DESCRIPTION OF EMBODIMENTS
[0024] As used in this description, the term “orthotic insert” means non-prescription foot inserts and/or orthotics that provide support to the foot forefoot, arch region and/or hindfoot.
[0025] According to the various embodiments of the invention, modified footwear in the form of a slipper 150, as shown in FIG. 1, comprises an insole 1, an upper 7, and a repositionable arch receptacle 2. An open-ended heel receptacle 5 having the opening oriented toward the midsole of the insole 1 is further provided, into which may be inserted a heel insert 6. In this embodiment the modified footwear system is incorporated into a slipper, such as a house or bedroom slipper. When the receptacles 2 and 5 are securely positioned on and affixed to the surface of the insole they hold the inserted orthotics in place so they cannot move around when the user's foot is inserted, even though the back of the slipper is open (FIG. 2). The heel receptacle may be fixed in place, for example by sewing or being integrally molded with the insole, or it may be fully detachable and repositionable. The embodiments of FIGS. 1 and 2 can for example be cloth slippers suitable for house wear. They are made of one or more fabrics and are lightweight, easy to wash and dry and packable, while at the same time having the ability to accommodate, support and fixedly retain insoles inserted into the receptacles therein. In this manner, house slippers, which typically do not provide relief, and which even exacerbate foot conditions because of their traditional lack of support, can be augmented in a novel way to provide support and pain relief. A further advantage of the invention with respect to slippers and sandals is that the repositionable receptacles may be easily inserted and removed because those footwear are characterized by an open vamp. In this respect, it is easier to customize the position of the receptacles.
[0026] In the embodiment of FIG. 3, the repositionable receptacle 2 is secured to the surface of the insole by removable attachment means 3a and 3b. In a preferred embodiment the attachment means are strips of reclosable hook and loop tape, such as is marketed for example under the brand name, VELCRO™. In alternative embodiments, adhesive strips such as stretch releasing adhesive strips sold under the brand name COMMAND™ by the 3M Innovative Properties Company, or other clean release adhesive may be used to secure the arch and/or heel receptacles. Alternative, the heel receptacle may be sewn or molded onto the surface of the heel area of the insole 1.
[0027] FIG. 3 further provides an exploded view of an assembly of an embodiment in which the slipper or soft-soled footwear comprising the repositionable receptacles may be attached to a detachable sole 11. In this respect, lower attachment sleeve 8 is attached to the underside of the insole 1 at the front or forefoot region thereof, thereby providing a sleeve opening oriented toward the midsection of the sole. Similarly, lower attachment sleeve 9 is attached at the heel or hindfoot area of the insole 1. It should be noted that while in the figure the attachment sleeves are attached to the underside of the insole, they may similarly be attached to a midsole layer 18 between the insole and the sole, as is depicted in FIG. 4. Also as shown in FIG. 9, each attachment sleeve may be open at both ends and attached to the midsole (or insole, in other embodiments) at the midsection thereof. In certain embodiments, attachment sleeves may be open-ended (shown as elements 16, 17) to allow for attachment of an outsole inserted through the sleeves from one direction or another.
[0028] The lower attachment sleeves 8 and 9 (or 16, 17) may be cooperatively attached to a detachable outsole 11 (FIGS. 3,4). For example, the outsole may be a hard sole, such as that of a sandal or shoe. This type of sole may be made of any suitable material suitable for protecting the soles of the feet from external injury or impact, and for maintaining the structural integrity of the shoe, including without limitation, rubber, cork, leather, thermoplastics or other synthetic materials. The outsole may be waterproof. The detachable outsole 11 may be of a flatter style, i.e. a substantially horizontal configuration, or a heeled style, and it is preferably suitable for outdoor wear. The outsole 11 may also be an athletic sole or any other form of sole that might be selected for specialty footwear. The detachable outsole 11 comprises insertion slots 12 and 13 in the forefoot and hindfoot (heel) regions thereof, respectively. The upper, insole and midsole are attached to the outsole 11 by insertion of the lower attachment sleeves 8 and 9 into the insertion slots 12 and 13, respectively. By attaching to an outsole as is described, soft-soled footwear such as a bedroom slipper which contains the insole with repositionable receptacles of the invention may be attached to a hardier, more durable outsole, for example for outside wear. If the outsole is made of a waterproof material it can be washed or hosed off as needed and air dried. In this way a single footwear system of the invention may be modified to provide footwear for a different purpose without the user being required to purchase and install separate orthotic footwear systems for each type of shoe. Additionally, when the soft-soled footwear, for example a cloth house slipper, becomes worn, it may be disposed of without having to dispose of the entire shoe. The soles may be retained for use with another pair of cloth slippers. This eliminates solid waste and allows for recycling of a percentage of the shoe's parts.
[0029] The receptacles 2 and 5 may be constructed from the same material as the insole or the upper, or they may be made from a fabric material, for example breathable or moisture-wicking fabric, such cotton or terrycloth. Alternatively, the receptacles may be formed from thermoformable materials or from rubber. In preferred embodiments, the insole and upper are made from biodegradable fabric. The arch receptacle 2 is repositionable, while the open-ended heel receptacle 5 may be repositionable or in various embodiments it may be permanently affixed to the surface of the insole. As shown in FIGS. 8A and 8B, a further embodiment of the invention comprises an insole that includes an additional detachable and repositionable metatarsal receptacle in the foot bed region to accommodate an insert, such as metatarsal pads that cushion the ball of the foot.
[0030] As depicted in FIG. 5 a soft-soled embodiment of the invention 100 as shown in FIG. 1 or 2 is insertable into a conventional shoe 200 such as a clog or mule. In this manner the orthotic support provided by the novel and inventive aspects of the invention may be included, for example, in a backless shoe. Similarly, the soft-soled embodiment may be inserted into a closed shoe, boot or sneaker. It should be understood that slipper or insertable footwear embodiments of the invention are not limited to soft soles, for example fabric soles, but the sole of the footwear that inserts into another shoe may be of less flexible material and construction as well.
[0031] The invention may also be manufactured and sold as a separate insole which can be inserted into any shoe according to the size of the insole, as in FIG. 6. The one or more repositionable receptacles can be used to accurately position the arch, metatarsal (shown in FIGS. 8A, 8B) and heel receptacles according to the contours of the customer's foot when the insole is inserted in the shoe.
[0032] FIGS. 7A and 7B show hosiery embodiments of the invention in which receptacles 2, 5 are attached within hosiery apparel 300, 301, for example a sock or stocking. The fabric may be thin or transparent, such as a stocking sheer material used for stockings or pantyhose, or it may be made of knit or woven material, provided that the fabric is sufficiently durable to allow attachment of the receptacles without damage to the fabric. In these embodiments the receptacles may alternately be fixed in the stocking for, for example by being fused or woven in. The hosiery of the invention may be worn by the user with open shoes while still providing the foot support benefits from the orthotic inserts.
[0033] The upper of the shoe configurations of the invention may vary in shape and may be constructed of materials such as fabric, leather, woven natural materials or synthetic materials. FIGS. 10A and 10B depict an embodiment of the invention in which the upper is a vamp composed of two segments that may be folded and attached together, for example by buttons, snaps or reclosable hook and loop fastener tape. The segmented vamp allows for easy placement of the repositionable receptacles on the upper surface of the insole and also for easy insertion of the orthotic inserts into the repositionable receptacles and the optionally repositionable heel receptacle. One or more repositionable receptacles may be fitted with orthotic inserts, as shown. The right foot of each pair shows the inserted orthotic.
[0034] The products of the invention, namely the insoles, slippers, shoes or hosiery, may be sold with or without orthotic inserts. In this regard, a user may change or replace the orthotic without having to dispose of the entire insole, or to reorder the entire shoe. The footwear of the invention allow for continued use of traditional adhesive-backed inserts even after the adhesive has worn away because the insert can be held in the desired fixed position when inserted into the receptacles according to a method of the invention.
[0035] It should be understood that the shapes and dimensions of the receptacles described herein and depicted in the figures are not limited by the present description or said figures.
[0036] In a method of use, footwear or the insole purchased according to embodiments of the invention may be customized first by adjusting the placement of the repositionable receptacles in the arch region and at the heel. Then, further custom fitting may be achieved by changing the size, shape and function of the orthotic insert. In other applications of use, the repositionable receptacles may be attached and repositioned on the insole or the sole portion of the hosiery of the invention.
INDUSTRIAL APPLICABILITY
[0037] Various types of footwear can either be created or modified according to the various embodiments of the invention described herein and other embodiments representing the inventive concepts set forth herein that would be readily envisioned by a person of ordinary skill in the art. The modified footwear of the invention can be used in many applications, including but not limited to casual footwear, bedroom slippers, hosiery, thin shoe liner footwear, and insoles for insertion into shoes, sandals or boots.
