Do the Adidas F50s fit orthotics?

I have tried on some F50s at a store which were a half size too big, and the odd shape of the boot seemed to make my orthotics sit in an odd position. I thought maybe it is because it is too large, but I want to know whether anyone has had any difficulties fitting orthotics (special insoles) into F50s. My other choice is Nike CTR360 Maestri IIs, which fit perfectly.
