Definitely Roughouts for comfort. I’m not sure if they’re the best, but the ATF USA made version are really very good, as are their service shoe (boot).
A different Iron Ranger experience here. I disregarded the advice about going a size smaller, bought my usual UK 8, fitted Red Wing insoles, and have a pair of the most comfortable boots I've ever owned, straight from the off.Went and tried on a pair of Iron Rangers today and they absolutely killed my arch. I love the look of them, but the pain isn't worth it. The search continues.
