The Cristallino is a great slip-on ankle boot. It's made of leather and has elastic goring on both sides and slightly ruched finish of the upper material which allows for a flexible fit and an easy on-and-off. The shock-absorbing thermoplastic elastomer sole has a stacked heel with a wood effect insert. This boot helps you look put-together and pairs so well with a casual outfit like your favourite sweater and leggings.
