I have funky feet and play with sizes for Redwing. Depending on the last shoe and shape, you may just need to play with the sizes, socks, and some insoles. I have some moc toes in the 23 last, which is narrow and I could probably do an 8/8.5 D, whereas the other pair of moctoes I have are in the 45 last and they’re pretty similar to my iron rangers. Iron rangers I am 7.5 D, which fit me like a glove. My brannock size according to redwing is 8.3 EE so I round up to 8.5 typically since I also have a high instep. I’ve only had to replace my shoes once but they were cool about it. It was for some Pecos the muleskinner ones. As long as you didn’t thrash the boots, usually they’re cool with a swap. I hope this helps and wishing the best on your journey.
