The K2 Thraxis Men's Snowboard Boots are for hardcore, aggressive riders who want stiff boots. And by stiff, we mean a 10 out of 10 rating on the stiffness scale, so these boots are not for the weak. The Thraxis boots are completely dialed for precision hard charging on piste or off, front side, back side and everything else in between. It's got a full BOA lacing system both inside the liner and outside the boot for a super adjustable and snug fit each and every time. Supported by an Intuition Pro Foam 3D liner with Spaceheater technology, this is a liner designed for comfort and warmth, from start to finish. It features reflective heat blanket panels that work to trap heat in and keep cold out. These reflective heat blankets work alongside heat moldable Intuition foam, internal J-Bars, and 3D molded dual-density EVA insoles to keep your foot comfortable and warm all day long. A Vibram V5 outer sole features full EcoStep rubber with Harshmellow pads under the toe and heel of the boot to reduce noise and chatter when the terrain gets rough. This is a mean boot packed with name brand tech and premium construction. The K2 Thraxis Men's Snowboard Boots are the true cream of the crop boot that will answer the call for all bad ass riders.
