Sole and footwear

A sole constituting a part of footwear, the sole comprising:

• an outer sole having a front side and a rear side;
• a midsole disposed on the outer sole, the midsole including a lower midsole and an upper midsole, the lower midsole being lower in rigidity than the upper midsole;
• and
• a plate disposed at the midsole, the plate being higher in rigidity than the midsole, the plate located between the lower midsole and the upper midsole,
• the plate and the lower midsole located within a cavity in the upper midsole,
• the plate including a toe section disposed at a position to overlap a toe portion of a wearer in a thickness direction of the sole, and a midfoot section having a shape extending rearward from the toe section in a longitudinal direction of the footwear, the midfoot section being disposed at a position overlapping, in the thickness direction, a midfoot portion located at a center of a foot of the wearer in the longitudinal direction,
• the toe section including a fore edge part disposed at a position to overlap, in the thickness direction, a first distal phalanx and a second distal phalanx of the wearer and having a forward convex-curved shape in the longitudinal direction, a recessed edge part having a shape extending rearward in the longitudinal direction while extending from a lateral end of the fore edge part in a width direction of the footwear toward a lateral side in the width direction and convex-curved toward a medial side in the width direction, and a lateral edge part having a shape extending rearward in the longitudinal direction from a lateral end of the recessed edge part in the width direction and convex-curved toward the lateral side in the width direction, and
• the midfoot section including a medial connecting edge part extending rearward from the toe section in the longitudinal direction along the medial side, a lateral connecting edge part extending rearward from the toe section in the longitudinal direction along the lateral side, and a rear edge part having a rear edge extending from the medial connecting edge part to the lateral connecting edge part so as to cross a center portion of a first metatarsal, a center portion of a second metatarsal, a center portion of a third metatarsal, a center portion of a fourth metatarsal, and a center portion of a fifth metatarsal of the wearer in the thickness direction.
