Abstract
A sandal useful especially in wet areas and also where there is soft ground such as at the beach. The sandal has opposite side edges that slope in a downward-outward direction, to provide a wider foot print that minimizes sideward twisting on soft ground, to avoid splashing of water onto the wearer, and to avoid disintegration of the side portions of soft rubber sandal material. The bottom surface of the sandal slopes upward at the rear and front to further avoid splashing of water onto the wearer. The lower surface of the sandal has a herringbone pattern, with each ridge interrupted by narrow cross projections that help avoid splipping due to hydroplaning.
