Christian Louboutin Mousse heel sizing help

I ordered a black pair online...Im usually a size 38 and a bit wide at the toes..the problem is they only have the black in 38 or 39 not even a 38.5...so what should I do...will they be tight at the front and pinch if I get a 38 or will it be too big in 39?
The style is a runched chiffon.
Please help thank you.
 
Chanel - I found that the mouche crepe chiffon VP styles were pretty TTS which is strange because most VP styles generally run small. I think it is because the chiffon is a very giving fabric. My approach when ordering online is just to order both sizes that I think will work for me and then return the ones that do not fit well. Good luck!
