Quilted Velvet Gondoliera FlatsBeautifully crafted in black velvet, these Bottega Veneta slip on ballet flats are sure to add a sleek style to your party and special looks. Featuring the iconic and instantly recognizable intrecciato quilt design all over the surface, they have also a lovely leather lining and insole. I had them resoled as the leather sole was super slippery, which unfortunately covered up the sizing but they are a European 37 or UK 4 and the insole length is 24. 2
