I've got longer, but probably narrower, feet than you. I have an assortment of la sportiva shoes that fit well. Often within half a size of the largest they make (EU 44.5 to 45.5). Those shoes probably aren't wide enough for you, but I'm sure there are other options. I never found a Scarpa shoe long enough to get my feet in (though I understand they may exist).
Ultimately you just need to try on as many shoes as you can, see what works.
