UP SHOES_ BUBBLES by CLAUDIA CIVILLERI. The design of the BUBBLES model, always in the UP SHOES series, is even more special. In this article the vamp is completely covered with bubbles, made in soft-calf leather. The construction of the shoe is very particular, because the vamp is made from a single piece, with the toe opening. The shoe can be worn also with a colored sock, in contrast with the color of the vamp, for a sunny winter.
