Sidi wire vernice, the fit.

Hi guys my first thread here. I'm a relatively new rider and I've treated myself to some sidi wire vernice shoes. There probably much better than I need but I do like nice things so went for them.
I'd heard the fit of the sidis where narrower but with wiggles free returns I thought I'd give them a try.
Width wise they are fine much the same as my current specialized sport shoes but I have a little more room in the toe department I'm tempted to send them back and try a size smaller but I'm wondering if people like a little room for the toes to move around? Are riding shoes meant to be a snug fit all the way around? There's no slip on the heal I'm just unsure what to do. Any help would be appreciated as I'm sure you can imagine spending over £200 on shoes you want them to be right.
