Feistmantl also won five medals in the men's singles event at the FIL World Luge Championships with one gold (1969 - the first Worlds to be held on an artificial track, at Königssee), two silvers (1959, 1970), and two bronzes (1967, 1971). He also won two medals in the men's doubles event at the FIL European Luge Championships with one gold (1967) and one silver (1962). After his 1969 World Championship win, he donated the medal to the Polish team after their luger Stanisław Paczka had been killed whilst in competition at the Championships: Feistmantl stated that he "wanted to set a positive example". That year the International Olympic Committee awarded him a Fair Play Prize for his gesture.
