I'd say "no," too. Yes, they're simply designed, like an unaddorned calf pump, but a tux is the outfit with the least amount of flexibility. Also, it's supposed to be the most elegant of outfits (arguable, of course), and boots would detract from that. Nice footwear, though.
As boots go, these are quite elegant. And back in the day, boots were what one wore with evening dress. The dinner jacket was a rebellion against all that, however, and it seems a bit incongruous to wear relatively heavy shoes with what should be a light and elegant indoor ensemble. But this is one of those areas where someone could get away with bending a rule. Sort of like the Duke of Windsor's suede shoes with chalk stripe suits. I'm sure not the right guy for this project, but you might be.
Boots are appropriate with white tie but not black. When white tie evolved men wore boots and not shoes. By the time black tie arrived, evening boots were in the minority. Those particular boots, though great looking generally, wouldn't work for me with formal wear.
I am not a big fan of pumps or patent leather oxfords. I've got a pair of black Alden cap toes that could (barely) work with the tux if I really polished them up, but cap toes are kind of inappropriate and Alden cap toes even more so since they're so clunky. I think I'm going to have to go searching for some plain black uncapped calf bals, maybe a wholecut. I hate buying black shoes since I almost never wear them.
