Nike has made the decision to more aggressively pursue the women's market – which already accounts for about 20 percent of the brand's $4.7 billion business in the U.S. – by creating a separate women's division. Last month, Nike promoted Clare Hamill, a 19-year company veteran, as the division's vp. Part of the strategy will be to create full-line-extension vendor shops for the apparel, footwear and equipment. However, as reported in Women's Wear Daily, the prospects are less-than-promising. One industry observer noted that Lady Foot Locker is about the only retail outlet focusing on the women's business. (For other mall-based retailers such as Finish Line and Footaction, women's goods have little major presence.)And another observer pointed out that Nike's current concept shop program is less-than-impressive. “Their concept shops are a few fixtures and a sign on the wall,” WWD quoted this analyst as saying. “They don't have enough offerings, and their colors seem to be off. You also have to search to find nice clothes. It's hard to find their stuff.”
