Koolhaas about the collaboration: "Iris was introduced to us after I admired her fashion collection. At our meeting, I offered making shoes for her. For designers shoes are usually last and often they do not have the right tools to make them: shoemaking is an art.The Iris van Herpen X United Nude product is a glamorous ankle bootie with smooth round lines and golden leather detailing on the front and back of the shoe, with three-dimensional characteristics. Transparency, reflections and movements create the effect of visual estrangement. The construction of the shoe is so complicated and precise that each pair is 100% hand-made with the highest grade Italian kid leather available.
