AE will tell you that the 5 Last is the most narrow. Most people agree. The 3 last, although it has a chisled toe, is actually wider and not quite as long. My opinion of course, but I think most would agree. Ps- I love my Neumora's, I have them in both black and brown, but the Long Branch is a fantastic casual boot. The vibram sole will be great with winter coming . . .
