Feasey's 57 FIS point result is a career best and will improve his international ranking.
With a combined time of 1:45.73, Feasey edged out Liechtenstein's top junior Nicola Kindle who placed second with a time of 1:45.90. British Europa Cup Team member Aaron Tipping took third.
Feasey, who trains with the Cardrona High performance Centre in NZ, is working with coach Adi Bernasconi at the Worldskiconnection base in Frutigen, Switzerland.
Bernasconi reports he is pleased with how well Feasey is skiing and says this result bodes well for the performance we can expect from Feasey for the rest of his northern hemisphere season.
