A sole structure for an article of footwear may include a chamber for receiving a pressurized fluid, the chamber having a first chamber barrier layer and a second chamber barrier layer bonded to the first chamber barrier layer about peripheral portions of the first chamber barrier layer and the second chamber barrier layer to define an interior void between the first chamber barrier layer and the second chamber barrier layer. The sole structure may also include a tensile member bonded to, and extending between, the first chamber barrier layer and the second chamber barrier layer. The sole structure may include a bond inhibiting material located between the tensile member and the first chamber barrier layer, the tensile member and the first chamber barrier layer being unbonded in an unbonded area in which the bond inhibiting material is disposed. The chamber may include an outwardly extending bulge in the unbonded area.

A sole structure for an article of footwear includes a chamber having a first barrier element, a second barrier element, and a tensile member. The tensile member is disposed within an interior void defined by the first barrier element and the second barrier element. The sole structure further includes a phase change material disposed within the interior void and operable between a first state in a first temperature range and a second state in a second temperature range. The first temperature range is from 30° C. to 35° C. and the second temperature range is from 35° C. to 42° C. The sole structure further includes an insulating member disposed between the chamber and a ground contacting surface.

A sole structure with an integrated cleat member includes a plate member with a protruding portion that forms a first portion of the cleat member. A second portion of the cleat member is attached to the first portion and may be made of a less rigid material than the first portion. A supporting structure can be disposed inside the protruding portion. A method of forming the sole structure can include reshaping a portion of a plate member to form a protruding portion, molding a cleat tip portion onto the protruding portion and molding a supporting structure into a concave inner portion of the protruding portion.
