Repetto La Carlotta Pointe shoes- work for about 20 minutes to see if they would work for me in studio. Never sewn- just tried on at the barre between classes for 15-20 minutes Soft shank and medium box. Size 39 (5 1/2) Shank still has lots of life in it and box as well- wings were too short for me and the vamp too long. I adore Repetto shoes they are so well made and really mold to the foot after a few classes. fThe Carlotta pointe shoe, inspired by Repetto's special-order pointe shoes, is the leading pointe shoe of the Maison Repetto. It’s the result of research that was realized in collaboration with the Technical University of Compiegne in France. Thanks to a special material inside the pointe shoe it is less noisy than other models. While meeting the requirements of professional dancers, The Carlotta, with its high vamp and reinforced wings, provides a beautiful line and comfort. A large variety of options are available to fit every dancer. Selling for a discount since wearing them at the studio caused slight marks on the of the platform and trying different padding with them likely softened the wings and shank. Retail is $115 plus shipping, selling for $25
