Abstract
An article of footwear includes a sole with a midsole. A midsole plate includes a lateral fork member and a medial fork member configured to provide flexibility to the phalanges bones during ground engaging actions. The midsole plate includes a plurality of perforations configured for air communication within an upper of an article of footwear. A midsole plate may include a phalanx portion, a metatarsal portion and a midfoot portion corresponding to a foot of a wearer. The phalanx portion, the metatarsal portion, and the midfoot portion each have a different stiffness with respect to each other.
Claims9
An article of footwear, comprising:
- an upper for holding a foot of a wearer;
- and
- a sole including an outsole and a midsole portion attached to the outsole;
- said midsole portion including a resilient material and a midsole plate being coupled to the resilient material, and the midsole plate having a two laterally disposed tines corresponding to a forefoot of a wearer when superimposed thereon, said tines defining a forked geometry;
- wherein the outsole and the midsole portion includes an elongated pathway surrounded by generally perpendicular sidewalls defined by the outsole and the midsole portion, the elongated pathway for air communication within an interior of the upper, the pathway having a distal end defining an air intake for receiving air at the outsole, the pathway having an air outlet opposing the air intake;
- and wherein the midsole plate includes a plurality of apertures configured for the air communication;
- the plurality of apertures of the midsole plate being connected to the elongated pathway via the air outlet.
An article of footwear, comprising:
- an upper for holding a foot of a wearer;
- a sole attached the upper:
- the sole including an outsole and a midsole;
- and
- a midsole plate attached to an upper surface of the midsole;
- the midsole plate having a plurality of perforations so that air is communicated from the outsole through midsole and the midsole plate into the upper;
- wherein an air communication pathway extends through the outsole and the midsole to encompass the plurality of perforations within a superimposed area on the midsole plate formed by the pathway;
- wherein the midsole plate further comprises two distinct forwardly disposed fork members configured to lie underneath a phalanx portion of a foot of a wearer and a predetermined metatarsal portion and a midfoot portion corresponding to a foot of a wearer, the metatarsal portion, and midfoot portion each having a different stiffness with respect to each other.
