This present application hereby incorporates by reference U.S. Patent Application Ser. No. 13/323,044, filed on December 12, 2011, U.S. Patent Application Ser. No. 13/219,828, filed on Aug. 29, 2011, and U.S. Provisional Patent Application Ser. No. 61/385,055, filed on Sep. 21, 2010 in their entirety. Exemplary embodiments of the disclosed subject matter are described below, with reference to the figures, for purposes of illustration, and not limitation.

Fig. 1A shows a top view of an apparatus 10 which in one or more embodiments may be characterized as a combination flip flop and slipper. The apparatus 10 includes a base 14, a covering 12, a strap 16, and portions 18 and 20, and a surface 22. Fig. IB shows a top view of the covering 12 and the base 14 without the strap 16 and without the portions 18 and 20.

Fig. 1C shows a top view of a foot 30 of an individual placed on top of the apparatus 10 so that the foot 30 rests on top of the covering 12 and not underneath the covering 12. Fig. ID shows a top view of the foot 30 of an individual with toes 32, 34, and 36, at least partially inserted underneath the covering 12, so they are between the covering 12 and the base 14.

The covering 12 may be a stretchy fabric which is securely attached to the perimeter edge 14a of the base 14 or flip-flop foot bed. This can be achieved by fusion, sawing or sandwiching between the inner and outer sole of the base 14 or flip- flop foot bed. One can use the apparatus 10, also called a "Slip Flop" as a regular flip-flop by simply placing your feet in the apparatus 10, under the strap 16 and on top of the covering or fabric 12 as shown partially in Fig. 1C. In use, the foot 30 would be inserted further under the strap 16 in order to wear the apparatus 10 on the foot 30.

However, the covering 12, which may be a stretchy fabric, allows a person to slip their foot 30 under the covering 12 as shown partially in Fig. ID and under the covering 12 to use the apparatus 10 as a slipper. In at least one embodiment, the covering 12 is a fabric which stretches and hugs around the foot 30 to keep the foot 30 warm when the foot 30 is fully inserted underneath the covering 12. Once the foot 30 is removed the stretchy fabric of the covering 12, in at least one embodiment, returns back to its flat position at the surface of the base or foot bed 14 of the flip-flop or apparatus 10. The dual function of the apparatus 10 or "Slip Flop" can be used alternatively as the ambient temperature changes. In at least one embodiment, any stretchy material, which has the quality to be elastic enough to stretch to two hundred percent of its original shape (i.e. double in size) and return to one hundred percent of its original shape (i.e. its original size) can be used for the covering 12. Polyester with more than eighteen percent of Spandex (trademarked) may be used for the covering 12. The foot bed surface or surface of base 14, in at least one embodiment, should be textured in such a manner as to keep the fabric or covering 12 from sliding, while walking. The base 14 or sole 14 may be made of fully molded foot bed ethylene-vinyl acetate (EVA) material for comfort. Possibly a "sandwich" construction with tougher outsole and softer insole material may be used for base 14. The covering 12 may have a fabric edge 12a, at the opening to slide foot 30 in. The fabric edge 12a, in at least one embodiment, is strong and elastic. The fabric edge 12a may be thin and comfortable to step on and walk, such as when a foot 30 is placed on top of the covering 30. The portion 20 may be a strap "pole" and may be finished as a "button hole" or with a delicate grommet. The portion 20 or strap "pole" can be decorative, such as a jewelry style.

The apparatus 10 of Fig. 1A can be applied to or in combination with the water proof or aqua embodiment of Fig. 5 or Figs. 6A-6D, which will be described.

Fig. 2A shows a side view of an apparatus 100 with a base 114 and a strap 116. Fig. 2B shows a side view of an apparatus 130. The apparatus 130 can be inserted into the apparatus 100 in order to provide a slipper and flip-flop combination. The apparatus 130 includes a covering 132 similar to the covering 12 of Fig. 1A. The apparatus 100 includes a base 114 similar to the base 14 of Fig. 1A. In the Figs. 2A- B embodiment, an apparatus identical to or similar to 130, except for color or some pictorial design aspect may be inserted into the apparatus 100 instead of apparatus 130. In this manner, the "Slip Flop" user can switch different designs and different colors.

In addition, the apparatus 130 may include a base 134 which may have a Velcro (trademarked) hooks or loops material on the bottom 134a of the base 134. The apparatus 100 may include a top 114a which may have a mating hooks or loop material, which mates with the material on the bottom 134a to hold the apparatus 130 on the apparatus 100.

The apparatus 130 or insert can be made of a variety of materials such as a sock-like softer material or a harder material like felt or sheepskin. This alternative can be applied in a full sandal where "Velcro" (trademarked) may not be required. Three basic shapes of the slipper insert, such as apparatus 130, may be possible in one or more embodiments: (a) one-third coverage by covering 132, which would cover toes only and end at the straps; (b) two-thirds coverage, like a typical slipper, and (c) full coverage, like a slipper with heel covered or any sandal type footwear. There are an endless variety of color and design for the apparatus 130. The

Figs. 2A-B embodiment can be applied to or in combination with the water proof or aqua embodiment of Fig. 5 or Figs. 6A-6D, which will be described.

Fig. 3D shows a top view of the apparatus or sandal 200. The apparatus or slipper 250 may have a base 254 having a bottom surface 254a which may include a hooks and/or loops material. The hooks and loops material of 254a may connect and mate with a mating hooks and/or loops material of surface 214a to attach the apparatus 250 with the sandal 200.

The apparatus or sandal 200 may include Velcro (trademarked) (hook and/or loops) sections 201a, 201b, and 201c, shown in Fig. 3D. The apparatus or slipper 250 may include Velcro (trademarked) sections 255a, 255b, and 255c, which may mate with, align with, and may be the same shape (although though shown roughly in Figs. 3C and 3D), as their mating sections 201a, 201b, and 201c, when the foot 270 with the apparatus 250 is placed in the apparatus 200 as shown in Fig. 3A.

The embodiment of Figs. 3A-D may be applied to a sandal instead of a flip- flop and can be applied to any design of sandals, such as ladies' or men's.

Fig. 4A shows a top view of an apparatus 300 in combination with an apparatus 350. Fig. 4B shows a side view of the apparatus 300 without the apparatus 350. Fig. 4C shows a side view of the apparatus 300 in combination with the apparatus 350. The combination of the apparatus 300 and 350, shown in Fig. 4A and 4C, may be a convertible sandal or sandal and slipper in one. The apparatus 300 may be a sandal and the apparatus 350 may be a slipper. The apparatus 300 may be or may be replaced by a sandal with a buckled strap or ankle strap, ladies' or mens'. The apparatus 300 may include a strap 316 and a base 314. The apparatus 300 may be made of materials as for flip-flops or sandals previously described in Figs. 1A, 10, ID, 2A, and 3B. The apparatus 350 may be made of materials as for slippers previously described for Figs. IB, 2B, and 3B.

Fig. 5 shows a side view of an apparatus or sandal 400 and an apparatus or slipper 450, along with part of a person's hand 490. The combination of the apparatus 400 and the apparatus 450 in Fig. 5 may be called a convertible aqua sandal. The apparatus or slipper 450 may be made of a water proof stretchy aqua fabric. The apparatus or slipper 450 may be securely attached to the perimeter edge 414a of the apparatus 400 base or foot bed 414. The apparatus 400 may also include a plurality of straps 416. The apparatus or slipper 450 can be attached to the apparatus or sandal 400 by fusion, sawing or sandwiching between the inner and outer sole of the foot bed or base 414. The base 414 may have an outer sole, portion or surface 418, and an inner sole, portion or surface 420. The outer sole, portion or surface 418 may be made of a hard material, while the inner sole 420 may be made of a soft material. The base 414 may include an inner material between the inner sole 420 and the outer sole 418, and the inner material of the base 414 may be made of EVA (ethylene-vinyl acetate) polymer or rubber foam.

An individual can use the combination of apparatus 400 and 450, also called a "Slip Flop", as a regular flip-flop, by simply placing the individual's foot in the apparatus 400 (under the straps 416, and on top of the base 414) and on top of the apparatus or aqua (water-proof) fabric 450. However, the stretchy aqua fabric or apparatus 450 on the foot bed or base 414 allows a person to slip their foot into the apparatus 450 or slipper and under the fabric to use it as an aqua shoe/slipper. The fabric of apparatus 450 stretches and hugs around an individual's foot to keep a foot warm in the cold weather. Once the foot is removed the stretchy fabric of the apparatus 450 returns back to its flat position at the surface or base 414 of the foot bed of the flip-flop or apparatus 400. The combination of the apparatus 400 and the apparatus 450 is a type of water footwear that will protect a person's foot from painful surfaces, keep the person's foot warm in cold water, and provide support for feet.

Additionally and/or alternatively, in certain embodiments, the apparatus 300 can include a heel component 970 to provide additional support for a person's foot 30 when inserted into either the first or second opening.

In accordance with another aspect of the disclosed subject matter, and with reference to Figs. 10A-E, a shoe apparatus 1000 can include a base 1014 and a strap component 1016. The base 1014 can include a perimeter edge 1014a and a sole with a forefront portion 1020 and a rearfoot portion 1030. The strap component 1016 can include a center connector 1018, two edges 1017a and 1017b, and an expandable material 1016a. The center connector 1018 can be attached to the forefront portion 1020 of the base 1014. The two edges 1017a and 1017b can be attached to a left side and a right side of the perimeter edge 1014a, respectively, thereby forming an opening for receiving a person's foot between the strap 1016 and the sole of the base 1014. The expandable material 1016a of the strap component 1016 can be adapted to convert from a contracted state, as illustrated in Fig. 10B, to an expanded state, as illustrated in Fig. 10E. In this manner, the apparatus 1000 can be used as a sandal when the expandable material 1016a is in a contracted state and can be used as a slipper when the expandable material 1016a is in an expanded state. That is, for example, the expandable material 1016a can form a cover component that forms a cavity between the forefront portion 1020 of the sole and the strap component 1016 suitable for receiving a person's foot when the expandable material 1016a is in the expanded state.

For example, in certain embodiments, a first edge of the expandable material 1016a can be attached to a first edge of the strap component 1016, and a second edge of the expandable material 1016a can be removably affixed or attached to a second edge of the strap component 1016 in the contracted state. The second edge of the expandable material 1016a can be affixed to the second edge of the strap component 1016, for example, by Velcro, snaps, buttons, clasps, or other suitable technique known in the art. When an individual desires to convert the sandal depicted in Fig. 10B into a slipper as depicted by Fig. 10E, the second edge of the expandable material 1016a can be detached from the second edge of the strap component 1016, expanded toward the perimeter edge 1014a of the forefront portion 1020 of the base 1014, and attached to the perimeter edge 1014 along the forefront portion 1020 of the base.
