I have my eye on some used Kryptons but I've been told they are best suited to a narrow foot. I think I have a slightly wider than D foot. I fit comfortably in either D or E width shoes. When I measure the outside points of my foot, I get 4.25 inches or 10.795cm.
Dalbello lists their Krypton Cross as having a 98mm last. Is my foot too wide for this boot?
