Odd Look but Great for Flat Feet
I've used these PUX shoeless arch supports previously - and really find that they help.  I tend to have plantar fasciitis on occasion, and these help to provide arch support when I'm walking around the house without shoes.  They may seem sort of weird, but they really do help. My only caveat is that they do slide a bit if your foot gets sweaty - e.g., I've used them when working out.  Still, they definitely help for folks with flatter feet.
