I played rugy from my 20th to 35th year of life. My place was winger for which you had to start quickly and run very fast. What I did. Someone once told me that I was sprinting like an Indian runner. Without heel contact, only on the fore-/midfoot; untrained only on the short distance. Now, after being ‘foot-active’ for almost a whole life, I question the general naming and definition of pronation as an abnormality or illness.
