I work on a salesfloor all day and found flats are uncomfortable! I need a 1 1/2 heel and a VERY roomy toe box (at least thats what the podiatrist calls it) because I have a bad bunion that adds a good half inch width to my right foot and hurts if pinched in narrow shoes.

I basically live in Easy Spirt shoes. They have these new "zero gravity" soles that are like big marshmallows. Ugly, but oh-so-cushy.
