How it works
Dorsiflexion is a foot position whereby the heel is placed lower than the forefoot. This biomechanical principle has been used for years by physiotherapists, by shoe makers trying to reproduce the natural feeling of walking barefoot in the sand, by Japanese traditional medicine to activate blood circulation in the legs. It is therefore not a new concept. What's new are the scientific studies proving that placing the foot in dorsiflexion provides for greater benefits than regular athletic shoes in terms of training, performance and health.
