DETAILED DESCRIPTION OF THE INVENTION

(16) FIGS. 1A, 2A and 3A show multiple views of a static interchangeable strap 10 where any static material (i.e., material that cannot be stretched) suitable for footwear is wrapped around the core 12 of a dumbbell shaped anchor 14 (see FIG. 6). The wrapped material of the strap 10 should sit flush (i.e, aligned to the edge) with the anchor knobs 12. At least one D-ring 16 is mounted to a shoe 20 (see FIG. 8 and FIG. 11) so that the opening of the D-ring 16 extends above the top surface of one flap of an upper of shoe 20, and the strap 10 when inserted in D-ring 16 will be positioned entirely above an outer surface of said shoe 20. The total diameter of knob 12 as well as the portion 11 of the strap 10 wrapped around the anchor 14 will be greater than the inner dimension of the D-ring 16 to provide a secure anchor for the typical force applied to a typical strap closure for footwear. In some embodiments only the knobs 12 of the D-Ring have diameters greater than height of the D-Ring. The tip 18 of the interchangeable strap 10, is secured on the alternate side of the shoe 20 by way of typical hook-and-loop fastener 22a, 22b.

(17) FIGS. 1B, 2B and 3B show an alternate embodiment of the strap 10. In this embodiment the strap 10 is secured in the same manner previously described, however the strap 10 is constructed from a material with dynamic properties (i.e., elastic) to allow the shoe to be more easily slipped on. In this embodiment, the footprint of the typical loop portion 22a of the hook-and-loop fastener 22a, 22b is reduced (when compared to the strap shown in FIGS. 1A, 2A and 3A) on the backside of the strap 10 to allow for full range of dynamic expansion.

(18) The straps 10 are interchangeable to allow straps 10 with differing properties, such as, differing material, color, print and function (static vs. dynamic) to be swapped for one another.

(19) FIG. 4 and FIG. 5 show the preferred D-ring 16. D-ring 16 may be made from multiple materials and may be of varying shapes and sizes, but the preferred material is metal in the form of a rounded rectangle. The D-ring 16 may also be affixed to the shoe 20 in multiple ways to ensure that the opening in D-ring 16 extends above the top surface of one flap of an upper of shoe 20. The preferred method of securing the D-ring 16 to the shoe 20 is to insert the ends 26 through punched holes 28 (see FIG. 8) in the upper portion of shoe 20 and to secure the ends 26 to the backside of the upper material with additional tear-resistant material 30 for optimal durability.

(20) An embodiment of the strap anchor 14 is shown in FIGS. 6 and 7. The anchor 14 may be made from multiple materials such as metal or plastic and the anchor can be of varying shapes and sizes. The preferred material is thermoplastic polyurethane in the form of a dumbbell, wherein the diameter of the knob 12 is greater than the inner diameter 32 of the D-ring 16.

(21) FIG. 9 shows a D-ring 16 affixed to the upper portion of the shoe 20 without any interchangeable strap 10 attached.

(22) FIG. 10 shows the initial engagement of an interchangeable strap 10, with a preferred D-ring 16. The tip 18 of the interchangeable strap 10, is inserted through the bottom facing side of the D-ring 16 and pulled through the D-ring 16 opening and out the upward facing side until further engagement is prevented by the inability of the larger dimensioned anchor 14 to pass through the smaller inner dimension of the D-ring 16 opening.

(23) FIGS. 11 and 12 shows a fully engaged interchangeable strap 10. The tip 18 of the interchangeable strap 10 is secured on the alternate side of the shoe 20 by way of typical hook-and-loop fastener mounted on a top surface of flap 25b.

(24) The removal of the interchangeable strap 10 follows the reverse sequence. In this case, the hook-and-loop fastener 22a, 22b is disengaged from the shoe 20 in typical fashion. Then the anchor 12 is pulled out of the D-ring 16 opening until interchangeable strap 10 is free from the D-ring 16 and fully removed from the shoe 10.

(25) While the foregoing invention has been described with reference to its preferred embodiments various alterations and modifications will occur to those skilled in the art. All such alterations and modifications are intended to fall within the scope of the appended claims.
