摘要

由于滑倒和跌倒造成的创伤性伤害在印度和全球都很普遍。这些伤害不仅影响生活质量,而且造成巨大的经济和赔偿负担。由于鞋和地板之间的牵引力不足,通常会发生无意的打滑。由于低收入和中等收入国家的经济条件,公众倾向于购买低成本的鞋类,以替代昂贵的防滑鞋。在这项研究中,研究人员考虑了10种售价低于25美元的高销量正装鞋。这些鞋子在三种常见的干地板上进行了测试,并在受污染的普通地板表面(即水和地板清洁剂)上进行了测试。采用仿生防滑仪对鞋的牵引性能进行了量化。研究发现,大多数正装鞋在常见的湿滑表面上没有防滑性能。外底较软的鞋子防滑性能增强(R2 = 0.91)。与其他鞋相比,鞋跟区域没有鞋底的鞋大底显示出较差的牵引性能。在干滑和湿滑条件下,表观接触面积是影响滑移风险的重要指标(R2 = 0.88)。这项研究有望帮助公众和鞋类制造商选择更安全的鞋子,以减少滑倒事故。

Traction Performance of Common Formal Footwear on Slippery Surfaces
Traumatic injuries caused due to slipping and falling are prevalent in India and across the globe. These injuries not only hamper quality of life but are also responsible for huge economic and compensation burdens. Unintentional slips usually occur due to inadequate traction between the shoe and floor. Due to the economic conditions in low and middle-income countries, the public tends to buy low-cost footwear as an alternative to costly slip-resistant shoes. In this study, ten high-selling formal shoes under $25 were considered. These shoes were tested on three commonly available dry floorings and across contaminated common floor surfaces (i.e., water and floor cleaners). The traction performance of the shoes was quantified by using a biofidelic slip tester. The majority of formal shoes were not found to produce the slip-resistant performance across common slippery surfaces. Shoes with softer outsoles exhibited increased slip-resistant performance (R2 = 0.91). Shoe outsoles with less-to-no treads at the heel region showed poor traction performance as compared to other shoes. The apparent contact area was found as an important metric influencing the slip risks in dry and wet slipping conditions (R2 = 0.88). This research is anticipated to help the public and footwear manufacturers select safer shoes to reduce slip-and-fall incidents.
