Do these fit....

Krazykuda

You have really done a number on me, no pun intended.
I'm not sure now if that's a 5 or a 6, I have the same pic you are looking at and wishful thinking is wanting me to believe that it may be a six now but Damn I'm not sure and I don't want to buy them and they don't fit.
Is there any other way I can find out ?
Thank you.
