The California-based affiliate of German shoe manufacturer Birkenstock on Wednesday revealed it has become fully employee-owned.

The company said in a short press release the final transfer of shares from Birkenstock USA’s founder, Margot Fraser, came via an employee stock ownership plan.

Fraser recently transferred the remaining 60 per cent of the company's value into the ownership plan. The company is famous for its huge range of colours and styles of its sandals, shoes and clogs.

"Birkenstock has always been a special company that focuses on its employees," said Fraser. "I wanted to make sure the future of the business was modeled after the past, keeping our core values and operating mantra intact, and I know it will be in good hands.

"I am thankful for all the hard work and effort every employee has put into this business, in the past, and moving forward into the future."
