Subtle Parisian style at your feet. 【Material】 ・ Ballet flats finished with the Bolognese construction method, characterized by a snug fit. ・ The upper and lining (the inside of the shoe, the part that touches the foot) are molded in close contact, providing a comfortable fit as if gently wrapped in a single piece of leather. ・ Lightweight design due to the absence of an insole. ・ Excellent flexibility and resilience of the sole. ・ The insole mainly uses recycled plastic bottles. 【Design/Silhouette】 ・ Lightweight and soft AIRina ballet flats. ・ Assorted types with different materials for each color. ・ Design with a subtle square toe. ・ The instep is slightly deeper, providing good foot coverage. ・ Flat type, easy to put on and comfortable to wear.
