Running shoes and running injuries
Over the past 40 years, the frequency of running injures has not changed. Minimal evidence exists to suggest that pronation and impact forces are significant risk factors. Two new paradigms for predicting running injury are the ‘preferred movement path’ and the ‘comfort filter.’
The incidence of running injuries has remained unchanged over the past 40 years, despite so-called advances in shoe construction and technological innovations. This leads to us to question whether or not running shoes influence the frequency of running injuries at all? The following article investigated five components related to running injuries and shoe selection: (1) changes in injury prevalence over the past 40 years; (2) the association between sports shoes, inserts and injury; (3) previously researched mechanisms of injury related to footwear; and two new models for injury prevention (4) the ‘preferred movement path’ and; (5) the ‘comfort filter.’
The researchers were unable to identify any relationship between impact characteristics and ankle characteristics in terms of running-related injury. The two latter mentioned models, the ‘preferred movement path’ and the ‘comfort filter’ provide a hypothesis to elucidate a relationship between footwear and injury. These both suggest that a runner intuitively selects a comfortable product using their own comfort filter that allows them to remain in the preferred movement path.
It is proposed that this may automatically reduce the risk of injury and may explain why there does not seem to be a secular trend in running injury rates.
