Abstract: A sole structure includes a main body formed of a first material and at least one insert formed of a second material. The main body defines first portion of a ground-engaging surface including a first channel defined by a first segment extending along a first axis and a second segment extending along a second axis transverse to the first axis. The one or more inserts are received in sockets formed in the main body. The at least one insert defines a second portion of the ground-engaging surface and has a second channel including a third segment extending along a third axis parallel to the first axis and a fourth segment extending along a fourth axis transverse to the third axis and substantially parallel to the second axis. One of the first channel and the second channel defines an interface between the main body and the insert.
