    Background

    Running shoe manufacturers designed and marketed running shoes according to motion control, stability and cushioning – the practice is to assign shoes according to plantar shapes (low, normal and high) and this is done in order to reduce the risk of injuries.

    Research question/s

    Does the practice of assigning running shoes according to plantar shape reduce the risk of injury during Marine Corps basic training?

    Methodology

    • ▶ Subjects: 1411 Marine Corps recruits.

    • ▶ Experimental procedure: All the subjects were assessed (including a questionnaire and foot examinations to determine plantar shape (low, medium or high arches)). Subjects were then randomly assigned to either (1) a group that was provided with motion control, stability or cushioned shoes depending on plantar shape (experimental (EXP) group, males=408, females=314) or (2) a control group (CON group, males=432, females=257) that received …
