Reebok executives do not like to hear their stylish athletic shoes called" footwear for yuppies". They contend that Reebok shoes appeal to diverse market segments, especially now that the company offers basketball and children’s shoes for the under-18 set and walking shoes for older customers not interested in aerobics(健身操)or running. The executives also point out that through recent acquisitions they have added hiking boots, dress and casual shoes, and high-performance athletic footwear to their product lines, all of which should attract new and varied groups of customers. Still, despite its emphasis on new markets, Reebok plans few changes in the upmarket (高档消费人群的)retailing network that helped push sales to $ 1 billion annually, ahead of all other sports shoe marketers. Reebok shoes, which are priced from $ 27 to $ 85, will continue to be sold only in better specialty, sporting goods, and department stores, in accordance with the company’s view that consumers judge the quality of the brand by the quality of its distribution. In the past few years, the Massachusetts-based company has imposed limits on the number of its distributors (and the number of shoes supplied to stores), partly out of necessity. At times the unexpected demand for Reebok’s exceeded supply, and the company could barely keep up with orders from the dealers it already had. These fulfillment problems seem to be under control now, but the company is still selective about its distributors. At present, Reebok shoes are available in about five thousand retail stores in the United States. Reebok has already anticipated that walking shoes will be the next fitness-related craze, replacing aerobics shoes the same way its brightly colored, soft leather exercise footwear replaced conventional running shoes. Through product diversification and careful market research, Reebok hopes to avoid the distribution problems Nike came across several years ago, when Nike misjudged the strength of the aerobics shoe craze and was forced to unload huge inventories of running shoes through discount stores. Although the Reebok Company has solved the problem of fulfilling its orders, it ______.

A. does not want to further expand its retailing network
B. still limits the number of shoes supplied to stores
C. is still particular about who sells its products
D. still carefully chooses the manufacturers of its products
