For example, a strontium ferrite (SrO.sub.6Fe.sub.2O.sub.3) magnet may be used. As shown in FIG. 4, a (left) shoe sole 407 comprising sole connectors 401, 402, 403, 404, 405, and 406 may be magnets. In one embodiment, these magnets are each north poles of the magnets. However, in another embodiment they may be each be south poles of the magnets. However, the polarity of the magnets for the sole connector is to be the opposite polarity of the magnets on the foot fasteners. These sole connectors also correspond to the locations shown in FIG. 1.

    (30) FIG. 5 also shows an embodiment using magnets instead of Velcro. The magnets that maybe used may be neodymium iron boron (NdFeB), samarium cobalt (SmCo), alnico, and ceramic/ferrite magnets. For example, a strontium ferrite (SrO.sub.6Fe.sub.2O.sub.3) magnet may be used. As shown in FIG. 5, a (right) shoe sole 507 comprising sole connectors 501, 502, 503, 504, 505, and 506 may be magnets. In one embodiment, these magnets are each north poles of the magnets. However, in another embodiment they may be each be south poles of the magnets. However, the polarity of the magnets for the sole connector is to be the opposite polarity of the magnets on the foot fasteners. These sole connectors also correspond to the locations shown in FIG. 2.

    (31) FIG. 6 shows a foot fastener 612 using magnets. If north poles of the magnets are used on the sole, then foot fastener 612 uses south poles of the magnets. If south poles of the magnets are used on the sole, then foot fastener 612 uses the north poles of the magnets. In one preferred embodiment, the soles 402, 502 uses north poles of the magnets and the foot fastener 612 uses south poles of the magnets. Foot fastener 612 uses foot fastener connects 608, 609, and 610. These foot fasteners also correspond to the locations as shown in FIG. 3. Foot fastener 612 may be used in conjunction with the (left) shoe sole 407 or the (right) shoe sole 507 as long as the complementary poles of the magnets are properly selected.

    (32) Foot fasteners can be constructed from an elastic material or inelastic material. In embodiments where the sole connectors are positioned such that the first distance between sole connectors 202 and 205 equals the first distance between sole connectors 202 and 206, and the second distance between sole connectors 201 and 203 equals the second distance between sole connectors 201 and 204, but the first distance does not equal the second distance, foot fasteners constructed from an elastic material are preferred. In this manner, the foot fastener can stretch to accommodate the differences in length between when a shoe is in the sandal mode and when the shoe is in the flip-flop mode. In embodiments where the sole connectors are positioned such that the distance between sole connectors 202 and 205, the distance between sole connectors 202 and 206, the distance between sole connectors 201 and 203, and the distance between sole connectors 201 and 204 are all equal, foot fasteners constructed from an inelastic material can be used. In this manner, the foot fastener does not need to stretch to accommodate the same lengths between when a shoe is in the sandal mode and when the shoe is in the flip-flop mode.

    (33) In general, foot fasteners can be constructed of elastic bands, textile material, plastic, nylon, polyester, leather, woven material, non-woven material, and the like. While the aforementioned distances are described in terms of the right shoe and right sole, the foot fasteners embodiments apply similarly to the left shoe and the left sole. While the aforementioned sole connectors are described with regards to FIG. 2, the sole connectors positioning on the sole applies similarly to FIGS. 1, 4, 5, 8, and 9.

    (34) FIG. 7A shows a cover 712. Cover 712 covers sole 707 such as to hide the sole connectors 701, 702, 703, 704, 705, and 706. Cover 712 can be configured to be either a left cover for the left sole or right cover for the right sole. When it is desired to connect a foot fastener to sole 707, slits 741, 742, 743, 744, 745, and 746 in the cover 712 allows access to sole connectors 701, 702, 703, 705, 705, and 706. The slits can be a hole or cut that allows access to the sole connectors, but also covers the sole connectors when not in use. Thus, when desired to connect foot fasteners to sole connectors, the slits are opened and provide access to the sole connectors. Slits 741, 742, 743, 744, 745, and 746 can be selected to be the same number as there are sole connectors. Slits 741, 742, 743, 744, 745, and 746 can be in the shape of an X, a single cut, a star, two crossing cuts, a circle, a triangle, a hexagon, a square, an oval, and the like.

    (35) FIG. 7B shows a partial view of the cover 712. For example, slit 741 in cover 712 allows access to sole connector 701, while keeping a user's foot from rubbing against the sole connector 701. This would apply similarly for slits 702-706, which cover sole connectors 742-746.

    (36) FIG. 8 is an embodiment showing shoe 807 in a flip-flop mode. Foot fastener 812, with foot fastener connectors 808, 809, and 810, are connected to sole connectors 805, 802, and 806, respectively. When in the flip-flop mode, a toe thong 840 is formed from foot fastener 812, which is capable of being between two adjacent toes, preferably the big toe and the second toe. To help facilitate toe thong 840, foot fastener 812 can include shaping areas 350 and 351 (as shown in FIG. 3C) to shape foot fastener 812 to better fit between the two adjacent toes and provide a wearer with more comfort. Sole connectors 801, 803, and 804 are not used when in the flip-flop mode. While a left shoe is shown, the right shoe would be the same, but reversed.

    (37) FIG. 9 is an embodiment showing shoe 907 in a sandal mode. Foot fastener 912, with foot fastener connectors 908, 909, and 910, are connected to sole connectors 903, 901, and 904, respectively. Sole connectors 902, 905, and 906 are not used when in a sandal mode. While a right shoe is shown in FIG. 9, the left shoe would be the same, but reversed. While in a sandal mode, foot fastener 912 does not form a toe thong.

    (38) For example, when desired to use the shoe in sandal mode, left foot fastener 311 is connected to sole 107 using foot fastener connector 308 to sole connector 101; foot fastener connector 309 to sole connector 103; and foot fastener connector 310 to sole connector 104. Right foot fastener 321 is connected to sole 207 using foot fastener connector 328 to sole connector 201; foot fastener connector 329 to sole connector 203; and foot fastener connector 330 to sole connector 204.

    (39) When desiring to switch to sandal mode, the foot fasteners 311, 321 can be removed and then connected to soles 107, 207 as shown in FIG. 9. When desiring to switch to flip-flop mode, the foot fasteners 311, 321 can be removed and then connected to soles 107, 207 as shown in FIG. 8.

    (40) FIG. 10A shows an embodiment according to the present disclosure using a slide feature showing a shoe 1007 in a flip-flop mode. Here, the slide connectors are in the position shown for the flip-flop mode. Toe slide path 1070 is where foot fastener 1021, which comprises a slide connector 1002, slides across the sole of shoe 1007. Once the slide connector is in a desired place, it can lock in such that it will not move without excessive force. Slide connector 1002 can be made of any suitable material such as plastic, rubber, metal, or the like. Slide connector 1005 slides along a right slide path 1072. Slide connector 1006 slides along a diagonal slide path 1071. By using the slide connectors, the shoe can be converted between a sandal mode and a flip-flip mode without having to remove foot fastener 1021. When desired to switch modes, the slide connectors can be moved to the alternative position, locking in place at their respective positions. For example, when switching from a flip-flop mode to a sandal mode, the slide connectors move from positions show in FIG. 10A to FIG. 10B.

    (41) FIG. 10B shows an embodiment according to the present disclosure using the slide feature showing the shoe 1007 in a sandal mode. Here, the slide connectors are in the position shown for the sandal mode. Toe slide path 1070 is where foot fastener 1021, which comprises a slide connector 1002, slides across the sole of shoe 1007. Slide connector 1005 slides along right slide path 1072. Slide connector 1006 slide along diagonal slide path 1071.

    (42) Foot fastener 1021 can also be adjustable in length, using for example a buckle, Velcro, cam buckle, D-rings, or the like. Foot fastener 1021 could also be made of an elastic material that allows it to stretch to different sizes. This can allow for different feet sizes to fit within the shoe. In one embodiment, foot fastener 1021 when used in flip-flop mode is half the size of foot fastener 1021 when used in sandal mode, and thus when used in flip-flop mode, the foot fastener 1021 is double backed.
