Patent ID: 11324280

Abstract:
A footwear apparatus includes a primary outsole having a primary cavity, a secondary outsole connected to the primary outsole and having a secondary cavity, a midsole movably disposed over the primary outsole and secondary outsole including a primary protrusion extending at least partially within the primary cavity, and a tertiary outsole disposed about the primary protrusion. The footwear apparatus defines a z-axis through the secondary cavity and substantially normal to a ground surface, a y-axis extending substantially from the secondary cavity to the primary cavity, and an x-axis substantially normal to a plane created by the z-axis and the y-axis. The midsole is configured to rotate substantially about the x-axis, rotate substantially about the y-axis, to resist rotation substantially about the z-axis. The footwear apparatus is adaptive to a ground surface orientation on which the wearer walks and to rotational movements of the wearers body.
