Emily, I saw some other Aerosole sandals that might be more casual/what you are looking for. I needed the ones I chose to wear with skinny jeans, to give my jeans/camisole outfit a bit of a dress up look, and be able to stand up all night. After all, this is a collective 60th birthday party for a bunch of people who look very good to start with and I want to feel "tall."
I've been drooling over those Merrells Wasp bought.
