The assessment of slipperiness can effectively be conducted through friction measurements, a method widely employed in various settings. To evaluate the slickness of surfaces, be it floors or footwear, numerous friction-measuring devices, commonly referred to as “slipmeters” or “slip testers,” have been engineered. While all these devices utilize friction as the basis for determining slickness, they vary considerably in their measurement characteristics and methods [1–3]. Different approaches, including static drag-sled measurements, dynamic friction assessments at a constant velocity, and impact testing, have all been utilized to quantify friction levels. The readings obtained from various slipmeters can differ significantly, influenced by the unique features of each device [4–6]. For example, depending on the type of friction being measured, these devices may exhibit substantial variations in key parameters such as the loading contact pressure, the apparent surface areas involved, and the slipping speed at the interface between the footwear and the testing surface [7–10].
