Barely worn MBT sneakers with box and DVD

Barely worn MBT Masai Barefoot Technology walking sneakers. “Physiological footwear” MBT sneakers are supposed to help you walk better and improve your posture while standing. They come with a DVD and guide. I wore a few times then realized they’re a bit big on me. :-( They were $245! the soles and exteriors look brand new! (but they have a slight bit of wear inside near the heel.)
