I'm selling these because my child has outgrown them. The soles show minimal wear. There is some scuffing on the sides, but they are still in good condition and can still be worn. I appreciate your understanding. Quoted from New Balance: ↓ ● Barefoot Sensation 【For children, being barefoot is best】 Stimulation to the soles of the feet develops the nerves that control motor skills. Because the time spent setting the heel is short, braking is less likely to occur, allowing for efficient movement. It maximizes the foot's original functions. 【Barefoot sensation shoes NB PREMUS】 The last is designed with a small difference in height between the heel and forefoot, making it closer to a barefoot state. The wavy insole promotes stimulation. It does not hinder the movement of the foot. Lightweight and flexible sole.
