Thanks for sharing. I know what you mean now about the Viberg heel. Much more different than I would have thought.
For reference, I just asked a friend to take some pictures to compare the Whites & Viberg heel. He recently took ownership of the Viberg Service boot (mocha CXL) and has had the White's Classic Work boot (brown CXL) for a couple of years. I just sent him this link so perhaps he can chime in on any comfort and aesthetic differences.
The last thing I need is another pair of work boots but Whites & Viberg are just in a completely different league than my original brown Wolverine 1K's and my RW Beckman/9011.
I was all set earlier this year to build a pair of SD's in brown dress & cuban heel when my wife surprised me with a pair of RW Beckman's out of the blue. I was so shocked that she remembered which boot. Maybe she listens to me after all when i'm droning on about apparel & footwear . I figured my boot needs were taken care of but I keep coming back to the SD. It's a curse.
