The Constrictor II BOA is a high performance, sporty winter boot that delivers maximum warmth and protection after skiing, around town - or when receiving a gold medal like Viking Test Pilot and alpine skier Kjetil Jansrud.
 
This sturdy, mid-high boot is made from a durable textile upper with nubuck reinforcements and a snow block cuff. It comes with a waterproof and breathable GORE-TEX® membrane and a high loft wool blend lining that delivers excellent insulation. The ingenious BOA® lacing system replaces laces with strong wires that are tightened with a wheel that can be released instantly by just pulling.
 
Vikings Nordic last provides a comfortable fit and the EVA midsole is shock absorbent and helps keep weight down. Vikings own Ultimate Grip Concept®, provides excellent traction on snow and slippery surfaces.
