Generally, open lacing is less formal than closed (the kind with a "V"). In your case, you're looking at brown shoes with a lot of perforations and other details. Basically three big things determine the formality of a shoe:
1) Color - black more formal than brown
2) Lacing - close more formal than open
3) Amount of embellishments - holes, wingtips, the "'zig zag" edges, etc.
All your shoes are pretty informal. They won't be great with a conservative suit, and they will look weird with jeans (dress shoes look off when worn with jeans IMO).
Good info, but they would look weird with jeans? I use jeans 99% of the time actually, talking about very dark blue, not distressed jeans.
Ultimately, if you want a pair of shoes to wear with jeans, you should get a pair which will be at its best when worn with jeans. And if you want a pair which can be worn with a suit, you should get a pair which will be at its best when worn with a suit.
Two intended uses. Two pairs of shoes.
I get the whole desire for versatility. How we like to convince ourselves that it's the sensible approach to choosing which shoes to buy.
But it's not.
Buy one pair which can sort of work, kinda, with everything from jeans to not-very-formal suits, and you'll have one pair which is a mediocre choice for nearly everything, and an excellent choice for nearly nothing.
Whereas if you buy two pairs - one for each intended purpose - you'll have shoes which are an excellent choice for nearly everything.
Since shoes can last for decades with reasonable care, it's worth it to spend the extra money up front, and do things right.
Fair enough, in general I work at big 4 and there is no need to wear a suit at my department, so I wear jeans full time. Maybe I should get some other kind of pants as well. But that said, which type of leather shoes would be best with jeans or other more casuals pants?
