Interlocking Fluid-Filled Chambers For An Article Of Footwear

An article of footwear having an upper and a sole structure secured to the upper, the sole structure comprising:

• a first chamber that encloses a fluid and is positioned adjacent the upper, the first chamber including a periphery that defines a plurality of first projections and a plurality of first depressions located between the first projections;
• and
• a second chamber that encloses a fluid and is positioned adjacent the first chamber, the second chamber including a periphery that defines a plurality of second projections and a plurality of second depressions located between the second projections,
• at least a portion of the first projections being located within the second depressions, and at least a portion of the second projections being located within the first depressions.

An article of footwear having an upper and a sole structure secured to the upper, the sole structure comprising:

• a first chamber that encloses a fluid, the first chamber having a first surface with a first contoured configuration;
• and
• a second chamber that encloses a fluid, the second chamber having a second surface with a second contoured configuration,
• the first surface being in contact with the second surface, and the first contoured configuration being shaped to mate with the second contoured configuration.

An article of footwear having an upper and a sole structure secured to the upper, the sole structure comprising:

• a first chamber that encloses a fluid, the first chamber having a first central area and a plurality of first lobes extending outward from the first central area to form a periphery of the first chamber, the first lobes defining a plurality of first spaces located around the periphery of the first chamber;
• and
• a second chamber that encloses a fluid and is positioned adjacent the first chamber, the second chamber having a second central area and a plurality of second lobes extending outward from the second central area to form a periphery of the second chamber, the second lobes defining a plurality of second spaces located around the periphery of the second chamber,
• the first chamber being in contact with the second chamber such that at least a portion of (a) the first lobes extend into the second spaces and (b) the second lobes extend into the first spaces.
