Frenchwoman Charlotte Bankes and Christopher Robanske of Canada claimed victories in the last International Ski Federation (FIS) Snowboard World Cup snowboard cross event of the season, while Nelly Moenne Loccoz of France and Spain's Lucas Eguibar sealed maiden overall titles at La Molina.
Bankes took the women's honours in an exciting race which rounded off the season in fascinating style as she traded the lead with compatriot Moenne Loccoz, whose runner-up place handed her a first-ever crystal globe.
Four-time world champion Lindsey Jacobellis of United States was third.
"It was a very tight final with tough conditions," Bankes, a former junior world champion, said.
"It's been some great racing and I will try to continue on today's win next season."
The result gave Moenne Loccoz a final total of 2,400 points as she finished ahead of defending champion Dominique Maltais of Canada and Italy's Michela Moiolo, who both amassed 1,900 points.
"It was a pretty difficult race today because of the weather and the snow conditions but we had a lot of fun with the girls," the Frenchwoman said.
"I'm pretty happy to have won the globe today with only second rank finishes."
In the men's competition, Robanske proved too strong for the rest of the field in what was a closely-contested final with 2014 Olympic bronze medallist Alex Deibold of America, while Australian Alex Pullin came through to take third.
Despite only finishing in ninth place, Eguibar did enough to secure his first crystal globe as he ended the season on a total of 2,090 points, 390 ahead of nearest challenger Pullin, who looked on course to take the overall crown before he collided with Italy's Luca Matteotti.
"I'm so happy to win the globe although the season was so short," the victorious Spaniard said.
"I want to dedicate the title to my family and my team.
"I made a good job in Veysonnaz but was very lucky today."
The meeting in the Spanish resort rounds off a short season, which comprised of just three snowboard cross competitions.
