I own an older pair of Crispi Nevadas (2012-2013?). My foot width is a narrow D with a high arch and low volume. They fit me pretty well with proper insoles and they've been used and abused for many years, they're since retired to hunting on the plains.
I do not consider the Nevada to be stiff at all, for comparison, the new Crispi Thor has a much stiffer sole. I have been wearing Lowa (Tibet and Cevedale Pro) boots the last few seasons and I'm much happier with them but it all depends on your expected use and application. For me, Lowa's lacing system is simply better. No experience with the Ranger but I feel Lowa offers more bang for the buck at similar price points.
