An article of footwear may have a sole structure with a chamber, a plate,
and an outsole. The chamber encloses a fluid and has an upper surface and
an opposite lower surface. The plate is positioned adjacent to the upper
surface and has a plurality of projections that extend into indentations
in the chamber. The outsole may be positioned adjacent to the lower
surface and may have a plurality of projections that extend into
indentations in the chamber. In some manufacturing processes for the sole
structure, the plate and outsole may be located within a mold, and the
chamber may then be shaped by surfaces of the plate, outsole, and mold.
