Dependent claims

A sole structure for an article of footwear, the sole structure comprising:

a midsole including a first portion extending from a forefoot region of the sole structure to a heel region of the sole structure and a second portion extending from the forefoot region of the sole structure to the heel region of the sole structure, the first portion of the midsole and the second portion of the midsole being spaced apart from one another in the heel region;
a bladder including a first fluid-filled segment extending along a medial side of the sole structure from the forefoot region to the heel region and a second fluid-filled segment extending along a lateral side of the sole structure from the forefoot region to the heel region;
and
an outsole including a first portion extending around a periphery of the bladder and a second portion spaced apart from the first portion, the first portion of the midsole being exposed in a region between the first portion of the outsole and the second portion of the outsole and between the first fluid-filled segment and the second fluid-filled segment of the bladder in the forefoot region, the second portion of the outsole disposed in the forefoot region of the sole structure and in contact with the first portion of the midsole between the first fluid-filled segment and the second fluid-filled segment of the bladder.
