Zusammenfassung:	An article of footwear may have an upper and a sole structure secured to the upper. The sole structure has a plurality of support elements, and each of the support elements include a shell and a core. The shell defines an interior void and is formed from a polymer material that extends around substantially all of the void. The core has a shape of the void and is located within the void, with at least a portion of the core being a polymer foam material. The polymer foam material of at least two of the support elements may have different densities.
