The invention described herein is a self-cleaning footwear system comprising a sole, where a plurality of check valves are located within said sole. The plurality of check valves are preferably configured between an upper sole and a lower sole to allow debris to flow downwards but not upwards. The plurality of check valves preferably further comprise flap assemblies, where a length of flexible material preferably further comprises a semi-circular flap on one end. The flexible material is preferably a rubber-type material. The sole could be attached to normal footwear, as shown in a sandal. Alternately, the sole could be attached to any type of footwear.
