A sole structure for an article of footwear includes an upper element, a lower element positioned below the upper element and a flexure element. The flexure element may be joined to one of the upper element and the lower element. The flexure element may be configured for slidingly contacting the other of the upper element and the lower element when a vertical compressive load is applied to the upper element. A second flexure element may be provided that extends from the upper element toward the lower element (or vice versa). An article of footwear having the sole structure attached to an upper is also provided.

Sole structure for an article of footwear

A method of forming a sole assembly of an article of footwear including an interior space and an exterior surface includes providing a first portion of the sole assembly. The first portion includes a first surface that at least partially defines the interior space and a first chamber surface that opposes the first surface. The first portion is made from a first material. The method also includes providing a second portion of the sole assembly that includes a second surface that at least partially defines the exterior surface of the article of footwear and a second chamber surface that opposes the second surface. The second portion is made from a second material that is different from the first material. The method additionally includes operably securing the first and second portions such that the first chamber surface and the second chamber surface cooperate to at least partially define a chamber.

Sole assembly with plural portions that cooperatively define chamber

A method of forming a sole assembly of an article of footwear that includes an interior space that receives a foot of a wearer is disclosed. The article of footwear also includes an exterior surface. The method includes providing a first portion of the sole assembly. The first portion includes a first surface that at least partially defines the interior space. The first portion also includes a first chamber surface that opposes the first surface. Moreover, the method includes providing a second portion of the sole assembly. The second portion includes a second surface that at least partially defines the exterior surface of the article of footwear. The second portion also includes a second chamber surface that opposes the second surface. The method further includes operably securing the first portion to the second portion such that the first chamber surface and the second chamber surface cooperate to at least partially define a substantially sealed chamber within the sole assembly.
