K2 Snowboard boots are engineered to keep you on the slopes for a longer time and with more comfort. Most K2 Snowboard boots comes with intuition liners, a patented foam developed specifically to be lightweight, moldable, flexible and durable for snowboarders at all skill levels. The intuition liners are designed to be custom molded to your foot shape to give you the best personalized fit you can get. Another feature worth mentioning is the Endo construction that is featured on the higher end K2 Snowboard Boots. The Endo construction focuses boot structure and flex into a single engineered part. The result is a boot that flexes and returns without breaking down, so you get consistent flex and quicker feel without more energy and less fatigue. The full list of features is long so we recommend looking at individual boots to get the full list of features.
