Traction cleat system for an athletic shoe
View Patent ↗A traction cleat system for an athletic shoe is disclosed. The system includes an elongated receptacle that receives a cleat strip. The elongated receptacle may be a channel or notch formed into the sole of the shoe. In one embodiment, the cleat strip includes an elongated, flexible hub, a cleat connector, and traction elements depending from the hub. The cleat strip is removable from the receptacle, permitting easy replacement of the cleat assembly when the traction elements become worn.

a cleat connector,
an elongated hub having a substantially semicircular cross section defining generally rounded, ground-facing surface and a generally flat, shoe-facing surface, and
a plurality of traction elements depending from and spaced longitudinally along the hub,
wherein shoe-facing surface of the hub is configured to cover the receptacle when the cleat assembly is coupled to the receptacle to prevent debris from entering the receptacle.
2. The traction cleat system of claim 1 , wherein:
at least a portion of the receptacle extends along the sole longitudinal dimension; and
the elongated receptacle comprises an arcuate portion that curves laterally as it extends along the sole longitudinal dimension.
3. The traction cleat system of claim 2 , wherein the elongated hub is configured to bend such that it contours to the curves of the receptacle.
4. The traction cleat system of claim 1 , wherein the elongated receptacle comprises an asymmetrical cavity configured to receive the cleat assembly in a predetermined orientation and to align the traction elements in a predetermined orientation with respect to the sole.
5. The traction cleat system of claim 1 , wherein:
the elongated hub comprises a central hub axis that divides the hub into a first hub quadrant and a second hub quadrant; and
the plurality of traction elements comprises:
a first traction element depending from the first hub quadrant, and
a second traction element depending from the second hub quadrant.
6. The traction cleat system of claim 1 , wherein:
the elongated hub defines a longitudinal hub axis; and
the elongated hub further comprises flex points that enable lateral bending of the hub along the longitudinal hub axis.
7. The traction cleat system of claim 1 , wherein:
the sole includes a forward sole portion, an intermediate sole portion, and a rear sole portion; and
the elongated receptacle extends from the forward sole portion to the rear sole portion.
8. The traction cleat system of claim 1 , wherein the receptacle comprises a cavity formed into the sole.
9. An athletic shoe comprising:
a sole including a shoe-facing surface and a ground-facing surface that cooperate to define sole peripheral edge;
an elongated receptacle for a traction cleat, wherein the receptacle comprises an arcuate portion that curves as the receptacle extends along the sole; and
a cleat assembly coupled to the receptacle, the cleat assembly comprising:
an elongated hub comprising substantially semicircular cross section defining generally rounded, ground-facing surface and a generally flat, shoe-facing surface,
a traction element depending from the hub ground-facing surface, and
a cleat connector extending distally from the hub-shoe-facing surface, wherein the cleat connector is adapted to mate with the receptacle.
10. The athletic shoe of claim 9 , wherein the cleat connector mates with the receptacle in a predetermined orientation to align the traction element in a predetermined position with respect to the sole.
11. The athletic shoe of claim 9 , wherein the cleat assembly comprises a unitary structure formed via a molding process.
12. The athletic shoe of claim 9 , wherein:
the hub comprises one or more flex points, each flex point configured to enable bending of the hub at the flex point; and
at least one flex point comprises a radially extending notch formed into the hub.
13. The athletic shoe of claim 9 , wherein the hub comprises material having a first hardness value, the traction element comprises material having a second hardness value, the first hardness value being different from the second hardness value.
14. The athletic shoe of claim 9 , wherein:
the receptacle comprises an elongated, asymmetrical cavity formed within the sole; and
the cavity is configured to receive the cleat assembly in a predetermined orientation such that the traction elements align with the sole in a predetermined position.
15. The athletic shoe of claim 9 , wherein the elongated hub is configured to flex along its longitudinal axis to accommodate the arcuate portion of the receptacle.
16. The athletic shoe of claim 9 , wherein a plurality of traction elements depend from the hub in longitudinally spaced relation.
17. A method of providing traction to the sole of an athletic shoe, the method comprising:
(a) forming a sole having:
a forward portion, an intermediate portion, and a rear portion,
a ground-facing surface and a shoe-facing surface that cooperate to define a sole peripheral edge, and
a sole longitudinal dimension and sole latitudinal dimension;
(b) forming an elongated receptacle within the sole, wherein the receptacle couples to a traction cleat, wherein at least a portion of the receptacle extends along the sole longitudinal dimension; and
(c) coupling a cleat assembly to the receptacle, the cleat assembly including:
a cleat connector, and
an elongated hub having a substantially semicircular cross section defining generally rounded, ground-facing surface and a generally flat, shoe-facing surface, and a plurality of traction elements depending from and spaced longitudinally along the hub,
wherein shoe-facing surface of the hub is configured to cover the receptacle to prevent debris from entering the receptacle when the cleat assembly is coupled to the receptacle.
18. The method of claim 17 , wherein
the plurality of traction elements depend from the ground-facing surface of the hub.
19. The method of claim 17 , wherein:
the hub comprises an elongated hub defining a longitudinal hub axis;
the hub is configured to flex laterally along its longitudinal hub axis; and
the method further comprises (d) flexing the hub to accommodate the arcuate portion of the receptacle.
20. The traction cleat system of claim 1 , wherein at least a portion of the receptacle extends along the sole longitudinal dimension.
21. The traction cleat system of claim 1 , wherein the cleat connector mates with the receptacle in a predetermined orientation to align the traction elements in a predetermined position with respect to the sole.
