Possible for someone to hang by their toes?

Factual Questions

This evening I was leaning back in my chair, my feet propped up against my dresser. I noticed that my toes were pretty good at clinging to the drawer handles.

It made me wonder- is it possible for someone to hang by their toes? I mean, giving enough of a foothold, could someone hang upside down by clinging on a surface with their toes?

As a kid I was able to dangle from a trapeze by my toes, but not by clutching with them. Instead, I would stiffen them and hang from them while they were extended. Not all that hard to do, once you get over the fear of falling.
