Get the pair of red wing that fits well on you with sock, no such thing of buying reduced size so that the shoes will break into u. When the shoes seasoned, it will fit nicely on u.
For those went through NS, it is the same concept on your army boot, do u upsize to charge up the hill better?

u decide..
As for width sizes, red wing(SG) brought in D size only, I supposed due to skinny jean skinny boot?
U can try to order and sit tight if D don't fit well on u, gd shoes are worth waiting. Rem, don't buy if tight on side, your leg will suffered in long run, it should have min gap at side with sock worn.
Nowadays, hard to find size E & EE, managed to find mine by chance, I'm wearing size 9E.
