definitely bare feet, although we did have a pair of leather sole (real soft and pliable) shoes for when we would take my girls outside to walk.. But they need to learn to balance on bare feet first and strengthen their ankles. After they get it down with bare feet then you start to bring in the shoes but they should be real soft and then get harder and harder soles as time goes on and they master whatever level of shoe they are on..
