The Swiss finished sixth as Italy’s Dominik Paris – his chief rival – took victory. Norway’s Kjetil Jansrud and Austria’s Otmar Striedinger placed second and third respectively.
Feuz only triumphed in one race this season, but six podium finishes in eight races saw him pip four-time winner Paris to glory by 20 points in the final standings.

"It’s incredible for me to have two globes now. Dominik is in a super form and I am really proud to have won it," said Feuz.

An 11th-placed finish was enough for Nicole Schmidhofer to win Austria’s first downhill title since Renate Goetschl in 2007.
Schmidhofer’s place at the summit could have been threatened by Ramona Siebenhofer, but her compatriot – who knew only victory would keep her hopes alive – botched a jump and finished outside the points.
"It hasn’t sunk in yet," Schmidhofer said. "But to be named in one sentence with Goetschl is something really special. She won in 2007 when I won the junior world title."
The race was won by another Austrian, Mirjam Puchner. Germany's Viktoria Rebensburg was second ahead of Switzerland's Corinne Suter in third.

Schmidhofer is also targeting the Super-G title, although she needs a big – and unlikely – slip-up from Mikaela Shiffrin to take glory.
