L size Used once at an event. It's thick, so I bought a lot of things, but this was the best. I sewed on some jewels for decoration, so there are needle marks. Thank you for your understanding. Made with thick Lycra fabric. With shock-absorbing material, it's perfect for dancing barefoot. Reduces foot fatigue and prevents corns and calluses caused by dancing. The sole is suede, so it conforms to the shape of the foot, doesn't hinder foot movement, maintains moderate grip, and is resistant to friction, protecting the feet. Material: Lycra, Microfiber (sole)
