1. A sole structure for an article of footwear, comprising:
a first bladder;
a second bladder;
a valve body defining: (a) a bore, (b) a first fluid passage extending to the bore, (c) a second fluid passage extending between the bore and the first bladder, and (d) a third fluid passage extending between the bore and the second bladder; and
a first valve provided in the bore, wherein the first valve includes (a) a first orifice, (b) a second orifice, and (c) a passage connecting the first orifice and the second orifice,
wherein the first valve is movably mounted with respect to the bore and is movable between a first position and a second position, wherein:
in the first position, the first orifice is in fluid communication with the first fluid passage and the second orifice is in fluid communication with the second fluid passage to allow fluid flow between the first fluid passage and the first bladder to inflate the first bladder to a first pressure, and
in the second position, the first orifice is in fluid communication with the third fluid passage and the second orifice is in fluid communication with the first fluid passage to allow fluid flow between the first fluid passage and the second bladder to inflate the second bladder to a second pressure, wherein the second pressure is different from the first pressure.
