British made 'country' shoes and boots tend to come with a storm-welt, or, more rarely, are made veldtschoen. So it's not 'extreme waterproofing' - it's simply as standard. I really don't see the point in spending a lot on these boots if they're going to crap up after an hour or two.
Given the evident quality, it would have made far more sense for Wolverine to make them veldtschoen - it would make them really interesting and unusual boots - and correspondingly increase their sales. I also don't understand why they didn't put a rubber sole unit on them. No half sizes, which is again pretty crap.
i'm pretty sure they have half sizes. i own a 7.5
