AB  - Measuring the available coefficient of friction (ACOF) of a shoe-floor interface 
      is influenced by the choice of normal force, shoe-floor angle and sliding speed. 
      The purpose of this study was to quantify the quality of slip prediction models 
      based on ACOF values measured across different testing conditions. A dynamic ACOF 
      measurement device that tests entire footwear specimens (Portable Slip Simulator) 
      was used. The ACOF was measured for nine different footwear-contaminant 
      combinations with two levels of normal force, sliding speed and shoe-floor angle. 
      These footwear-contaminant combinations were also used in human gait studies to 
      quantify the required coefficient of friction (RCOF) and slip outcomes. The 
      results showed that test conditions significantly influenced ACOF. The condition 
      that best predicted slip risk during the gait studies was 250 N normal force, 17 degrees  
      shoe-floor angle, 0.5 m/s sliding speed. These findings can inform footwear 
      slip-resistance measurement methods to improve design and prevent slips.
