the user to wear, and allows a user to keep thick socks on, clean, and dry during a quick trip outdoors or to a location where the floor may dirty or wet.
Additional objects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.

It may be seen that the embodiments of the footwear assemblies and related methods for attaching a sole to footwear disclosed here may be used to greatly simplify convenient, secure releasable attachments of soles to footwear. Many features are described that may be included in footwear assemblies to make footwear with removable soles comfortable for the user to wear, and help a user to keep thick socks on while leaving indoors without getting socks dirty or wet. In addition, the disclosed systems and methods reduce environmental stress because a sock or oversock may last longer than the other, and the worn out component may be replaced so that the footwear assembly may remain usable. Further, a user may obtain several pairs of socks for the footwear assembly for replacement use in the footwear assembly when the original pair of socks become dirty or otherwise unwearable, or when the user desires a change of socks for any other reason.
In addition, although the disclosed components have been described above as being separate units, one of ordinary skill in the art will recognize that functionalities provided by one or more units may be combined. As one of ordinary skill in the art will appreciate, one or more units may be optional and may be omitted from implementations in certain embodiments.
