• Description:
  Falls are the leading cause of emergency department visits. Slipping on liquid contaminants is a common cause of falls. Footwear has demonstrated promise in preventing these slips. The mechanics of shoe friction in the presence of liquid contaminants is multifactorial (Chang et al., 2016). Fluid pressurisation driven by the squeeze-film and wedge effect can separate the surfaces and reduce friction. In wet or oily conditions, friction forces originate mostly from hysteresis friction, defined as energy loss in the shoe outsole caused by sliding-induced load cycling. These mechanics provide guidance for designing shoes with improved friction. Description provided by NIOSH
