The sole structure includes an outsole having a ground-engaging surface and an upper surface formed on an opposite side of the outsole than the ground-engaging surface. A first cushion is disposed proximate to a medial side of the sole structure and includes a first fluid-filled chamber attached to the upper surface of the outsole and a second fluid-filled chamber attached to the first fluid-filled chamber and disposed between the first fluid-filled chamber and the upper. A second cushion is disposed proximate to a lateral side of the sole structure and includes a third fluid-filled chamber attached to the upper surface of the outsole and a fourth fluid-filled chamber attached to the third fluid-filled chamber and disposed between the third fluid-filled chamber and the upper. The second cushion is fluidly isolated from the first cushion.
