Libby Edelman is to rejoin women's footwear brand Sam Edelman to help drive marketing and licensing of the line as it expands into new markets, including intimate apparel and outerwear.

The Brown Shoe Company-owned brand said Edelman will provide "creative vision".

"Libby has been an integral part of the success of the Sam Edelman brand over the years, and we are thrilled to have her back on the team," said Diane Sullivan, president and CEO of Brown Shoe Company.

"Nobody knows Sam better than Libby, and she can help take his voice and integrate it throughout everything the brand is doing, from footwear to intimate apparel to outwear."

The couple has worked together for more than 30 years, launching the Esprit footwear business in 1983 and the Sam & Libby brand in 1987.
