I bought these shoes because they were supposed to improve posture just by wearing them, but the fit wasn't right for my feet, so I ended up cutting the end of the Velcro strap on the toe side. I think they might be good for those who want to try them, but please refrain from purchasing if you have any concerns. Just by wearing them, you can walk like a model! Just by wearing and walking, they improve posture and support muscle strengthening! With their unique sole, they control your center of gravity and stimulate your core. By strengthening your core, which is the foundation of your body, it leads to improved bodily functions. Perfect for casual wear ◎ They are a sports type. Thank you for viewing. *Please read the profile before purchasing*
