We want it all, and the K2 Anthem 105 BOA Boot delivers. Equipped with the micro-adjustable BOA Fit System, this boot gives our forefoot an even hug-no pressure points-while the fully heat moldable construction lets us customize the shell and liner to our feet, resulting in the best fit out there. K2 didn't stop at comfort: they gave the Anthem 105 a stiff flex and a Powerfuse Spyne to ensure we have lateral stiffness for carving and responsiveness through the trees.
