I have three pairs, and wear them everywhere, with everything. Yard work to (casual) weddings, so does the hubby. They are comfy and cute. The church-key is so well placed it never digs into floors/ground, safe enough for boat decks. I would also like to point out to all the skeptics that the bottle opener only touches the bottle cap, not the bottle. So shake your shoe off, open that tasty non-twist off, and drink on!
