In my opinion the Titan and Zzeus are fairly narrow, but are kind of high volume over the instep. I've skied in them, and I had to buckle the 2nd buckle almost all the way to make contact with the top of my foot. When checking out boot fit, remember (that in my opinion) the thing that matters is the shell shape, not the liner. The liner will pack out and change, the shell wont. I always try on different shells with a pair of Intuitions I have. Of course they don't fit great in all different shells, but it helps to give you an idea of the shape of the boot. For instance, my Intuitions were molded in my Factors and I can tell you without a doubt that the Titan is much higher volume over the instep than the factors.
