• Description:
  Shoe tread is intended to mitigate under-shoe fluid pressures. As tread becomes worn, its performance can be compromised. Previous modeling studies have suggested that under-shoe lubrication behavior is sensitive to the size of the worn region. The goal of this study was to determine whether the size of the worn region on shoes can predict under-shoe fluid pressures. Forty-one participants were exposed to a liquid contaminant (90% glycerol) in their own used shoes. Thirty fluid pressure sensors, embedded in the floor, recorded under-shoe fluid pressures to quantify the peak pressure. The size of the worn region was the product of the length and width of the worn heel region. Linear regression assessed the impact of worn tread size on peak pressure. The worn region predicted the peak pressure for both slip-resistant and non-slip-resistant shoes (p=0.003). Thus, using the dimensions of the worn region appears to be a reasonable method for determining when worn shoes should be replaced. [Description provided by NIOSH]
