Recommended for professional dancers, students of high school, and amateurs. Also recommended for less trained feet. Shoes have a U-shaped medium vamp, medium platform and are based on the «Grishko 2007». PRO-FLEX fits all types of feet, and they are specially recommended for performances where flexibility and quietness are most important. The sound deadening materials integrated into the pleats beneath the box make the shoe super silent. New, more flexible material used for the inner sole helps to save muscle energy while dancing. The shoe is extremely flattering, supportive, flexible and lightweight.
