Hey man thanks for taking the time to get a photo! I was also considering indigo rub off since my current light tan belt is getting really grungy. Any waxy leather treatment ought to work, right?Ed: I should add, the 7 hole approach makes me really happy too; I have at least one belt kicking around that only had 3, now completely worthless unless I get a tapeworm.
A less fancy/more trashy collection:
Bog standard Doc Marten 1460, 90s/my highschool years vintage
DM 1914, made in england version
Demonia unknown model, glossy burgundy, faux steel toe
LL Bean Kata's
RW Iron Rangers (current fav, love the hawthorne leather)
Chippewa engineers (forget the model)
