Sole structure for article of footwear
A plate for a sole structure of an article of footwear includes a platform extending from a first platform end to a second platform end, the platform being substantially planar from the first platform end to the second platform end, a first arcuate segment extending in a first direction from the first platform end to a first distal end, and a second arcuate segment extending in an opposite second direction from the second platform end to a second distal end, the second distal end being coplanar with the first distal end.
1 . A plate for a sole structure of an article of footwear, the plate comprising:
a platform extending from a first platform end to a second platform end spaced from the first platform end, the platform being substantially planar from the first platform end to the second platform end;
a first arcuate segment extending in a first direction from the first platform end to a first distal end; and
a second arcuate segment extending in an opposite second direction from the second platform end to a second distal end, the second distal end being coplanar with the first distal end, the first platform end, and the second platform end.
2 . The plate of claim 1 , wherein the first arcuate segment and the second arcuate segment include different lengths.
3 . The plate of claim 1 , wherein the first arcuate segment includes a first cambered portion defining a first convex surface along a bottom side of the plate having a first radius of curvature.
4 . The plate of claim 3 , wherein the first arcuate segment includes a first transition portion connecting the first cambered portion and the platform.
5 . The plate of claim 4 , wherein the first transition portion curves in an opposite direction than the first cambered portion and is tangent with the platform and the first cambered portion.
6 . The plate of claim 4 , wherein the second arcuate segment includes a second cambered portion defining a second convex surface along the bottom side of the plate having a second radius of curvature.
7 . The plate of claim 6 , wherein the second radius of curvature is greater than the first radius of curvature.
8 . The plate of claim 7 , wherein the second arcuate segment includes a second transition portion connecting the second cambered portion and the platform.
9 . The plate of claim 8 , wherein the second transition portion curves in an opposite direction than the second cambered portion and is tangent with the platform and the second cambered portion.
10 . A sole structure for an article of footwear, the sole structure comprising:
a cushioning element; and
a plate embedded within the cushioning element and including a planar platform extending from a first platform end to a second platform end spaced from the first platform end, a first arcuate segment extending in a first direction from the first platform end to a first distal end, and a second arcuate segment extending in an opposite second direction from the second platform end to a second distal end, the second distal end being coplanar with the first distal end and the planar platform.
11 . The sole structure of claim 10 , further comprising a cushioning arrangement including one or more compressible elements disposed between the plate and the cushioning element.
12 . The sole structure of claim 11 , wherein each of the compressible elements includes a bladder having an upper barrier layer and a lower barrier layer enclosing a chamber.
13 . The sole structure of claim 12 , wherein each bladder includes a tensile member including a plurality of tensile strands each extending between the upper barrier layer and the lower barrier layer.
14 . The sole structure of claim 13 , wherein the tensile strands cooperate with the upper barrier layer and the lower barrier layer to provide each bladder with a substantially planar top side and a substantially planar bottom side.
15 . The sole structure of claim 11 , wherein the compressible elements include resilient polymeric materials.
16 . The sole structure of claim 15 , wherein the compressible elements include foam.
17 . The sole structure of claim 11 , wherein the cushioning arrangement includes a first cushioning structure disposed adjacent to a medial side of the sole structure and a second cushioning structure disposed adjacent to a lateral side of the sole structure.
18 . The sole structure of claim 17 , wherein at least one of the first cushioning structure and the second cushioning structure includes a first bladder adjacent to the plate and a second bladder disposed between the first bladder and the cushioning element.
19 . The sole structure of claim 18 , wherein the first bladder includes at least one of a different width and a different height than the second bladder.
