Replying to Full Tilt Camo

I have a chance to purchase some Full Tilt boots from 2008, the Camo model. What i wanted to ask is how heat modable(in terms of expanding) are they? I only have an option of purchasing a size 25. and when I went to my local shop to try on the full tilt boots, the smallest size they had were size 26s. so i tried those on and they were too big.

So I asked the guy if the women's boot shell were different from the mens bootshell and he said no its mainly the liners that are the difference. So i tried on a womens size 25.5(with the intuition liner just to see how it would fit) and it was way tight. but when i put my foot in the bootshell, it was perfect more or less.  the bootfitter told me that the shells are the same size. for example, size 25 and 25.5 have the same shell but different liner. size 26 and 26.5, same thing. -is that true?

some info about me if it helps
-i currently have these cheapo nordica boots from sports authority(i know bad decision to buy from them) and they are size 25.5 and they packed out WAY too much.
