Tiptoe - Literal Tiptoe

Literal Tiptoe

While it is possible to literally tip-toe, it does not seem biomechanically viable. While strong enough to temporarily support bodyweight, toes would not likely be able to accommodate the rotational forces (especially while keeping rigid, and balanced) involved in spinning. As the big toe is prominent, literal tip toe would involve raising up on the big toe, otherwise the legs would require outward rotation to make other toes touch, rotating out mostly at the hips and risking injury in the knees if not done properly.

It is an impressive stunt, much akin to finger-tip push ups, although not as visually obvious, making it difficult to evaluate, as toes are shorter and wider, making the difference between the tips and pads of the toes (as in fingers) far more difficult to discern.
