Abstract
An article of footwear includes an upper and a sole structure having an outer periphery and one or more pontoons flexibly and resiliently joined to the sole structure. The pontoons are configured to spread laterally when the footwear is loaded to thereby increase the surface area of the sole structure and elastically retract back to an original position when the footwear is unloaded. The increased surface area of the sole reduces sinking of the footwear in soft, loose or saturated ground. Optionally, the sole structure includes paddle blades.
