Guided by this belief, we set out to develop an entirely new sole for our Unlimited boots–a sole that was as versatile as it was durable. It had to offer exceptional grip to ensure it could withstand hiking in the most treacherous terrain–be that a rocky summit, high-stakes glacial traverse, or a parking lot coated in ice. Yet it also had to interface perfectly with countless binding systems while maximizing safety and control. This led to the creation of a sole that provides the legendary traction and performance of the Michelin Gripwalk system while also featuring DYN inserts. This sole is compatible with both ISO Gripwalk and alpine touring standards. And thanks to its screw-on design, the sole can readily be replaced to maximize the longevity of the boot. No matter how you define adventure–or where you pursue it–you can depend on Nordica's Unlimited soles. TRI FORCE CUFF CONSTRUCTION By strategically positioning three different densities of materials, Nordica's Tri Force Cuff Construction boosts the fit and performance of a boot while minimizing weight. CHANGE/SWITCH WITH CONFIDENCE Nordica's ski-walk mechanism maximizes performance and comfort whether skiing, hiking, or skinning. It reduces weight while pairing exceptional control and response with a tremendous range of motion. INFRARED TECHNOLOGY Infrared Technology has been developed by Nordica with the aim of customizing the boots in the most sensitive point for the skiers. Once you identify the pressure points, you just need to heat the area through the infrared lamp. In a second step, apply the suction cup to neutralize the pressure in few minutes. Lastly, remove the cup and replace the liner: it's time to jump into the boots and enjoy the ride. 3D CORK FIT PRIMALOFT LIGHT LINER Designed to maximize performance and comfort while also reducing weight, Nordica's 3D Cork Fit PrimaLoft Light Liner pairs a 3-D custom cork liner with a composite collar that boosts control and response. ADJUSTABLE LINER TONGUE Adjustable tongue is a velcro flap, positioned at the end of the tongue liner. This simple system enables a quick customization for the best set-up and power transmission. ISOTHERM Isotherm is one of the many materials we used to build our liner, well-known to keep the warmth and wicks away moisture.
