Flip-flops expose the toes to the air. Wiggle the Left toes. Wiggle the Right toes. Whichever feels better, whichever offends people less as toes can sometimes get rather stinky from all the dirt flip-flopped around. Flip-flops allow the toes to play together - wiggle, wiggle.

The problem with flip-flops are the toes are so unprotected. Wiggle the toes one way, then the next, and people may notice. Wiggle them together and people may question your intentions. With so much scrutiny there is no security for the bare toes.

Sneakers hide the toes. You don't know what they're doing. You have to trust the owner of the toes to tell the Truth. The advantage of sneakers is that you can't smell the toes until the shoes start to wear out. Too much sneaking around wears out the fabric, slowly revealing the hidden digital treasures and with that you smell the stench of sweaty, fungus laden toes. You can try deodorants or simply denying the smell but people know the reality. Only a new pair of shoes after a good foot cleaning will remove the stench.
