Abstract
An article of footwear includes an upper, a first sole member, and a second sole member. The first sole member is connected to the upper. Together, the first sole member and the upper define a cavity. The first sole member includes an outer surface and a textured inner surface, the textured inner surface defining a pattern of shapes. The second sole member is positioned in the cavity. The second sole member includes a textured lower surface directly engaging the textured inner surface of the first sole member. The textured lower surface of the second sole member is complementary to the textured inner surface of the first sole member.

A method of making a sole member for an article of footwear comprising:
- providing a lower member including a toe portion and a heel portion, the heel portion having a greater hardness than the toe portion, the lower member including a textured upper surface defining a first pattern of shapes;
- providing an elevated member including textured lower surface defining a second pattern of shapes that is complementary to the first pattern of shapes, the elevated member having a lesser hardness than the heel portion;
- and
- engaging the textured lower surface of the elevated member with the textured upper surface of the lower member such that the textured upper surface of the lower member is interlocked with the textured lower surface of the elevated member.

A sole member for an article of footwear comprising:
- a lower member including a contoured upper surface defining a first pattern of shapes, each shape in the first pattern of shapes including a first plurality of peaks and a first plurality of indentations with a first plurality of facets extending between the first plurality of peaks and the first plurality of indentations;
- and
- an elevated member including contoured lower surface defining a second pattern of shapes that is complementary to the first pattern of shapes, the contoured lower surface of the elevated member engaging the contoured upper surface of the lower member such that the contoured upper surface of the lower member is interlocked with the contoured lower surface of the elevated member, the elevated member having a lesser hardness than the lower member.
