I use Foundation and haven't had to use any <br/> with forms, nor have I even thought about it.

Ah, this is my error, sorry.

I went back and checked; it was actually the lack of any wrapping container that was bothering me; <label><input><label><input> etc.

(Unless you're very careful with the styling it gets to be a pain in the bum to include non-standard chunks of markup underneath some elements, particularly if you want to arrange the label on the left and everything else on the right.)
