Cuffed Sandals

I just received an email from Piperlime.com regarding these new trend in sandals. In the email they called them Cuffed Sandals and on the website they are called The New Gladiators.

To be honest with you, I think they look super cute, but I just don't understand them. Why would I choose to wrap my ankles? It feels wrong to wrap my ankles with leather or anything in the Summer. It just doesn't make sense.

It looks constricting... and it kinda looks like a straight jacket situation... Doesn't it?
But, I see everyone wearing them. What do you all think?
