I used to own one or two pairs of shoes at a time. Big, clunky, super-comfy shoes, sandals when I could get away with it. I wore them until they gave out entirely. Then a previous job made me hyper-self-conscious about appearance and social signals, so I changed.
For about a year, I wore just plain old ballet flats that you could buy at any shoe store. Then I noticed a large, soft bump developing at the top of my foot. Turned out ordinary ballet flats are both too narrow and not supportive enough for my feet.
I want people like me to be able to easily find arch-supportive flats. So here are my personal favorites, along with other options that might work for you.
