Abstract
A shoe cleaning mat employs a plurality of spaced projections on a base layer, all projecting to substantially the same height to provide a stable support. Some of the projections are each provided with an array of radially extending ribs which are progressively deeper in the radially outward direction to provide corresponding increasing elasticity. Two different sizes of such projections are employed and a third type of projection, smaller than the other two, is provided with vertically extending side ribs which are progressively deeper in upward direction.
