Paul Van Doren, Co-founder of the Vans brand, has died at age 90. The company, based southeast of Los Angeles in Costa Mesa, announced Van Doren's death on social media Friday but didn't provide any details.

"It is with a heavy heart that Vans announces the passing of our co-founder, Paul Van Doren. Paul was not just an entrepreneur; he was an innovator. The Van Doren Rubber Company was the culmination of a lifetime of experimentation and hard work in the shoe industry. Paul’s bold experiments in product design, distribution and marketing, along with his knack for numbers and efficiency turned a family shoe business into a globally recognized brand. We send our love and strength to the Van Doren family and the countless Vans Family members who have brought Paul’s legacy to life. Thank you for everything, Paul. You will be sorely missed."

Van Doren was a high school dropout who moved to Southern California from the Boston area. Van Doren, his brother James (who died in 2011) and business partners Gordon Lee and Serge Delia opened the Van Doren Rubber Co. in Orange County in 1966, making and selling their own shoes.

Van Doren was known for saying that the key to success was to give customers what they wanted. He allowed customers to order customized shoes and expanded the customer base by allowing various designs to be sold everywhere from surf shops to department stores.
