The following study proposes to investigate the injury risk associated with the use of a new category of running footwear: the minimalist shoe. A group of experienced adult male and female runners with neutral foot types will take part in this study. All participants will be randomized to receive one of three different shoes: a full minimalist shoe (Vibram 5-Fingers), a partial minimalist shoe (Nike Free 3.0) and a conventional neutral supportive running shoe (Nike Pegasus), while training for a 10k event over a 14-week period. Outcomes to be investigated are pain, footwear perception, and number of injury events.
