Grishko's ProFlex is made on the same last as the 2007 with a unique design allowing it to be very flexible, comfortable, and quiet. A new, more flexible material used for the inner sole helps to save muscle energy while dancing. The ProFlex will help develop strength in toes and lift so one does not sink down into the shoe. Its flexibilty fills the needs of dancers at both the beginner and professional levels. ProFlex is lightweight and comfortable, with a somewhat tapered box and medium platform, supportive yet non-constrictive medium-height U-shaped vamp, and 3/4-length pliable shank. Shank: Flexible. Suede sole; cotton drawstring; ribbons not included.
