Features

Phoenix last
The Phoenix last, based on the Dragon, offers more volume in the forefoot, instep and lower leg while maintaining a secure heel hold in a performance fit.

Liner & Tongue Construction
Phoenix liners offer the latest in construction and materials to provide superior heel hold and foot envelopment with unequaled comfort. A new, higher tongue with a ribbed design offers better wrap and a more consistent flex.

Velcro Spoiler
A velcro rear spoiler allows you to easily adjust the spoiler for personalization. It can be moved to different positions, or removed altogether.

Cuff Alignment
The Phoenix cuff alignment system is easy to use and effective. It aligns the cuff to follow the shape of the lower leg increasing comfort and enhancing performance.

AVS with Grip Sole
Bi-injected A.V.S. (Anti-Vibration System) design provides maximum shock absorption while also offering a non-slip function to the sole of the boot.

Carbon Steel Buckles / Toe Buckle
Carbon Steel buckles are extremely strong and thin offering a low profile for reduced breakage and better aerodynamics. Unique 1st buckle positioning offers better wrap and closure around the forefoot, while lifting the buckle away from the snow for less interference.

H.V.L - High Volume Last
The H.V.L. - High Volume Last found in the Phoenix 110 H.V.L is designed for individuals with E - EEE widths. The last changes have been made internally ensuring correct closure and wrap of the shell.

3 Position Catches
The cuff catches can be easily moved to fit varying leg shapes. The positioning catches have a range of 44mm: 22mm forward and 22mm back.
    
    
Technology

3 Density Technology
3 Density Technology is a combination of two different (soft & hard) plastics that create 3 different zones of hardness within the shell. In the Dragon Series, 3D is designed for power and strength by utilizing more hard than soft materials. An asymmetric design delivers more power to the edge. In Phoenix it addresses both power and entry & exit using more soft material than the Dragon. Within Mega, the primary emphasis is to make entry & exit easy by using the most soft material of the three variations.

Air Shell
Air Shell is a new, custom fit technology. Air shell consists of two independent and inflatable air bladders to create two fit zones, a forefoot zone and a heel zone. Both zones trap air where there are voids between the foot and shell to customize the fit and provide greater insulation and warmth. The two zones are inflated or deflated by using the pumps on the rear spoiler of the boots. The amount of air pumped into the bladders is controlled by you: to fit your foot shape and suit your personal preferences. No tools are required. It is instantaneous and can be done an unlimited amount of times offering a true, custom and variable fit.

Delta Force System
The Delta Force system is a flex adjustment system that utilizes three components to effectively allow the skier to adjust the power and rebound flex of the boot; the device itself, the hinge point and the 3D design. The Hinge Point of the boot has been moved forward and higher to be able to maximize the efficiency of the device. The 3D design uses a lower, ribbed rear spine that works with the hinge point and device for a more progressive flex, better rebound and direct power transmission. The device is a simple lever with an internal barrel. A dual density elastomer on the barrel is not affected by temperature. Flick the lever up to increase the stiffness of the boot, push the lever down to increase the flex of the boot.
