Replying to Full tilts running 1/2 a size small?

Today I was being taught how to fit someone for a boot at my new job working at my local shop. I put on some full tilt classics and they told me that my toes should barely touch the front of the liner when standing, and be very close, but not touch when in stance. I put on some 28.5's (my current boot size) and they touched the front of a liner with a bit of pressure, and touched lightly when I was in stance. I tried on the booters in 28.5 also, but my toes touched the liner as a properly fitting boot should, but I had more pressure points and it just didnt fit as well as the classics. We didnt have any 29's in the classics so I couldnt try those on. Do you think that if I ordered some 29's off of the internet that they would fit fine? The boot wasnt putting an incredible amount of pressure on my toes, but enough to the point I would feel like I might get some toe bang on hard landings.
