Looks like you might have tried on several Colorados...did you find a fit difference for sizing compared to the Valdres? I find the toe box cramped on the Colorados although they are still breaking in. The Valdres for me in the same size is a perfect fit - but that toe box is much wider imo. What did you think about the fit between those 2 Crispi boot models?
I don't remember a whole lot about the valdres. I do find a slight difference between the Nevadas and the Colorados even though they are supposedly the same last. The colorados fit well while the Nevadas let my heel slip a goo amount.
I am trying some Zamberlan 1104, 1110s, and Crispi Nevadas currently. Will post an update in a week or so if I keep one. The 1104s seem promising!
