The measurement of the slip resistance of footwear is inherently difficult due to the complexity of the human gait, which leads to changing values of the biomechanical parameters during the walking step. Only some steps result in a slipping heel, which compounds the difficulty in identifying the values of the parameters that need to be simulated. A number of studies have attempted to measure the parameters of walking and/or a slip, in order that realistic values can be incorporated into tests attempting to replicate the slip process.
