ABSTRACT:
An improved combination walk-off and fatigue mat constitutes an improvement over the mat of U.S. Pat. No. 3,703,059 in the provision of three additional structural features, namely tertiary ribs which prevent the upper ribs from spreading apart and catching spiked heels, pile carpet strips to better clean the bottoms of wet shoes, and separately molded clip elements to mechanically hold the fabric pile strips in place between adjacent top ribs.
