A sole construction (110, 310, 410, 510) for supporting at least a portion of a foot and for providing energy storage and return is provided. The sole construction (110, 310, 410, 510) includes a generally horizontal layer (126, 156, 326, 356, 426, 456, 526, 556) of stretchable material, at least one chamber (130, 132, 134, 330, 332, 334, 354, 354′, 430, 432, 434, 454, 454′, 530, 532, 534, 554, 554′) positioned adjacent a first side of the layer (126, 156, 326, 356, 426, 456, 526, 556), and at least one actuator (122, 158, 320, 322, 324, 358, 420, 422, 424, 458, 520, 522, 524, 558) positioned adjacent a second side of the layer (126, 156, 326, 356, 426, 456, 526, 556) vertically aligned with a corresponding chamber (130, 132, 134, 330, 332, 334, 354, 354′, 430, 432, 434, 454, 454′, 530, 532, 534, 554, 554′). The sole (110, 310, 410, 510) when compressed causes the actuator (122, 158, 320, 322, 324, 358, 420, 422, 424, 458, 520, 522, 524, 558) to push against the layer (126, 156, 326, 356, 426, 456, 526, 556) and move the layer (126, 156, 326, 356, 426, 456, 526, 556) at least partially into the corresponding chamber (130, 132, 134, 330, 332, 334, 354, 354′, 430, 432, 434, 454, 454′, 530, 532, 534, 554, 554′).
