Nine West and New Balance are teaming up to get a slice of the fast-growing market for fashion sneakers.

Nine West, a unit of Jones Apparel Group, and New Balance said the new line, backed by a marketing blitz, will launch in spring 2009.

“Marrying [high] tech [materials] with fashion is a void in the market that we aim to fill,” Andrew Cohen, CEO of Jones Apparel’s footwear, accessories and retail divisions, told The Post.

Indeed, sales of so-called “low-performance” sneakers, which typically emphasize color and design over factors like support and durability, surged more than 12 percent last year, according to consumer research firm NPD Group.

The partnership is a first for New Balance, which traditionally develops its merchandise internally, product manager Alana Choquette said.
