Changes in under-shoe traction and fluid drainage for progressively worn shoe tread

Slip and fall accidents are a common cause of injuries in the workplace. Slip-resistant footwear offers the potential to reduce the risk of these accidents. However, the efficacy of these shoes is reduced as shoes become worn. This data set provides the key independent and dependent variables from a study to evaluate the changes in traction performance of slip-resistant shoes as they become worn. The traction performance of five shoes were tracked as these shoes were exposed to mechanical wear. The coefficient of friction and under-shoe fluid pressures were measured in their baseline condition and after each worn iterations. During each wear iterations, shoes were mechanically worn at three different angles to simulate the shoe angle progression during the weight-acceptance phase of gait. Coefficient of friction was quantified as the ratio of friction to normal forces. The peak fluid pressure and the fluid force (spatial integral of fluid pressure) were calculated. The worn region size ...
