Description
CONVERTIBLE SHOE
Technical Field
The present invention relates generally to the field of footwear. More specifically the present invention relates to a convertible shoe provided with variety of straps, wraps and snaps to permit customizing the shoe to various tastes, clothing combinations and occasions, permitting the purchaser to design and reconfigure his or her own shoe style and to have a new look whenever desired. The convertible shoe specifically includes a shoe base having shoe base surfaces fitted with fastener means to which any of a variety of interchangeable shoe accessories hereinafter referred to as shoe parts are removably attached to selectively produce a desired shoe configuration and color. Any suitable fastener means may be used, but one preferred fastener means is an array of first snap fastener halves secured to the base surfaces, with opposing and connecting second snap fastener halves secured to the shoe parts. Another suitable fastener means is the hook portion or loop portion of hook and loop fastener sheets also commercially known as VELCRO™ secured to the shoe base surfaces, which removably connect to an opposing loop portion or hook portion of hook and loop fastener sheets on the shoe parts. The hook and loop fastener sheets are removably attached to the elements making up the shoe so that they can be replaced with new hook and loop fastener sheets when they become worn. The resulting assembled shoe may be a dress shoe, clog, boot, sandal or virtually any other type of shoe.
One version of the shoe base is an elongate panel having the shape and size of a shoe sole for the given wearer, and the base surfaces to which fastener means are secured include a longitudinal panel side surfaces, panel front and rear surfaces and panel top and bottom surfaces, respectively. The shoe parts include several shoe top structures of various configurations shaped to wrap over the top of a wearer foot and downwardly to connect at their lower ends to fastener means on the shoe base, and preferably to the longitudinal panel side surfaces, panel rear surface and in some instances to peripheral portions of the panel top and bottom surfaces. Since the shoe top structures may have very different configurations from each other, they connect to the shoe base at a variety of different locations. For this reason, the fastening means are provided over broad areas of the shoe base surfaces.
The shoe parts further include several shoe bottom structures of various configurations including a sole portion connected to a heel portion. The panel and the bottom
structure are permanently interconnected or may be a single integral part. In either instance, a heel cover sheet for changing the color or style of the shoe also is optionally provided having heel cover fastener means which attach to base fastener means on the heel portion and bottom or sole surfaces.
There have long been many varieties and configurations of shoes. A limitation inherent in shoes has been that whatever configuration they initially have cannot be altered so that only one permanent style is provided.

The hook and loop fastener sheets 46 and 48 are removably attached to the elements making up the convertible shoe 10 so that they can be replaced with new hook and loop fastener sheets 46 and 38 when they become worn.
One version of the shoe base 20 is an elongate panel 30 having the shape and size of a shoe sole for the given wearer, and the base surfaces S to which fastener means 40 are secured include a longitudinal panel side surfaces 32 and 34, panel front and rear surfaces 30A and 3OB and panel top and bottom surfaces 36 and 38, respectively. The shoe parts P include several shoe top structures 60 of various configurations shaped to wrap over the top of a wearer foot and downwardly to connect at their lower ends 62 to fastener means 40 on the shoe base 20, and preferably to the longitudinal panel side surfaces 32 and 34, panel rear surface 30A, bottom surface and in some instances to peripheral portions of the panel top surface 36. Since the shoe top structures 60 may have very different configurations from each other, they connect to the shoe base 20 at a variety of different locations. For this reason, the
fastening means 40 are provided over broad areas of the shoe base surfaces S.
The shoe parts 10 further include several shoe bottom structures 80 of various configurations including a sole portion 82 connected to a heel portion 84. The heel portion 84 is permanently connected to the sole portion 82 or are integral. One version of the sole portion 82 has spikes or cleats 88, so that the user can for example change sole portions 82 to move from the office to the golf course. Alternatively the panel 30 and the bottom structure 80 may be permanently interconnected or may be a single integral part. A foot bed 92 optionally is provided for fastening onto the panel top surface 36 to increase wearer height, and the foot bed 92 may be provided in any of a variety of colors and several may be stacked on a sole portion 82 to give the wearer greater height. See FIGURES 2-2B. The foot bed 92 preferably includes foot bed ports 64 for passing shoe top structure lower ends 62 so that the lower ends 62 can be fastened to the top surface of the elongate panel 30, or to the lower surface of the foot bed 92, or to the sides or bottom of the elongate panel 30. See FIGURES 8 and 9. The fasteners such as snap fastener halves 42 may be mounted on a lower end cross member 66.
The applicant notes that: one version is an arch support system allowing wearer to change various sized arches or supports, and customize for comfort or medical reasons. The changeable arches or supports can be fastened to the top surfaces and side surfaces of foot bed 92, or passed through foot bed ports 64 and fastened to the bottom surfaces of foot bed 92, or to the top surfaces and side surfaces of elongate panel 30.
Thus, in accordance with the present invention, a shoe top structure 60 can be fastened with snap fastener halves 42 and 44 or with hook and loop fastener portions 46 and 48, or with virtually any other fastener means 40 to absolutely any surface of the foot bed 92, or to absolutely any surface S of the shoe base 20 such as an elongate panel 30, or to absolutely any surface of the sole portion 82 including any surface of the heel portion 84, or to any combination of these. This is one way in which the present convertible shoe 10 is fully versatile.
A fabric heel cover sheet 90 may be provided for changing the color or style of the shoe 10. The fabric heel cover sheet 90 has heel cover fastener means 40 which attach to base fastener means 40 on heel portion 84. The heel cover sheet 90 may wrap around and cover the rear and side surfaces of the heel portion 84, as shown in FIGURES 3 and 4 or may wrap entirely around and cover the heel portion 84 rear, side and front surfaces. The heel cover sheet 90 still alternatively may take the form of a tube or sleeve sized as shown in FIGURE 5
to fit snugly over the heel portion 84 from the heel portion 84 lower end, and is optionally elastic to accomplish such a snug fit. The fabric heel cover sheet 90 may be formed of thin material to follow and duplicate the shape of the heel portion 84, or may be formed of thicker material to define a shape different from that of the existing heel portion 84.
An alternative to the tubular fabric heel cover sheet 90 is a rigid heel cover 94 or heel cover block which has a substantially fixed solid form defining a hell portion 84 shape which has a heel receiving passageway 96 opening into its rigid heel cover 94 upper surface for receiving the existing shoe heel portion 84 and then fastening to the existing heel portion 84 or sole portion 82 or both. The rigid heel cover 94 optionally has a flexible cover sheet 94A permanently fastened to its outer surface which extends above the rigid or block segment of the heel cover 94 and has inwardly directed fasteners such as fastener halves 42 and 44 for fastening to the existing sole portion 82 and heel portion 84. See FIGURE 11.
The outward surfaces of the snap fasteners 42 and 44 may be adorned with gemstones or other decorative element.
While the invention has been described, disclosed, illustrated and shown in various terms or certain embodiments or modifications which it has assumed in practice, the scope of the invention is not intended to be, nor should it be deemed to be, limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved especially as they fall within the breadth and scope of the claims here appended.
