I recently made a post on some cute sandals. I always wear a non athletic sandal with a back. Yes, I care about I represent myself, and a sundress, sandal, no bags and a widebrim straw hot are great for staying away from that melty/winkly/sweaty look. I have great feet though I do have some small foot drop in my left foot which sometimes still arises when I'm very tired and I'll switch to wedge sandals, sounds weird, but it REALLY helps my keep my gait normal. The wedge does the work in keeping your foot heel toe. It rarely bothers me anymore, but I keep a pair of espedrialles for just such an occasion - which are also a great choice. I used to be able to do backless sandals, but they can be problem for me. I see people wear them all the time. Everytime I've worn professionally fitted, moisture wicking or cute sneakers I've gotten horrible blisters in a few hours. My feet are really narrow and skinny, or perhaps really sweaty? Anyhow, wear what you feel great in! My feet really never hurt.
