• The Altai's BOA® dials have been upgraded to the latest H5 Coiler™ tech, enabling precise micro-adjustment in both directions so you can fine-tune the fit on the fly.
• The new Ascent 2.0 outsole delivers awesome cushioning and traction, with improved Supermatic® compatibility and enhanced grip when hiking over ice and rock.
• The Altai's 3D Pro insole and heat-moldable Silver Liner feel awesome straight out of the box, with the option to customize the fit even further.
• Dual BOA®
  • Dual BOA® technology provides quick, precise lace adjustments via two independent dials. Each controls a distinct boot zone, delivering a custom fit in seconds.
• External Heel Lock
  • Our External Heel Lock works in tandem with the BOA® dial on the tongue, tightening built-in wings on either side of the ankle to minimize heel lift.
• Ascent 2.0
  • The Ascent 2.0 builds on the original version with an improved Transition Zone and stiffer, more durable heel rubber for enhanced compatibility with speed entry bindings. Upgraded rubber traction at the forefoot and heel delivers superior grip.
• Silver
  • The Silver liner can be heat molded for a custom fit and features a Custom Flex Zone at the toes, 8mm PE foam, and added PU support. A separate cuff connected to the shell ensures easy entry, while Velcro patches on the tongue secure the fit.
• Shell Harness
  • Pull the inner laces to tighten a shell-mounted harness. Velcro secures the tongue.
• BOA®
  • The industry standard in speed lacing systems. Micro-adjustable for a precise fit and engineered to perform in the toughest conditions.
• Moldable Liner
  • Made from advanced memory foam, our moldable liners adapt to your foot shape over time or can be heated in store for an instant, personalized fit. Experience zero pressure points and maximum comfort.
• Asym 3F
  • A unique asymmetrical design co-developed with BOA® for optimal support and flex. The tongue's lace guides are positioned over flatter forefoot areas for even closure and reduced pressure points. Enhanced medial arch support fights foot fatigue.
• Articulating Flex Zone
  • The upper boot cuff is asymmetrically connected to the lower boot, allowing the ankle to flex naturally and providing great support without shell distortion.
• 3D Molded Toebox
  • Our 3D Toebox eliminates extra layers and seams around the forefoot, improving water resistance and durablility. The streamlined design also makes it easier to slide your boot in and out of the binding.
• 3D Molded Tongue
  • Our asymmetric 3D Molded Tongue features a sharper curve on the medial side to match your natural forefoot shape. This design eliminates pressure points and delivers more balanced comfort and support than a traditional straight tongue.
