Liner Technology Liner Technology All our liners feature an Asymmetric Liner Construction (ASY) with an asymmetric tongue, toe box, collar shape and high-quality lining materials. It’s the most anatomical construction on the market, and the best for supporting your feet while skiing. In addition, this year we’ve created a Memory Fit 3D liner for our Hawx Ultra and Hawx Prime boots. This liner includes pre-shaped heel and ankle areas for an even better first fit. PLATINUM – GOLD – SILVER – BRONZE Our new Memory Fit 3D liner comes in Platinum, Gold and Silver grades. Our standard liner also comes in a Bronze grade. You’ll see these labels written on the tongue. As our liners go up from Bronze to Platinum they provide the firmer fit better skiers need. They also become longer lasting, warmer and more personalizable. FIRMER FIT The number one thing for first timers and intermediate skiers is to have boots that fit comfortably. As skiers get better, that fit can get firmer and more responsive. Our liners support that progression, with firmer foam and higher-performance liner textiles as our boots go up in flex numbers. LONGER LASTING The pre-shaped heel and ankle areas in our new Memory Fit 3D liner mean the liner maintains its great fit longer. And to make sure the fit of our standard liners lasts for a long time as well we add Dynashape foam: Silver has Dynashape on the ankles, Gold on the ankles and sides, and Platinum on ankles, sides and tongue. WARMER From Silver upwards many of our liners feature 3MTM ThinsulateTM, the world’s best-known insulation. This means you get ThinsulateTM on Hawx Ultra, Hawx Prime, Hawx Magna, Waymaker and Live Fit. We’ve also added it to all our Kids boots, as little feet get colder quicker. MORE PERSONALIZABLE All liners have Memory Zones that are heat moldable for a personalized fit. These zones are on the ankle (1), side (2) and tongue (3) – with the zones corresponding to the liner level. 3M™ THINSULATE™ INSULATION We’re working in partnership with 3M to create the warmest ski boots ever made with 3MTM ThinsulateTM Insulation. It works like this: the more air a material traps in a given space the greater its insulating value. The microfibers in 3MTM ThinsulateTM Insulation are far finer than any other fibers, which means they trap more insulating air in less space, even when wet. This keeps feet warm and responsive even in extremely cold and damp conditions. DYNASHAPE Dynashape is a revolutionary foam that not only instantly adapts to the shape of the foot but it also provides a longer lasting fit at the same time. MEMORY FIT 3D LINER Memory Fit 3D is our new liner featuring pre-shaped thermoformable heel and ankle areas, which creates a snug anatomical fit around the heel and ankle for a better foot hold. So there are no pressure points when you put the boot on for the first time. Then for continuous comfort we’ve given the liner a 1-piece toe box that precisely follows the shape of the shell and surrounds the foot with comfortable foam. Also included are special Sidas footbeds that have the best blend of initial cushioning and proper support. And finally it’s 100% Memory Fit compatible. SHELL TECHNOLOGY PROGRESSIVE SHELL Hawx Ultra features our Progressive Shell, a revolutionary construction with optimized wall thicknesses. The shell walls are thicker in key zones where they need to be strong, then slim everywhere else. This makes the boot 25% lighter, and yet more stable, than other constructions. The best combination of snow-feel and power ever felt in an all-mountain boot. ENERGY BACKBONE The Energy Backbone is a reinforced, asymmetric backbone in our new Hawx Ultra, providing extra strength for powerful skiing plus enhanced lateral energy transmission for better edge grip.
