The BlackOvis guys have a video with the Crispi rep that reviews all their boots including width. Surprisingly wide range of widths. Worth the 10 mins.
I have same problem.....very wide foot and I need a wide toe box, coupled with flat feet. After trying several boots through the years, I eventually went with Crispi as they had wide sizes. They were the only boot that fit well and required little to no break in. I would still like a wider toe box, especially with the insulated models as the insulation takes up room inside the boot. Like a few on here, I have been thinking of L&S for my next boot but I am going to have a hard time leaving Crispi as their boot works for me....why screw with something that is working....
