Conservative: John Lobb, Alden, Allen Edmonds, Crockett & Jones, Vass, etc.
Sleek: Gaziano and Girling, Corthay, Berluti, Bontoni, Sutor Mantellassi, Carmina, etc.
Question has way too many variables. I want to say conservative but I wear one brand on the list and really dislike 2 others.
And I don't find all of the 'sleek' brands to be so over the top.
I think I would say, I like traditional style shoes done with elegance. The wheel is good enough, I just want a racing slick.
Not that I don't fancy some new creations I see but most appear to be wacky for the sake of wackiness.
I think another issue I have with some of the one offs if you move beyond the 'sleek' into the bespoke designs is that if a shoe requires a limited range
of outfits for use, I cannot value it as highly as one that has a larger range.
I love the 'sleek' lasts in your 'conservative' brands, i.e., JL 7000/8000, C&J 348/358, Vass U. And I love the 'conservative' lasts in your 'sleek' brands, i.e., G&G GG06.
