Article of footwear having an elevated plate sole structure

摘要

An impact-attenuating support system for an article of footwear having an upper and a sole structure is provided. The sole structure includes a midsole formed from a foamed polymer material and is positioned adjacent to the upper and an outsole at a bottom portion of the article of footwear opposite the upper is configured to engage the ground during use. The impact-attenuating support system comprises a plurality of impact-attenuating members located in a heel portion of the sole structure extending between the midsole and the outsole, the plurality of impact-attenuating members each having a general columnar configuration with a central axis extending between the midsole and outsole in an upright direction toward the upper. Each of the plurality of impact-attenuating members comprises a support leg formed from a substantially non-foamed polymer material and being disposed substantially parallel with the central axis, the support leg having a first stiffness; and a core disposed about the support leg and formed from a polymer material having a second stiffness different from the first stiffness; and an upper plate formed from a non-foamed polymer material having an upper surface oriented toward the upper and an opposite lower surface oriented away from the upper, the upper plate being attached to an upper region of each of the support legs.
