A variety of possible explanations for "Feet on Head" have been put forward.
The most common theory deems it to be a hoax.
Another theory states that it is a super-natural occurrence that defies any plausible explanation.
A third theory puts all "Feet on Head" sightings down to a form of genetic mutation or disease, stating that the sufferers should become the objects of sympathy rather than fear or disdain.
Amongst some runners, however, the theory posits that "Feet on Head" is a reaction to distressed feet. The theory is supported by the poor performance of "Feet on Head" sufferers depicted in found images - most seem to be slower and lagging, with pained expressions on their faces. Some also point out that interestingly, as running shoes improved in quality throughout history, the sightings have decreased.
