If you say so. I've had a new pair of boots every season for the past 6 years. Every pre-season I go to 3-4 local shops and try on everything in the medium and stiff categories. Brand new models/brands, old models (just in case anything changed) and in +/- 1/2 sizes. I'm referring to width of the toebox though, not the heel.
No, Vans are only "average" width in the heel (not wide... but not really narrow either). I also try a lot of boots/brands each year. A couple of shops guys keep recommending Vans to me as being narrow... but I never found the Vans to be that good. Either none of them actually have narrow feet, or they just aren't aware of Nitro boots (or both).
