• Asym 3F Design - A unique asymmetric boot design co-developed with BOA® that generates optimal support and flex while reducing foot fatigue and cramps.
• Exo Spine - An external backstay that supports the whole boot and transfers energy instantly from heel to toe. 
• Armor Tech - This bombproof TPU strip wraps around the front of the boot to shield if from abrasions and prevents the boot from packing out too much, prolonging its life.
• 3D Liner Support - 3D molded material and J-bars around the ankle means minimal movement and maximum control.
• 3D Molded Toebox - Eliminates extra layers and seams around the forefoot, improving water resistance and durability
• 3D Molded Tongue - An asymmetric 3D Molded Tongue is curved more sharply towards the medial side to match the natural ridgeline of your forefoot, alleviating pressure points and providing more comfort and support.
• KPU - A unique injected polyurethane that's 100% waterproof, allowing seamless uppers with high abrasion resistance and consistent flex.
• Articulating Cuff - The upper shell overlaps the lower part and moves independently. This creates a super smooth ride and eliminates any buckling or pressure points when the boot is flexed.
