Zavarzina's best season in terms of World Cup results came in the &lt;a href="2016%E2%80%9317%20FIS%20Snowboard%20World%20Cup"&gt;2016/17 season&lt;/a&gt;. She won two World Cup parallel giant slalom races in Bansko and Bokwang, the latter was also the test event for the upcoming Winter Olympic Games, and grabbed one more podium spot in the same discipline with a third place-finish in the season-opener in Carezza. Although her podiums came in parallel giant slalom, she won a bronze medal in the parallel slalom at the 2017 World Championships in Sierra Nevada which was her first senior medal in this discipline. With this medal, Zavarzina completed the full set of medals (gold, silver and bronze) from the World Championships. In the parallel giant slalom event, Zavarzina set the second fastest time in the qualification round but lost to her teammate Yekaterina Tudegesheva in the quarter finals. At the end of the season, Zavarzina clinched the parallel giant slalom crystal globe for the first time in her career. She was also leading the parallel overall World Cup standings by a slim margin over Ester Ledecká prior to the season finale in Winterberg, but Ledecká finished as the runner-up in the last race of the season while Zavarzina was seventh and claimed the overall crystal globe ahead of Zavarzina.
