Footwear

A footwear sole assembly comprising:

• a sole body defining voids of different depths, the voids arranged to provide relatively greater cushioning and bendability within at least one of a metatarsus portion and a calcaneus portion of the sole body;
• wherein a heel top surface of the footwear sole assembly is elevated between about 4 mm and about 12 mm above a forefoot top surface of the footwear sole assembly;
• wherein voids defined in the metatarsus and calcaneus portions of the sole body have at least one of a larger cross-sectional area and a deeper depth than any remaining voids defined by the sole body.

A footwear sole assembly comprising:

• a sole body defining voids of different depths, the voids arranged to provide relatively greater cushioning and bendability within at least one of a metatarsus portion and a calcaneus portion of the sole body;
• wherein a heel top surface of the footwear sole assembly is elevated between about 4 mm and about 12 mm above a forefoot top surface of the footwear sole assembly;
• wherein the sole body defines a two-dimensional array of voids each having a substantially square cross-sectional shaped in a top surface of the sole body, the array having first and second perpendicular axes, both arranged to form an angle of about 45° with respect to a transverse axis of the sole body, voids defined in the metatarsus portion having a relatively deeper depth than voids defined by other portions of the sole body.

A midsole for an article of footwear, the midsole comprising a midsole body defining voids of different depths, the voids arranged to provide relatively greater cushioning and bendability within at least one of a metatarsus portion and a calcaneus portion of the midsole body, wherein a top surface of the midsole in the calcaneus portion is elevated between about 4 mm and about 12 mm above a top surface of the midsole in the metatarsus portion, wherein voids defined in the metatarsus portion of the midsole body have at least one of a larger cross-sectional area and a deeper depth than voids defined in a heel portion of the midsole body.
