Sims is frequently credited with inventing the first modern snowboard. He built his "Skiboard" prototype in seventh grade wood shop class in 1963, and followed with several skateboard and snowboard industry firsts, including the first snowboard with metal edges, the first pro-model and women's-specific snowboard. He was also the first to incorporate some of the earliest high-back binding systems.
Sims ran a skateshop and founded Sims Skateboards in Santa Barbara in 1976 and won the Skateboard World Championships that same year. He was featured, alongside Stacy Peralta, in the 1976 skate film "Freewheelin.' " Christian Hosoi and the late Jeff Phillips both turned pro for Sims shortly thereafter.
In addition to topping many snow and skate podiums throughout his career, including winning the slalom event at the U.S. Open of Snowboarding in 1985, Sims was a snowboarding stunt double for Roger Moore in the 1985 James Bond film "A View to a Kill."
Memories and support poured out across the skate and snow communities Thursday.
"Thank you for your immense contributions to skateboarding and snowboarding, Tom. RIP," stated legendary skateboard photographer Grant Brittain via Facebook.
"He was definitely the innovator of what snowboarding is today, and his legacy and contributions will be forever remembered and widely embraced," Steve Fisher, a former Sims Snowboards team rider and two-time Winter X Games SuperPipe gold medalist, told ESPN.com. "What he stood for and what he did for the culture of action sports is so great that it should never go unrecognized or forgotten. He's a true pioneer."
Sims also helped introduce some of the sport's first halfpipe and freestyle competitions, and was the first to sponsor riders like Craig Kelly who would go on to bring the sport to new heights and mainstream attention.
