Removable footwear traction plate
View Patent ↗A traction plate and a method of use for a shoe. The traction plate is removably attachable to the outsole of a shoe to provide traction on a surface for a shoe wearer. The plate includes a flange with one or more surface-engaging elements on one face. The plate also includes two or more shoe-coupling elements. The shoe-coupling elements are inserted into corresponding receptacles in a shoe-outsole and then rotated to affix the plate to the shoe. The shoe-coupling elements may be captively attached to the plate flange or attachable to the shoe receptacle with a rotation of no more than one full revolution.

providing a shoe outsole including a plurality of receptacles and a removable traction plate, the traction plate including a shoe-coupling element for removably attaching the traction plate to at least one of the first and second receptacles by a rotation of the shoe-coupling element, the shoe-coupling element being configured to be captively attached to the traction plate such that (i) the shoe-coupling element passes through the traction plate, (ii) the shoe-coupling element is rotatable within and with respect to the traction plate when the shoe-coupling element is captively attached to the traction plate and (iii) the traction plate retains the shoe-coupling element when the shoe-coupling element is detached from the shoe and the traction plate is rotated about any axis,
inserting the shoe-coupling element into at least one of the first and second receptacles; and
rotating the shoe-coupling element to affix the traction plate to the outsole such that the traction plate does not rotate with respect to the shoe.
2. The method according to claim 1 wherein the shoe-coupling element is rotated no more than 360 degrees to affix the traction plate to the outsole.
3. The method according to claim 1 wherein the shoe-coupling element is rotated no more than 270 degrees to affix the traction plate to the outsole.
4. The method according to claim 1 wherein the shoe-coupling element is rotated no more than 180 degrees to affix the traction plate to the outsole.
5. The method according to claim 1 wherein the shoe-coupling element is rotated no more than 120 degrees to affix the traction plate to the outsole.
6. The method according to claim 1 wherein the shoe outsole initially contains a plurality of installed cleats, further including first removing each cleat installed in the outsole area to be covered by the plate.
7. A removable footwear traction plate for attaching to footwear having first and second receptacles, the traction plate comprising:
a traction flange including opposing upper and lower faces and including on the lower face at least one traction protrusion for providing friction with the ground; and
a shoe-coupling element for removably attaching the traction flange to at least one of the first and second receptacles by a rotation such that the flange does not rotate with respect to the shoe, wherein the rotation of the shoe-coupling element is not more than 360 degrees,
wherein the shoe-coupling element is captively attached to the traction flange such that (i) the shoe-coupling element passes through the flange, (ii) the shoe-coupling element is rotatable within and with respect to the flange when the shoe-coupling element is captively attached to the flange and (iii) the flange retains the shoe-coupling element when the shoe-coupling element is detached from the shoe and the flange is rotated about any axis.
8. The traction plate according to claim 7 , wherein the shoe-coupling element is removably attachable to at least one of the first and second receptacles by a rotation of not more than 180 degrees.
9. The traction plate according to claim 7 , wherein the shoe-coupling element is removably attachable to at least one of the first and second receptacle by a rotation of not more than 120 degrees.
10. The traction plate according to claim 7 , wherein the flange includes an edge and a bearing portion remote from the edge, the bearing portion bearing a majority of the weight of a user placed on the traction plate.
11. The traction plate according to claim 7 , wherein the flange includes an edge and the at least one traction protrusion extends outwardly beyond the edge of the flange.
12. The traction plate according to claim 7 , wherein the flange includes a flex-line.
13. The traction plate according to claim 12 , wherein the flange is rigid on one side of the flex-line.
14. The traction plate according to claim 7 further including a wear indicator.
15. A removable footwear traction plate for attaching to footwear having first and second receptacles, the traction plate comprising:
a traction flange including opposing upper and lower faces and including on the lower face at least one traction protrusion for providing friction with the ground; and
a shoe-coupling element for removably attaching the traction flange to at least one of the first and second receptacles by a rotation such that the flange does not rotate with respect to the shoe wherein the rotation of the shoe-coupling element is not more than 360 degrees,
wherein, when the shoe-coupling element is detached from the shoe, the shoe-coupling element being captively attached to the traction flange such that the flange retains the shoe-coupling element, and the shoe-coupling element being rotatable with respect to the traction flange about any axis when the shoe-coupling element is captively attached to the flange.
16. The traction plate according to claim 15 , wherein the shoe-coupling element is removably attachable to at least one of the first and second receptacles by a rotation of not more than 180 degrees.
17. The traction plate according to claim 15 , wherein the shoe-coupling element is removably attachable to at least one of the first and second receptacle by a rotation of not more than 120 degrees.
18. The traction plate according to claim 15 , wherein the flange includes an edge and a bearing portion remote from the edge, the bearing portion bearing a majority of the weight of a user placed on the traction plate.
19. The traction plate according to claim 15 , wherein the flange includes an edge and the at least one traction protrusion extends outwardly beyond the edge of the flange.
20. The traction plate according to claim 15 , wherein the flange includes a flex-line.
21. The traction plate according to claim 20 , wherein the flange is rigid on one side of the flex-line.
22. A method for attaching a traction plate to a shoe having at least one receptacle, the method comprising:
providing a shoe outsole including at least one receptacle and a removable traction plate, the traction plate including a shoe-coupling element for removably attaching the traction plate to at least one receptacle, the shoe-coupling element being configured to captively attach to the traction plate such that the traction plate retains the shoe-coupling element when the shoe-coupling element is detached from the shoe and the traction plate is rotated about any axis, and the shoe-coupling element is rotatable with respect to the traction plate,
inserting the shoe-coupling element into at least one receptacle; and
affixing the traction plate to the outsole such that the traction plate does not rotate with respect to the shoe.
