众所周知，穿鞋会增加滑倒的风险，但很少有研究系统地研究这种关系。本研究探讨了渐进式鞋磨损对有效摩擦系数（ACOF）和鞋流体动力学的影响。五种不同的防滑鞋逐渐磨损使用加速，研磨，磨损协议。当鞋子滑过被稀释的甘油溶液污染的表面时，测量ACOF和流体力（由流体支撑的载荷）。随着鞋子的磨损，ACOF最初增加，随后稳步下降。在磨损之前观察到低流体力，然后随着磨损区域变大而增加流体力。结果表明，牵引性能下降，特别是当脚跟区域没有胎面超过800毫米（2）的大小。这项研究支持的概念，发展鞋更换准则的基础上磨损区域的大小，以减少职业失误。
Shoe wear is known to increase slipping risk, but few studies have systematically studied this relationship. This study investigated the impact of progressive shoe wear on the available coefficient of friction (ACOF) and under shoe fluid dynamics. Five different slip-resistant shoes were progressively worn using an accelerated, abrasive, wear protocol. The ACOF and fluid forces (the load supported by the fluid) were measured as shoes were slipped across a surface contaminated with a diluted glycerol solution. As the shoes became worn, an initial increase in ACOF was followed by a steady decrease. Low fluid forces were observed prior to wear followed by increased fluid forces as the worn region became larger. Results suggest that traction performance decreases particularly when the heel region without tread exceeds a size of 800 mm(2). This study supports the concept of developing shoe replacement guidelines based upon the size of the worn region to reduce occupational slips.
