A large proportion of falls in older people are caused by slipping. Previous occupational safety research suggests that inadequate footwear may contribute to slipping accidents; however, no studies have assessed the slip resistance of casual footwear.
To evaluate the slip resistance of different types of casual footwear over a range of common household surfaces.
The slip resistance of men's Oxford shoes and women's fashion shoes with different heel configurations was determined by measuring the dynamic coefficient of friction (DCoF) at heel contact (in both dry and wet conditions) on a bathroom tile, concrete, vinyl flooring and a terra cotta tile using a specially-designed piezoelectric force plate apparatus.
Analysis of variance revealed significant shoe, surface, and shoe-surface interaction effects. Men's Oxford shoes exhibited higher average DCoF values than the women's fashion shoes, however, none of the shoes could be considered safe on wet surfaces. Application of a textured sole material did not improve slip resistance of any of the shoes on wet surfaces.
Heel geometry influences the slip resistance of casual footwear on common household surfaces. The suboptimal performance of all of the test shoes on wet surfaces suggests that a safety standard for casual footwear is required to assist in the development of safe footwear for older people.
老年人跌倒很大一部分是由滑倒引起的。以往的职业安全研究表明，不合适的鞋类可能导致滑倒事故；然而，尚无研究评估便鞋的防滑性能。
评估不同类型便鞋在一系列常见家庭地面上的防滑性能。
使用专门设计的压电测力板装置，通过测量后跟接触时（在干燥和潮湿条件下）在浴室瓷砖、混凝土、乙烯基地板和陶土砖上的动态摩擦系数（DCoF），来确定不同鞋跟配置的男式牛津鞋和女式时尚鞋的防滑性能。
方差分析显示鞋类、地面以及鞋类与地面的相互作用存在显著影响。男式牛津鞋的平均DCoF值高于女式时尚鞋，然而，在潮湿地面上没有一双鞋可被认为是安全的。使用有纹理的鞋底材料并未提高任何一款鞋在潮湿地面上的防滑性能。
鞋跟形状影响便鞋在常见家庭地面上的防滑性能。所有测试鞋在潮湿地面上的性能欠佳，这表明需要制定便鞋安全标准，以助力开发适合老年人的安全鞋类。
