Ingeniously designed with K2's Endo 2. 0 construction, the Men's Maysis Boa Snowboard Boot retains a smooth, consistent flex throughout long seasons of lapping the park, shredding powder, and seeking out lines. This construction process employs a durable TPU heel counter that resists folding up like a taco after 100-plus days on the mountain, maintaining its medium flex pattern without succumbing to premature wear and tear. One of the most popular Double Boa boots on the market, the Maysis Boot features two separate Boa dials that independently tighten the outer shell and liner for a dialed, ultra-supportive fit. The H3 Boa Coiler dial located on the tongue controls the outer shell's tightness, quickly tightening the entire boot with a few clicks. On the side of the boot, the Boa Conda dial tightens up the boot's liner, eliminating excess slop and heel lift as you ride without unlacing the boot just to reach its liner harness. Seeing you'll be wearing the Maysis Boot for hours on the mountain, it's hooked up with an Intuition Control Foam 3D foam liner for a supportive, foot-wrapping fit. This heat-moldable liner is a bit softer than what you'd find in K2's top-end freeride boots, yet it's designed to resist packing out throughout the season. This means you'll reap the benefits of a smooth-flexing boot that's ideal for riding everything on the mountain with its mid-level flex, yet one that doesn't become a sloppy noodle after long days of riding.
