Title: LOCKING MIDSOLE AND INSOLE ASSEMBLY
Abstract:
A footwear item (10) includes an insole (300), an outsole (100, 400), and a midsole (100). The insole (300) includes an insole top surface (302), an insole bottom surface (304), and an insole sidewall (306). The outsole (100, 400) includes an outsole (100, 400) top surface and an outsole (100, 400) bottom surface. The midsole (100) is positioned between the insole (300) and the outsole (100, 400). The midsole (100) is configured to nest onto the top surface of the outsole (100, 400). In at least the heel region, the midsole (100) includes a strobel (200) upper (202) surface and a strobel (200) sidewall configured to nestingly receive a heel region of the insole (300). In addition, an interface (106) between the strobel (200) upper (202) surface and the strobel (200) sidewall includes a fillet region (106) configured to support and reduce lateral-medial movement of the insole (300) relative to the midsole (100).
