What are the main differences in the different models of the Apex ski boots?


For the 2017/2018 season, we have four different Apex models. They are classified as the XP series, and the HP series. They all have the exclusive Open-Chassis boot system with a modular chassis and a walkable boot. And this year, all the models have a 3 buckle open chassis with an open toe architecture, making them dramatically shorter and lighter than last year’s M-series.

They all have a multi-density EVA foam, heat-moldable liner and a speed lace system for added support.
