Be One with your boots, Be One with your goal.Features:Fit:- The Fit of the boot (or last) is the width of the foot measured at the 5th metatarsal (widest part of the forefoot). It determines the level of control and precision of the skier. For a good ratio between comfort and control, choose a boot that matches the overall volume and length of your foot. Fit between 92-95 mm: Narrow, Fit between 97-99 mm: Medium, Fit between 100-102 mm: ComfortFlex:- The flex of a boot indicates the level of support that boot will deliver. The greater (stiffer) the flex index, the more rigid and reactive the boot will be. The lesser (softer) the flex index, the more tolerant and comfortable.Level:- Choose the boots which offers the best ratio between comfort and performance. For a beginner skier, we recommend a flexible flex (90).Specifications:- Weight: 2175gShell:- Shell Material: Polyether Dual Core- Shell Technology: Dual Core- Shell Bootboard: Hard Polyurethane FoamCuff:- Cuff Material: Polyether Dual CoreLiner:- Liner Tongue: Power Wedge Tongue- Liner Power Strap: 50mm Cam Lock- Liner Type: Dual 3d Full LinerBuckles:- Buckles Technology: Alu Race Micro, Shell Articulting, ScrewedSoles:- Soles Specifications: Solid Sole- Soles Features: Gripwalk CompatibleOther:- Canting: Dual Screw Canting- Spoiler: Removable SpoilerTechnology:Dual Core:- As You Drive And Flex Into Your Boots, Dual Core Actively Compresses And Expands - Harnessing Potential Energy To Deliver Explosive Power, Snap, And Rebound.
