For the past few years I've had an obsession with Birkenstocks. I know they might seem like a hippie shoe, but here in the states at least they started getting really popular with the girls in like 2014 I wanna say. And are still quite popular, at least by me.
Anyway, as (most) types of birks are worn, the inner sole part (where the bottom of the foot touches) get darker and darker, and to me that looks sooo attractive. It's all foot sweat, moisture, and dirt that does it. I've seen them almost solid black before.. omg

Does anyone on here appreciate seeing a well-worn pair of birks, with foot prints/toe prints in them? I feel like i'm alone on this sometimes but someone else out there has to love this. Here's some photos I have acquired:
