Method for producing a sole of a shoe, in particular of a sports shoe

A sole structure, comprising:

• a plurality of cavities disposed along a longitudinal direction of the sole structure,
• wherein each cavity of the plurality of cavities includes a first rounded end, a second rounded end opposite and spaced apart from the first rounded end in the longitudinal direction, and side edges connecting opposite ends of the first rounded end and the second rounded end,
• wherein each of the plurality of cavities includes a single major axis that extends between the first rounded end and the second rounded end,
• wherein a front side edge and a rear side edge of each cavity of the plurality of cavities taper inward from the first rounded end toward the second rounded end, and
• wherein a first major axis of a first cavity of the plurality of cavities is angularly offset from a second major axis of a second cavity of the plurality of cavities.

An article of footwear, comprising:

• a sole structure including a midsole, the midsole including a plurality of cavities, each of the plurality of cavities defined by a first rounded end, a second rounded end opposite and spaced apart from the first rounded end in a longitudinal direction, a first side edge, and a second side edge opposite the first side edge,
• wherein the first side edge and the second side edge connect opposite ends of the first rounded end with the second rounded end,
• wherein each cavity of the plurality of cavities includes a single major axis between the first rounded end and the second rounded end,
• wherein the first side edge and the second side edge taper inward from the first rounded end toward the second rounded end,
• wherein the plurality of cavities includes a first row of cavities and a second row of cavities different than the first row of cavities, the first row of cavities and the second row of cavities each extending in a transverse direction over an entire width of the midsole, and
• wherein the plurality of cavities is configured to collapse or deform the midsole when a force is applied downward.
