SOLE STRUCTURES HAVING MULTIPLE HARDNESSES AND/OR FLEX PROMOTING STRUCTURES

Abstract:

Footwear and sole structures include structures and properties, e.g., to support urban dance and urban dance moves. Such dance styles include various dance moves and movements that require contact between side edges of the wearer's shoes and the dance floor surface (e.g., made from concrete, asphalt, wood, etc.). Such dance styles also require transition of the body's center of mass along the edge(s) of the foot. Footwear and sole structures in accordance with this technology provide structures and properties to support to support such dance styles and moves, including one or more of: selected materials and/or selected material properties in various areas to promote sliding or gliding along various surfaces and/or other desired interactions with various surfaces; selected sizing and/or dimensional features of components in various areas; various flexion promoting structures and/or characteristics; etc.
