Guide to picking shoes for work/long nights:
-wedges work well
-get shoes that aren't structured with cheap materials that will dig into your skin
-don't purchase/wear shoes that have a rounded front base
-thick, tapered, chunky heels make for an easy to wear pair
-shoes with a platform prevent direct sole to floor pressure
-flats must have support or else they will kill
In my opinion, it's better to wear a pair of shoes you will survive all day or night in rather than being one of the girls that take off their shoes and walk barefoot in public.... Eeeek
