Abstract
An article of footwear includes an upper and a sole structure. The sole structure has a longitudinal extension in a longitudinal direction and a vertical extension in a vertical direction. The sole structure defines a plurality of recesses arranged at least in a rearfoot region thereof and extend at least partially into the sole structure in a transverse direction and along a straight line that extends in the longitudinal direction. Without external forces on the sole structure, each recess of the plurality of recesses is larger in a first direction than in a second direction. The sole structure is configured to provide predetermined dampening and spring deflection characteristics such that, when an external force is applied to the sole structure, the plurality of recesses collapse in a predetermined manner and, when the external force is removed, the plurality of recesses expand back to their original shape.
