Sometimes you see a build that really gets a certain look just right. I just came across these on Eastwestapparel's site, and I think the description is exactly right, that it catches perfectly that "old school hobnail look."
SD on the c461 last, double leather sole, black dress leather.
One thing: If you're a White's wearer you will really miss the arch support. My experience is that, other than the 310, Vibergs have essentially none. And that combined with their tendency to often send out boots with a built in pronation (inward lean) can be a problem for those of us with high arches.
I can't quite figure out what that is, but if it's hard plastic material it seems unlikely that it will wear down. The question is whether it rubs your heel and bothers you. If so, then I'd say it's a problem. If not, then no big deal since it's not otherwise visible.
