Christian Louboutin built his entire brand around one idea — the red lacquered sole, trademarked since 1992. The Bianca is one of his most dramatic silhouettes: black suede, over-the-knee, platform sole with a sky-high heel that still manages to feel wearable because the platform takes the pitch out of the incline. The kind of boot that does the talking before you say a word. Soles show wear, uppers are in good condition. See pictures for details.
