The present work discusses the effect of the treads width and depth of the shoe sole on the friction coefficient between the shoe and ceramic floor interface. The friction coefficient was measured by using a test rig designed and manufactured for this purpose. Rubber test specimens were loaded against dry, water and water/detergent mixture, oil and oil/water dilution lubricated flooring tiles. It was found that, at dry sliding, friction coefficient slightly increased with increasing treads height. Perpendicular treads displayed the highest friction coefficient due to their increased deformation, while parallel treads showed the lowest values. In the presence of water on the sliding surface significant decrease in friction coefficient was observed compared to the dry sliding
