Reddit mentions of Lauren Ralph Lauren Women's Cedar, Black Soft Burnished Calf, 9 B US

For shoes, maybe you could wear leather sneakers. Maybe some slip-ons like these, or converse like these. They'd allow you to run and look presentable, depending on what side of business casual your place is on (although I guess they're on the side of "safety first").

I have these in black leather. They are super comfy, and I feel like the leather dresses them up enough to wear them with some less casual things (which is important for me). The white rubber does get dirty very easily, though.
