Freestyle competitors Anna Gasser of Austria and Canada's Mark McMorris won the respective Best Action Sports Athlete prizes at the annual Excellence in Sports Performance Yearly (ESPY) awards.
The pair were handed their prizes at a glamorous ceremony at the Microsoft Theater in Los Angeles hosted by legendary National Football League player Peyton Manning.
The awards recognise individual and team athletic achievement and other sports-related performance during the calendar year.
Gasser finished top of both the International Ski Federation Snowboard Freestyle and Big Air World Cup standings.
The 25-year-old claimed her maiden global crown at the Freestyle Ski and Snowboard World Championships in Sierra Nevada after winning the women's big air competition.
She also claimed a gold medal in slopestyle at the Winter X Games.
"I can't believe that I won," she said.
"It was an honour for me to be nominated but now I'm even more happier to have been voted number one.
"I want to thank everyone who voted for me.
"It means a lot to win fan voting."
McMorris, winner of an Olympic bronze medal at Sochi 2014 in the men's slopestyle, had a successful campaign as he won crystal globes in the overall Freestyle World Cup standings and the big air competition.
His season had a bitter end, though, when an accident during a back-country snowboarding trip in Whistler in March left the 23-year-old with several injuries including a fractured jaw, ruptured spleen and collapsed left lung.
Canada Snowboard's executive director Patrick Jarvisclaimed the team are confident McMorris will be able to appear at next year's Winter Olympics in Pyeongchang.
