K2 has just unveiled a new line of ski boots that that’s scheduled to hit shelves next fall. There are eight models in total that include three men’s and three women’s all-mountain models as well as two freeride models.

The SpYne is the men’s all mountain boot and is offered at three different flex ratings (130, 110 and 90) as well as three different lasts (97mm, 100mm and 102mm). The boot is a traditional 4-buckle overlap shell whose name is derived from a “Y” shaped spine on the back of the boot that is meant to provide more efficient flexing and increased lateral stiffness. The combination of three different lasts with a punched out instep and heat-moldable Intuition liners is being dubbed “K2 Fit Logix.”

The Women’s all-mountain boot is called the SpYre and differs in two areas from the SpYne. The cuff height is 15-percent lower to accommodate the female leg anatomy and the flex offerings are 110, 100 and 80.

On the freeride side of things, the Pinnacle 130 and Pinnacle 110 are the two new offerings. They’re touring-enabled boots that K2 says will “maximize uphill capabilities without compromising performance.” The Synchro Interlock hike/ski mechanism is said to provide “impressive fore and aft range of motion” and the soles have tech fittings embedded, making them compatible with all modern DIN- alpine and Tech binding systems. Three buckles are topped off with a buckle/strap on top that K2 calls the PowerBuckle and inside is a LuxFit Intuition liner.

On paper, the boots look like they could be serious contenders in the aggressive all-mountain and freeride categories. The images also look good but we look forward to getting them in the field and putting them to the test. Stay tuned.
