If you've been reading the online consumer reviews concerning these boots then you've seen comments to the effect that they are sized about a half size larger than stated. It's actually weirder than that. I wear a 13 in virtually all hiking boots but can easily get away with a pair of 14s with heavy socks -- indeed, I'm a happy owner of two pairs of Lowa in size 14 so I thought these in 13 would be perfect. However, the Lagori (and from what I can ascertain, the entire NW line) doesn't actually provide a 13.5" boot when the label says 13" -- they're more like 13" with regard to the toe box and 15 in the heel.
The amount of heel lift with these boots was really excessive with thin, medium, heavy, and even extra-heavy mountaineering socks from Darn Tough. The only time I could eliminate most of the slippage was with my thickest socks and laced up so tight that they became torture chambers. There was just no way to make them fit. I couldn't go down to a pair of 12s because 'boot bang' was going to be an issue. Pretty disappointing to say the least. But definitely give the Lagorai a spin because if you find a pair that fit you're in for a real treat.
