They are shaped more like a street or trail shoe with a less exaggerated "rocker" allowing a
Bucket argument Bucket argument Isaac Newton's rotating bucket argument (also known as Newton's bucket) was designed to demonstrate that true rotational motion cannot be defined as the relative rotation of the body with respect to the immediately surrounding bodies.

Alternatively, these experiments provide an operational definition of what is
