The present invention relates to water or swim shoes and to braces for feet.
Enjoyment of water sports, even as simple as water slides and swimming, is problematic for children and adults who must wear braces on their feet. Braces, by their nature, are typically comprised of materials that should remain dry, and drying wet braces is time consuming and sometimes tedious.
Brace manufacturers typically advise against swimming in the ocean, lakes or swimming pools, or even taking a shower, while wearing braces or supports and orthoses in general. Soft braces can absorb water, which makes them heavy, so they can slip and no longer remain in the proper location. Salt water particularly can attack the materials in the supports and orthoses and impair both the efficacy and the comfort in wear of the medical device.
Nevertheless, from a therapeutic point of view, and even for enjoyment of water activities, it can be necessary to wear a brace in water. A need exists for ways a person can wear braces in water without concern about damaging the braces with the water and without having the time consuming task of drying the braces afterwards. A need exists for a supportive and protective water shoe that enables the wearer to have needed support and protection in water that would be usually be afforded by a brace without the wearer having to wear their usual brace in the water.
The present invention meets these needs with a water or swim shoe that provides an ankle and foot orthotic to support a foot for swimming or any other water exercise or recreation. The orthotic has a general “L” shape comprising a lower horizontal portion and an upper vertical portion and is comprised of a hard, rigid material resistant to or effectively unchanged by water (or salt water), such as, for example, hard plastic or a polymeric material, or aluminum or an aluminum alloy not including any iron) and sufficiently strong to serve its purpose as an orthotic.
The horizontal portion of the orthotic is tucked inside the heel end of the shoe and lies in a trench within the sole. The vertical portion of the orthotic extends from the heel end upward adjacent the leg of the wearer. These horizontal and vertical portions join in an obtuse curved angle to form the corner of the general “L” shaped orthotic behind the heel end of the shoe. One or more straps, preferably with padding or pads, hold the orthotic to the leg with elastic or a fastener or securer comprised of, for example, a hook and loop closure, snaps, or ties. Similarly, one or more straps on the shoe body allow for adjustment of the fit of the shoe on the foot.
The body of the shoe is comprised of a porous or mesh type water resistant, non-absorbent, or quick-drying material and has one or more larger holes for water drainage. The sole of the shoe is comprised of rubber or synthetic rubber or a similar water resistant vinyl, and in one embodiment can extend over the top of the toe end of the shoe for protection of the toes. The body of the shoe also has a support, preferably with padding, in the area of the person's ankle. In one embodiment, the shoe appears somewhat like a sandal, with no covering extending up the leg. In another embodiment, the shoe body has comprises more material, more like a sneaker. In still another embodiment, the shoe has a sleeve that extends at least partially up the leg to help hold the orthotic in place. Such sleeve is comprised of neoprene or other water-resistant material and can be porous.
The present invention provides and all in one, supportive shoe, for use in and around water. In one embodiment, the shoe has interchangeable levels of support. In the embodiments, shown in the Figures, the water or swim shoe 10 of the invention has a built in orthotic device 12 to support the wearer's ankle and lower leg and provide stability for persons with weak lower limbs, foot drop, or other diagnosis' which require orthotic devices.
In the embodiments shown in
The hard orthotic 12, similar in the embodiments shown in
In some embodiments not shown, the orthotic 12 is removable and interchangeable to allow for different levels of support. In such embodiment, the orthotic 12 is attachable to the shoe with attachers such as, for example, straps, clips, screws, or clamps, and the like, and the orthotic is positioned at least in part in the sole 14 of the shoe 10, just as shown in
In some other embodiments, the orthotic device 12 is permanently affixed to the shoe 10, as shown, for example, in
As shown in
Pad 46, as shown in
Pad 46 is comprised of a material that prevents strap 45 from chafing the leg of the wearer, such as a foam material or shearling, and should be a material that maintains its function when wet, does not disintegrate in water, and preferably dries quickly. Pad 46 should have an exterior layer or backing that is capable of receiving the fasteners 50 for firmly holding the orthotic 12 to the pad 46 without tearing or stretching. One example is a soft plastic backing material.
Similarly, pad 46 should be sufficiently strong as to receive the fastener(s) 51 for firmly holding the strap 45. Strap 45 can itself optionally have some padding comprised of material like that or similar to that comprising pad 50, and strap 45 is otherwise comprised of a silicone, soft plastic, rubber or synthetic polymeric or rubber type material, or an elastic type material, that is water resistant, or non-absorbent and quick drying, and substantially or effectively unchanged by water, and that is strong enough to hold the pad 45 which is holding the orthotic 12 to the wearer's leg during use in water. The configuration of the strap 45 attached to the pad 46 with buckle frame and bar 52 as shown in
After adjustment of strap 45 to fit the leg of the wearer, strap 45 is closed or fastened in place, for example, with a hook and loop closure such as “Velcro®,” a registered trademark of Velcro Industries, B.V., or one or more buckles, ties, snaps, or similar fasteners.
The person's ankle will be supported, in the embodiments shown in the Figures with a support (not shown) in the ankle area 30, which preferably will have a pad or padding (not shown) between it and the person's ankle. As shown in
In the embodiments shown in the Figures, shoe 10 will have a front opening for receiving the foot into the shoe. In the embodiment shown in
The embodiment of the shoe 10 of the invention in
In
Preferably, the shoe 10 of the invention will be treated with an antimicrobial finish.
The water shoe of the invention is suitable for manufacture in a variety of sizes for use by children and adults. The amount of strength needed for the material comprising the orthotic and the amount of weight deemed tolerable for the orthotic depends on the size and strength of the wearer and the demands that wearer places on the orthotic, as would be readily understood and determinable by one of ordinary skill in the art.
It will be understood that other shoe configurations may be used to accomplish the principals and advantages of the present invention, and that other materials of construction than described, may be used for the shoe.
While preferred embodiments of the invention have been described, it should be understood that other various changes, adaptations and modifications can be made therein without departing from the spirit of the invention as reflected in the claims.
The invention claims priority from U.S. Provisional Patent Application No. 62/640,038, filed Mar. 8, 2018.
