Just order em from Backcountry or the like so you can return em. I got my last pair from Moosejaw for 20% off. Rei the time before that for 20% off. Both allow me to return them. Rei even used no questions asked. I say go with Rei if you are unsure.
With that said i would say i have a narrow heel and a average to wide forefoot but far from a wide foot!? I also wear La Sportiva Ice Climbing boots "two pair now" and i have no heal lift at all in any of their shoes. Imop the heel is cut for a narrow heal. My forefoot is neither narrow nor is it wide but it would be more on the wide side if anything. I have room to spare in this shoe around the ball of my foot area where my foot is widest in my pair i use for trail running sockless. Not much but enough my foot can flatten out.
I also have a pair sized up for use with a heavy winter sock as approach and winter running climbing shoes and those have less extra room in the ball of the foot area but still some even sized up. I will say this though, the La Sportiva toe box does seem to tapper in after the ball of the foot on the outside edge toward the front of the shoe quite a bit. This could cause the outer and little toe to rub if you size them too small or had a wide foot i would think.
Great shoes for $120 on sale they are a winter gift to a trail runner.Get the hobnail kit. That you gotta order off the La Spotiva web site.
