Efficacy of Shoes and Boots in Preventing Motorcycle-Related Ankle Inversion.
The current investigation explored the potential prophylactic effects of shoes, work boots, and motorcycle boots in reducing ankle inversion associated with ankle sprain. While the majority of previous research has investigated the effects of protective equipment in crashes, rates of lower extremity loading in emergency stop contexts are comparable to jump landings and may induce frontal plane loading that could lead to ankle injury. Fifteen adults wore athletic shoes, work boots, and motorcycle boots in a motorcycle drop task. Motorcycle boots significantly (p = 0.03) decreased peak ankle inversion angles by 3.6 degrees, but also increased (p < 0.01) vertical ground reaction forces by 0.21 bodyweights compared to the other shod conditions. Overall, it is suggested that motorcycle boots can potentially protect motorcycle riders from both crash-based and emergency-stop injuries.
