K2 has expanded its offering this season by offering the Spyne in three different last widths. This particular version of the Spyne sports a medium-wide last of 100mm.The Spyne incorporates much of the same technologies you'd expect to find on a high-end boot: four micro-adjustable buckles, a cinchable power strap, adjustable canting, and an adjustable forward lean, but where the Spyne really differs is with what K2 calls its E3 design philosophy. The E3 design philosophy combines a carbon-infused spine that runs down the back of the cuff to the heel of the shell to add an extra bit of rigidity to the bootthe carbon spine allows for less material to be used in the shell and cuff, resulting in a lighter boot that's also easier to work with in the shop. In addition to the Powerfuse Spyne, K2 also developed a connection between the shell and cuff by eliminating the use of rivets. The interlocking connection not only allows the boot to flex forward more naturally, but it puts less stress on the rest of the boot and offers a smoother ride as a result. Adjustable canting and forward lean. The item "Men's Downhill Ski Boots 26.5 By K2 Model Spyne 130 Color Green" is in sale since Tuesday, October 2, 2018.
