The variability in friction and slip propensity across slip resistant (SR) shoes is poorly understood. This study aimed to quantify the impact of shoe design features on the available coefficient of friction (ACOF) across shoes labeled as SR. Differences in ACOF and the slipping rate across SR shoes were also quantified. Twelve shoes were tested across five types of flooring and three contaminant conditions using a whole shoe mechanical slip tester. Geometric and hardness parameters were measured to determine the effect of heel outsole design on ACOF. The rate of slipping was evaluated for three of the shoes on vinyl tile with canola oil using human subjects. Differences in ACOF were significant across shoe outsole designs (p < .001). ACOF was correlated with geometrical and hardness parameters. Rate of slipping was lower for the highest ACOF shoe (p < .001). This information can be used to guide SR shoe selection and design.
防滑（SR）鞋之间的摩擦力和滑动倾向差异很大，但目前对此了解甚少。本研究旨在定量分析鞋类设计特征对标注为 SR 的鞋子的有效摩擦系数（ACOF）的影响。同时，还对 SR 鞋之间的 ACOF 和滑动率差异进行了量化。使用全鞋机械滑动测试仪，在五种地板类型和三种污染条件下对 12 种鞋子进行了测试。测量了几何和硬度参数，以确定鞋跟外底设计对 ACOF 的影响。在使用菜籽油的乙烯基地板上，对其中三双鞋的滑动率进行了人体受试者评估。鞋底设计不同的鞋子之间的 ACOF 差异具有统计学意义（p <.001）。ACOF 与几何和硬度参数相关。ACOF 最高的鞋子的滑动率更低（p <.001）。这些信息可用于指导 SR 鞋的选择和设计。
