The Hawx Prime 85 W is a huge favourite with many skiers due to its smooth, progressive flex and precise feel. Sometimes softer flexing boots can be geared only towards comfort by having excess volume. Not in this case, the Prime 85 W has a user-friendly stiffness and a shell that is built for good skiing thanks to the Prolite design of lightness, power and sensitivity. Memory Fit allows the plastics to be custom moulded in-store for the best possible shape; a pre-shaped Memory Fit 3D Silver Liner fine-tunes the fit.Ability LevelOverviewFitMedium fit around the heel and ankle, medium to high instep, medum to wide across the forefoot.Shell PU Memory Fit shell and cuff, mouldable. The advanced heat fitting technology of Memory Fit creates a fully personalised shell and cuff in minutes. The key is Memolink, a special additive that improves the mouldability and stretch characteristics of the plastic. The boot shell is heated in an oven, then the skier\'s foot is placed inside the complete boot whilst it cools. With the foot\'s natural standing pressure, the forefoot of the boot can expand up to 3mm per side and the ankle area up to 5mm per side.Liner3D Silver W, mouldable. Thermoformable material is used in the heel and ankle areas. The liner is heated in an oven and is cooled to form to the shape of the skier\'s feet. 3D means pre-shaped heel and ankles areas for better foot hold and comfort.Key FeaturesProliteProlite is a way of building skis and boots that turns traditional thinking on its head. Instead of starting with a standard construction and cutting material away to save weight, Prolite does the opposite. It starts with the slimmest possible profile and then it builds up reinforcements in key areas where strength is needed.energy BackboneThe energy Backbone is a reinforced, asymmetric backbone that provides extra strength for powerful skiing plus enhanced lateral energy transmission for better edge grip.SpecificationCategory: AlpineFlex: 85Last Width: 100-106Custom Shell: YesCustom Liner: YesPower Strap: Velcro 35mmVolume: Medium Clips: 4 x 6000-Series Aluminium, MicroadjustableSole Unit: Alpine (Adult ISO 5355)Pin Inserts: NoHike Mode: NoWeight (g): 1680 (1/2 pair size 24.0)Binding Compatibility: Alpine, GripWalk, WTR, Multi Norm
