The Altai is the centerpiece of our women's boot collection, offering premium features and support at an exceptional price. It’s built around a dedicated female last, with dual H5 BOA® dials to allow you to tighten the upper and lower sections independently. The responsive, mid-stiff flex is great for digging trenches in the piste or floating through forests with pinpoint accuracy. If you love the art of the turn, you’ll love this boot.
Key Features:
- 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.

Extras:
- 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 balanced 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 minimizes extra layers and seams around the forefoot, improving water resistance and durability. 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 minimizes pressure points and delivers more balanced comfort and support than a traditional straight tongue.

The next evolution in BOA® technology features micro-adjustability – simply turn the dial in reverse to gradually release tension and fine-tune your fit. Lower profile design gives the boot a clean look and reduces snag risk.
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.
