and a heel comprising a threaded shaft upwardly extending therefrom, wherein the rigid plate comprises a threaded barrel comprising a lower open end and an upper closed end opposite therefrom, and wherein the heel is removably attached to the upper based on the threaded shaft threading into the threaded barrel from the lower open end to the upper closed end, and wherein the rigid plate extends over the heel when the heel is removably attached to the upper, and wherein the rigid plate extends past the heel towards the toe portion along the outersole. ## Claims ### Claim 1 A shoe comprising: an upper comprising an outersole, a toe portion, and a rigid plate; and a heel comprising a threaded shaft upwardly extending therefrom, wherein the rigid plate defines a threaded barrel therein, wherein the rigid plate and the threaded barrel form a single continuous piece formed from a same material, wherein the threaded barrel comprising a lower open end and an upper closed end opposite therefrom, and wherein the heel is removably attached to the upper based on the threaded shaft threading into the threaded barrel from the lower open end to the upper closed end, and wherein the rigid plate is continuous and extends over the heel when the heel is removably attached to the upper, and where the rigid plate extends past the heel towards the toe portion along the outersole. ### Claim 2 (depends on 1) The shoe of claim 1, wherein the upper comprises an upper edge and a flexible portion extending from the upper edge in a downward direction toward the rigid plate. ### Claim 3 (depends on 1) The shoe of claim 1, wherein the upper comprises an arch and a midsole, and wherein the rigid plate mirrors the arch and resides between the midsole and the outersole. ### Claim 4 (depends on 1) The shoe of claim 1, wherein the upper further comprising an uppermost edge that comprises a supporting stitching that allows the upper to deform when worn with the heel removably attached thereto. ### Claim 5 (depends on 4) The shoe of claim 4, wherein the supporting stitching is an elastic stitching. ### Claim 6 (depends on 1) The shoe of claim 1, wherein the heel is a high heel. ### Claim 7 (depends on 1) The shoe of claim 1, wherein the heel is a flat heel. ### Claim 8 (depends on 1) The shoe of claim 1, wherein the heel is of a mid-height. ### Claim 9 (depends on 1) The shoe of claim 1, wherein the heel is a pyramid heel, a stiletto, a spike heel, a kitten heel, or a block heel. ### Claim 10 (depends on 1) The shoe of claim 1, wherein the shoe is a boot, a mule, a slingback, a pump, or a slipper. ### Claim 11 A shoe comprising: an upper that comprises an upper edge, an arch, a midsole, a toe portion, an outersole, and a rigid plate, wherein the rigid plate defines a threaded barrel therein, wherein the threaded barrel comprising a lower open end and an upper closed end opposite therefrom, wherein the rigid plate and the threaded barrel form a single continuous piece formed from a same material; and a heel comprising a threaded shaft upwardly extending therefrom, wherein the heel is removably attached to the upper based on the threaded shaft threading into the threaded barrel from the lower open end to the upper closed end, wherein the rigid plate is continuous and extends over the heel when the heel is removably attached to the upper, wherein the rigid plate extends past the heel towards the toe portion along the outersole, and wherein the upper edge is reinforced with a support stitching that prevents the upper edge from deforming when the upper is worn with the heel removably attached thereto. ### Claim 12 (depends on 2) The shoe of claim 2 wherein the flexible portion comprises a V shaped notch filled with a flexible material. ### Claim 13 A shoe that is convertible between a heel mode and a flat mode, the shoe comprising: an upper portion comprising an arch, a toe portion, a midsole, an outersole, and a rigid plate, wherein the rigid plate defines a threaded barrel therein, wherein the threaded barrel comprising a lower open end and an upper closed end opposite therefrom; wherein the rigid plate and the threaded barrel form a single continuous piece formed from a same material, and a heel, wherein the upper portion is configured for wearing without the heel; and a threaded barrel plug upwardly extending from the heel, wherein the heel is removably attached to the upper portion based on the threaded barrel plug threading into the threaded barrel from the lower open end to the upper closed end, wherein the rigid plate is continuous and extends over the heel when the heel is removably attached to the upper portion, wherein the rigid plate extends past the heel towards the toe portion along the outersole. ### Claim 14 (depends on 11) The shoe of claim 11, further comprising: a flexible portion formed into the upper portion that extends from an upper edge downwardly toward the rigid plate and allows the upper portion to flex when the upper portion is worn with the heel removably attached thereto. ### Claim 15 (depends on 11) The shoe of claim 11, wherein the heel is a flat heel. ### Claim 16 (depends on 11) The shoe of claim 11, wherein the heel is of a mid-height. ### Claim 17 (depends on 11) The shoe of claim 11, wherein the heel is a pyramid heel, a stiletto heel, a spike heel, a kitten heel, or a block heel. ### Claim 18 (depends on 12) The shoe of claim 12, wherein the flexible material comprises an elastic portion. ### Claim 19 A shoe comprising: an upper that comprises an upper edge, an arch, a toe portion, a midsole, an outersole, and a rigid plate, wherein the rigid plate comprises a threaded shaft downwardly extending therefrom, wherein the threaded shaft and the rigid plate are a single continuous piece formed from a same material; and a heel comprising a threaded barrel, wherein the threaded barrel comprising a lower closed end and an upper open end opposite therefrom, wherein the heel is removably attached to the upper based on the threaded shaft threading into the threaded barrel from the upper open end to the lower closed end, and wherein the upper edge is reinforced with a support stitching that prevents the upper edge from deforming when the upper is worn with the heel removably attached thereto, wherein the rigid plate extends over the heel when the heel is removably attached to the upper, wherein the rigid plate extends past the heel towards the toe portion along the outersole. ### Claim 20 (depends on 1) The shoe of claim 1, wherein the upper comprises an arch, wherein the rigid plate extends from over the heel along the arch toward the toe portion as one continuous piece.
