As the company grew, Herman Delman’s personal role in design diminished. Another critical factor in the company’s success became the selection of talented designers who created an extensive variety of fashionable shoes. Designers employed by Delman Shoes over the years included Herbert and Beth Levine, Kenneth Jay Lane, and Howard Davis. The "Delmanette" line of youthful styles, introduced in 1949, featured the work of women designers such as Bernice Shaftan. Renowned footwear designer Roger Vivier worked for Delman from 1938 to 1953, in which year Vivier began designing the Delman-Dior line, produced in partnership with French couture designer Christian Dior. Vivier returned to Delman in 1992.
