On the February 4 installment of KBS 2TV's 'Vitamin,' Nine Muses' Hyuna talked about the adverse effects that wearing heels for a prolong period of time had on her body. 

MC Lee Hwi Jae asked Hyuna and Minha, "You guys dance in high heels?" Hyuna responded, "I've been wearing heels for ten years, ever since my modeling days. The fourth toe on my left foot became completely deformed. My left pelvis has also taken a toll; it makes a creaking noise and feels like it's falling out."

A rehabilitation medical treatment specialist told her, "If you walk around in heels, they don't absorb shock. The shock could go straight up to your knees and waist. There are research results that state when you wear high heels, your gait could become similar to that of an arthritis patient." 

It looks like the Nine Muses girls may have to consider dancing in sneakers from now on for the sake of their toes and pelvis.
