Final answer:
Christian Louboutin's use of a few selected retail outlets for selling their products exemplifies Selective Distribution. This is a strategic approach where products are available at a limited number of specialized vendors.
Step-by-step explanation:
Christian Louboutin's strategy of offering shoes with a trademark red sole exclusively at a select few Neiman Marcus and Nordstrom locations, as well as at other high-end boutiques, is an example of Selective Distribution. This type of distribution strategy involves a limited number of outlets in a geographical area to sell a product. It sits between the extremes of intensive distribution (used for mass-market products) and exclusive distribution (where only one retailer in an area sells the product).
