In reply to Radioactiveman:
I 've just swapped from trango evo gtx to the Nepal gtx. My feet had spread making my old trangos a tad to small and my toes were hitting the end! Plus i had some replacement orthotics which were slightly more volume so new boots required. My trangos were 41.5 and my Nepals are 42. Much better fit plus space for my new thicker orthotics. I think a 42 trango would not have been big enough.
So I would say the Nepals are bigger for the same size, by how much is hard to say, maybe at least 0.5 of a size?
Not very helpful but some evidence of size difference
