Dang, those look great after conditioning them!
I've had mine for a while now and have not yet cleaned or conditioned them. I haven't really worn them that much either, though. The fit isn't quite right for me. The toe box is pretty wide, and yet somehow my small toes rub against it. It's like it curves inwards too quickly on the outer edge of the toe box.
I haven't worn them since maybe February; I'll give them another shot and see if something has somehow changed since then, but it seems like they just aren't the right shape for me.
