Braided upper with multiple materials
An article of footwear is formed from multiple braided components. The braided components may be braided strands formed from different tensile elements. The tensile elements may have different cross-sections. The tensile elements may be from different materials. Different braided strands may then be over-braided over a last to form a braided upper for the article of footwear.

wherein the first braided strand is different than the second braided strand; and
wherein the first braided strand oriented along a first direction is braided with the second braided strand oriented along a second direction at a bias relative to the first direction to form at least a region of the braided upper and wherein one of the first braided strand and the second braided strand is an axial component of the braided upper.
