If there's one thing that Maison Christian Louboutin comes back to time and again, it's clean, minimal lines. Take the Castarika ankle boots as an example; they're cut from supple calfskin leather, then smoothed with a round, closed toe and a square block heel. As for the notch that bites into the cuff? Well, that's designed to subtly emphasise your ankle when you slip into a midi dress, while the red lacquer underneath is to be seen when the dress comes off. Heel height 3.4" / 85m 100% leather. Made in Italy True to size Product care - The red lacquer of the soles wears out with use.
