Colonna flats are characterized by the classic round toe of ballet flats. Made of suede with cotton lining, soft leather insole and a 0.5 cm low heel, these shoes are incredibly comfortable. The cut is embellished with tone-on-tone grosgrain and the thin cotton string is adjustable. Dark gray suede ballet flats are a closet staple. They look flawless with a formal suit, bon-ton paired with a modern dress, and fresh and glamorous teamed with a pair of black distressed jeans and either a maxi sweater or an oversized shirt.
