I'm in need of opinions ladies!

My husband purchased me my first pair of YSL Tribute sandals, but I'm torn on whether they're too small or not.
Please forgive me in advance for the nasty feet.

I'm in dire need of a pedicure.
And please excuse my ugly towel. I didn't want to scratch the soles of the shoes, so I threw one of our rag towels down to get better photos near the mirror.
Anyway, here are some shots of the Tributes on my feet:
I generally wear a US12 and the shoes are a 42, so I don't have the option of sizing up. They're not uncomfortable, but I feel as if my left toe hangs over the footbed just a tad and I wonder if the shoe does or will look too small to others.
Thanks!
