Shiffrin opened the 2015 season in October 2014 in Sölden with her first World Cup win in giant slalom. She had some trouble with slalom at first and ended up outside the podium in the first three World Cup slalom races, but emerged victorious in the races at Kühtai, Zagreb, Maribor, Åre and Méribel. She ended up winning the slalom world cup title once again. Shiffrin also won the World Championship in slalom held in Beaver Creek next to her home city of Vail, Colorado, USA.
