A hollow sole is formed within the sole of a shoe wherein a top component having a flat portion and an outer wall is adhered to a bottom component wherein the depth of the outer wall defines an enclosed space between the top and bottom components. The outer wall of the top component and the walls of the bottom component that rise to and fall from the weld lines are made with flexible ridges which provides a bellowing effect when the pressure of the foot is pushed down on the sole. In one embodiment, a fluidly connected inside compartment and outside compartment are created by welded lines adhering the bottom component to the top component. In an alternate embodiment, the hollow sole may contain foam for extra support. Fluid pockets and other flow structures are bored into the foam to allow for the dynamic fluid flow.

The shoe sole according to claim 17, wherein said sidewall forms an exterior wall of said sole. 21. The shoe sole according to claim 10, wherein said foam core comprises a first piece of foam having a first density and a second piece of foam having a second density. 22. The shoe sole of claim 10, wherein said foam core and said container jointly define multiple compartments fluidly connected to one another via at least one fluid channel. 23. The shoe sole of claim 22 wherein said at least one channel is jointly defined by said container and said foam core. 24. The shoe sole of claim 23 wherein said compartments have a first depth measured from a surface of said foam core and said at least one channel has a second depth measured from said surface of said foam core, wherein said first depth is greater than said second depth. 25. The article of footwear of claim 10, wherein said foam core comprises a single piece of foam. 26. The article of footwear of claim 10, wherein said stepped ridge includes an first section, substantially perpendicular to said first wall, a second section substantially perpendicular to said first wall, and a ridge separating said first second and said second section. 27. The article of footwear of claim 26, wherein said ridge is a flat surface. 28. The article of footwear of claim 26, wherein said ridge includes a peak and a trough. 29. The shoe sole of claim 10, wherein said foam core includes at least one compartment. 30. The shoe sole of claim 10, wherein said foam core includes a plurality of compartments connected by a fluid channel. 31. The shoe sole of claim 10, wherein said foam core includes a top surface, a bottom surface and a side surface wherein a portion of said side surface includes a plurality of stepped ridges increasingly protruding from said top surface to said bottom surface. 32. The shoe sole of claim 10, wherein said shoe sole further comprises an outsole defining said ground engaging surface, wherein said outsole is coupled to said bottom wall of said container. 33.
