<p>A surface comprises a first set of protrusions (15a...15e, 16a...16e) defining a fluid flow path (12). The surface further comprises a second set of at least one protrusion (13,14), the or each protrusion of the second set being disposed at least partially within the fluid flow path. The second set of protrusions prevents the heel of a shoe, even a narrow heel, from sliding along the fluid flow path, and so provides the surface with a high skid resistance. The skid resistance may be at least 65 as measured in wet conditions by the standard test defined in TRL Road Note No. 27 "Measure of floor slip resistance", and may possibly be at least 75 or even at least 85.</p> |
