Finally I found them!! I have called (sorry my husband has called) every store in Puglia selling D&G jr asking for this shoes and finally we found them. The price was lots of cheaper than childrensalon and childrenvillage etc too
The store is called Nascere (via Campagna Masella 16, in Aquaviva delle Fonti). Really lovely, honest and helpfull owner. Great store with a very big selection of D&G jr, Bluemarine clothes for children.
