I still rate the shoe itself a 5 but contrary to the ratings (which I strictly consider when shopping) I'm returning the 10.5 I bought to maintain my actual size 10. I have actually heard reviews that these shoes run small and should be half a size up, of course I did and my foot slips which is not good for blisters. Just trust your intuition and get your real size. They really fit. I think all the reviews about getting taller just have weird foot shapes and sizes.
