The Lien AT is built upon a Tunable Tripod chassis, which places three urethane pods directly beneath the baseplate for energy transmission and natural flex underfoot. The urethane pods transmit rider energy directly to your board while allowing it to flex naturally, as the pods are the only points of contact, compared to a traditional baseplate that sits flush against your board and feels dead underfoot. Best of all, K2 includes three different pod durometers (i.e. hardness levels), giving you the ability to customize its feel to your exact preferences. Use the softer pods for maximum shock absorption or place the hard pods underneath for greater energy transmission. Either way, its flex and feel is totally up to you, which is what K2 intended with this customizable chassis.
Never content resting on its previous success, K2 redesigned the highback to be lighter while maintaining responsive support when you're leaning into deep heelside carves. The AT Opti highback features an Airlock Gap Eraser that closes the gap between boot and binding for a seamless fit. Looking to the straps, the Precision ankle strap provides a locked-in, supportive feel with its 3D-molded structure, paired with the Perfect Fit 2.0 toe strap for a boot-wrapping fit without pinching or collapsing the toe box. As you'd expect from K2, all adjustments are tool-less, so you'll never be stuck atop the mountain without the ability to tighten the binding or fine-tune its fit.
