An article of footwear is disclosed that includes an upper and a sole structure secured to the upper. The sole structure incorporates a support element that includes a fluid-filled chamber, a first insert, and a second insert. The chamber defines a first surface, an opposite second surface, and a sidewall extending between the first surface and the second surface. The first insert is secured to the first surface and at least partially recessed into the polymer material of the chamber, and the second insert is secured to the second surface. In addition, the chamber may be pressurized to deform the first insert or the second insert.

That which is claimed is: 1. An article of footwear having an upper and a sole structure secured to the upper, the sole structure incorporating a support element comprising: a sealed fluid-filled chamber formed of a polymer material and defining a first surface having an interior side in contact with the fluid within the chamber and an exterior side not contacting the fluid within the chamber, an opposite second surface having an interior side in contact with the fluid within the chamber and an exterior side not contacting the fluid within the chamber, and a sidewall extending between the first surface and the second surface; a first insert secured to the exterior side of the first surface and at least partially recessed into the polymer material of the chamber; and a second insert secured to the exterior side of the second surface, wherein the sole structure defines a void positioned in a heel region of the article of footwear, and the support element and three additional support elements are located within the void and extend between upper and lower surfaces of the void. 2. The article of footwear recited in claim 1, wherein conduits place the support element and the three additional support elements in fluid communication. 3. The article of footwear recited in claim 1, wherein the second insert is at least partially recessed into the polymer material of the chamber. 4. The article of footwear recited in claim 1, wherein the chamber is devoid of internal connections that join the first surface and the second surface. 5. The article of footwear recited in claim 1, wherein the chamber has a cylindrical configuration. 6. The article of footwear recited in claim 1, wherein the chamber is pressurized and sealed. 7. The article of footwear recited in claim 1, wherein the chamber is pressurized to deform at least one of the first insert and the second insert. 8. The article of footwear recited in claim 1, wherein the chamber is pressurized to place an outward force upon the first surface and deform the first insert to decrease a curvature of the first insert. 9. The article of footwear recited in claim 1, wherein the first insert has a configuration of a plate. 10. An article of footwear having an upper and a sole structure secured to the upper, the sole structure comprising: a midsole that defines a void positioned in a heel region of the footwear and extending through a medial side and a lateral side of the footwear, the void having an upper surface and an opposite lower surface; and at least four support elements located within the void and extending between the upper surface and the lower surface, at least one of the support elements including: (a) a fluid-filled chamber formed of a polymer material and having a first surface having an interior side in contact with the fluid within the chamber and an exterior side not in contact with the fluid within the chamber, an opposite second surface having an interior side in contact with the fluid within the chamber and an exterior side not in contact with the fluid within the chamber, and a sidewall extending between the first surface and the second surface, the chamber being devoid of internal connections that join the first surface and the second surface, and (a) a first insert and a second insert, the first insert being secured to the exterior side of the first surface and at least partially recessed into the polymer material, and the second insert being secured to the exterior side of the second surface, wherein the first insert has an unflexed configuration and a flexed configuration, the first insert having a first degree of curvature in the unflexed configuration, and the first insert having a second degree of curvature in the flexed configuration, the first degree of curvature being greater than the second degree of curvature, and the chamber being pressurized such that an outward force upon the first surface deforms the first insert from the unflexed configuration to the flexed configuration. 11. The article of footwear recited in claim 10, wherein conduits place the four support elements in fluid communication. 12. The article of footwear recited in claim 10, wherein the second insert is at least partially recessed into the polymer material of the chamber. 13. The article of footwear recited in claim 10, wherein the chamber has a cylindrical configuration. 14. The article of footwear recited in claim 10, wherein the first insert has a configuration of a plate. 15. The article of footwear recited in claim 10, wherein a pair of plates form the upper surface and the lower surface of the void, the first insert and the second insert being secured to the plates.
