ADAPTIVE MIDSOLE WITH PIN ARRAY

An article of footwear (10A, 10B, I0C, 10) is provided and includes an upper (100), an outsole (210A, 210B, 210C, 210), and a midsole (220A, 220B, 220). The outsole (210A, 210B, 210C, 210) includes a ground-engaging surface and an inner surface (214A, 214B, 214C, 214, 407). The midsole (220A, 220B, 220) has a footbed (1224, 224A, 224B, 224, 22A), a bottom surface (1222, 222A, 222B, 222), and a series (310) of channels (400A, 400B, 400, 410, 420B, 420, 430A, 430B, 430) extending therethrough. The bottom surface (1222, 222A, 222B, 222) opposes the inner surface (214A, 214B, 214C, 214, 407) to define a cavity (240A, 240B, 240C, 240) therebetween. The article of footwear (10A, 10B, I0C, 10) also includes a series (310) of pins (10B, 300A, 300B, 300, 310A, 310B, 310, 320A, 320B, 320, 330A, 330B, 330) each having a post (313) extending through corresponding ones of the series (310) of channels (400A, 400B, 400, 410, 420B, 420, 430A, 430B, 430) between a first end (311, 321, 331B, 331) and a second end (312, 322, 332B, 332). The first end (311, 321, 331B, 331) extends into the cavity (240A, 240B, 240C, 240) outward from the bottom surface (1222, 222A, 222B, 222) of the midsole (220A, 220B, 220) and the second end (312, 322, 332B, 332) extends into the interior void (102, 1252) outward from the footbed (1224, 224A, 224B, 224, 22A) of the midsole (220A, 220B, 220). The article of footwear (10A, 10B, I0C, 10) also includes a resilient member (250A, 250) that engages the first end (311, 321, 331B, 331) of each of the series (310) of pins (10B, 300A, 300B, 300, 310A, 310B, 310, 320A, 320B, 320, 330A, 330B, 330) and biases the series (310) of pins (10B, 300A, 300B, 300, 310A, 310B, 310, 320A, 320B, 320, 330A, 330B, 330) toward the interior void (102, 1252). L'invention concerne un article de chaussures (10A, 10B, I0C, 10) qui comprend une tige (100), une semelle d'usure (210A, 210B, 210C, 210) et une semelle intercalaire (220A, 220B, 220). La semelle d'usure (210A, 210B, 210C, 210) comprend une surface de prise avec le sol et une surface interne (214A, 214B, 214C, 214, 407). La semelle intercalaire (220A, 220B, 220) a une assise plantaire (1224, 224A, 224B, 224, 22A), une surface inférieure (1222, 222A, 222B, 222), et une série (310) de canaux (400A, 400B, 400, 410, 420B, 420, 430A, 430B, 430) s'étendant à travers cette dernière. La surface inférieure (1222, 222A, 222B, 222) s'oppose à la surface interne (214A, 214B, 214C, 214, 407) pour définir une cavité (240A, 240B,
