Ellen Barrett encourages going barefoot to strengthen the feet and ankles on her personal subscrition website at ellenbarrett.com. Walking and dancing can help in that they move the ankles in all directions. If you'd like to try indoor walking videos on youtube, here is a link: https://www.youtube.com/c/LeslieSansonesWalkatHome/videos.
