Bruce Katz, who with his father started the Rockport Shoe Company in 1971 and established walking shoes as a vibrant footwear category, died on June 26 in Greenbrae, CA. He was 75.

In the late 1970s, Mr. Katz developed a comfortable, casual shoe that became the foundation of Rockport’s business. The company was a pioneer in the use of features like cushioned, removable orthotics (foot beds) to provide internal comfort and structure. In 1986, Reebok acquired the company for $118.5 million.

Then, 27 years away from the shoe business, he returned, starting the Samuel Hubbard Shoe Company, this time using more luxurious European leathers and advanced technology, with a continued emphasis on lightweight, casual comfort.
