Mike Schultz, Gold Medal-winning Paralympic Champion. Mike Schultz has transformed the world of adaptive action sports in many ways. In 2008, Mike suffered a terrible knee injury during a snowmobile competition resulting in the amputation of his left leg above the knee. When Schultz could not find prosthetic equipment that would perform the way he wanted, he designed his own. Today, his prosthetic company, BioDapt manufactures limbs for fellow action and extreme sports amputees. Schultz won gold and silver medals in snowboarding in the 2018 Winter Paralympics.
