flip flops would be a disaster for me, my feet are so numb that i wouldnt be able to retain the thong of the flip flop between my toes, and i wouldnt feel when they had fallen off while walking. That has already happened to me several times with even regular walking shoes. I have to retrace my steps back to find my shoe. i wear new balance walking shoes now with velcro straps so that i can adjust them more easily during the day and for retention.
