I felt so dumb, after finding out that the shoes I wore to work last week, were not 'Flip Flops', they are just sandals. I thought if we took the question outside of the studio, I would get some support. Nope.

According to Wikipedia:

Flip-flops are a type of sandal, typically worn as a form of casual wear. They consist of a flat sole held loosely on the foot by a Y-shaped strap known as a toe thong that passes between the first and second toes and around both sides of the foot or can be a hard base with a strap across all the toes (these can also be called sliders).
