The K2 Thraxis Snowboard Boots are designed for big lines and bigger ambitions. The most aggressive of K2’s freeride boots combines a very stiff flex with all the top shelf features you expect, like Intuition SpaceHeater liners and Boa Conda closures for a quick and supportive fit every time out. The Thraxis gives as good as it gets, and remains the standard for power riding both in and out of bounds.
