Abstract

A shoe system including a shoe upper with a bottom side having an aperture extending to a cavity. The shoe system also includes a selectively removable outsole which includes a bottom for contacting the ground, and a top for engaging with the bottom of the shoe upper. The top side of the outsole further includes a projection which is sized and shaped to extend through the aperture and into the cavity when the outsole is in a first orientation, which is misaligned with respect to the shoe upper. The projection is also sized and shaped to fit within the cavity but no longer back through the aperture when the outsole is in a second orientation, which is aligned with respect to the shoe upper. In the second orientation, the projection within said cavity prevents disengagement of the outsole from the shoe upper.

First claim

The invention claimed is:

1. A shoe system comprising: a shoe upper including a bottom side, said shoe upper including: at least one elongated slot on the bottom side; a depressible button; and a recess on the bottom side, said recess including a cover, said cover further including an aperture, said aperture defining a smooth opening in the cover leading into the recess; a removable outsole re-engageable with the shoe upper, an upper side of said outsole including: at least one elongated flange sized and shaped to engage the at least one slot in said shoe upper; a heel cup including a hole, said hole for accepting the depressible button when said button is not depressed; a key lock sized and shaped to extend through the aperture in the cover, into the recess in the shoe upper; wherein said recess and key lock are located proximate an arch portion of the shoe upper and outsole, respectively; wherein said key lock is positioned on said outsole to fit through the aperture when said outsole is misaligned with said shoe upper; wherein upon positioning the key lock through the aperture and into the recess, and rotating the outsole into alignment with the shoe upper, said rotation of the outsole causes: said key lock to rotate within the recess such that the key lock does not fit back out through the aperture in the cover; said at least one flange to slide into and engage with the at least one slot; and said heel cup to slide over the button such that the button fits within the hole of the heel cup.

2. The shoe system of claim 1 wherein the at least one slot has a generally T-shaped cross section.

3. The shoe system of claim 1 wherein the at least one slot includes at least two slots, with at least one proximate a heel portion of the shoe upper and at least another proximate a ball portion of the shoe upper.

4. The shoe system of claim 1 wherein each of said at least one slot is radiused about a center point of rotation of the outsole with respect to the shoe upper.

5. The shoe system of claim 1 wherein said aperture and said key lock are elongate.

6. The shoe system of claim 1 further including:
a tab extending from one side of said outsole, said tab extending upwardly toward said shoe upper; and
a notch in one side of said shoe upper for accepting the tab when said outsole and said shoe upper are engaged with one another and aligned.

7. A shoe system comprising: a shoe upper including a bottom side, said bottom side including an aperture extending to a cavity and at least one elongate slot; a removable and re-engageable outsole including a bottom for contacting the ground, and a top for engaging with the bottom of said shoe upper, the top side of said outsole further including a projection; at least one elongate flange extending from the outsole, said flange being receivable within a respective one of said at least one slots such that said flange slideably dovetails with said slot to further secure the outsole to the shoe upper; wherein each of said at least one slot and its corresponding flange are radiused about a center point of rotation of the outsole with respect to the shoe upper; wherein the center point of rotation is located proximate an arch portion of the shoe upper and outsole, wherein said projection is sized and shaped to extend through said aperture into said cavity when said outsole is in a first orientation with respect to said shoe upper; wherein said projection is sized and shaped to fit within said cavity but no longer through said aperture when said outsole is in a second orientation with respect to said shoe upper; wherein in said second orientation, the projection within said cavity prevents disengagement of said outsole from said shoe upper; and wherein said second orientation of said outsole is in general alignment with said upper.

8. The shoe system of claim 7 further including:
a tab extending from one side of said outsole, said tab extending upwardly toward said shoe upper; and
a notch in one side of said shoe upper for accepting the tab when said outsole is in said second orientation with respect to the shoe upper.

9. The shoe system of claim 7 further including:
a selectively depressible button positioned at a heel portion of said shoe upper;
a heel cup extending up from the top of the outsole, said heel cup including a hole for accepting the depressible button when said outsole is in said second orientation.

10. The shoe system of claim 7 wherein the at least one slot has a generally T-shaped cross section.

11. The shoe system of claim 7 wherein the at least one slot includes at least two slots, with at least one proximate a heel portion of the shoe upper and at least another proximate a ball portion of the shoe upper.

12. The shoe system of claim 1 wherein said aperture and said projection are elongate.
