A bladder for an article of footwear includes a support chamber and an expansion chamber. The support chamber has a top wall, a bottom wall, and a peripheral wall extending between the top wall and the bottom wall and defining a peripheral profile of the support chamber. The expansion chamber extends from the peripheral wall at a first end of the bladder. In some examples, the peripheral wall defines a first end of the support chamber having one or more lobes extending from the top wall to the bottom wall. The one or more lobes may include a first lobe disposed adjacent to a first side of the support chamber and a second lobe disposed adjacent to a second side of the support chamber. The expansion chamber may be disposed between the first lobe and the second lobe at the first end of the support chamber.
