Last: 102 mm – This versatile, wider forefoot last fits a wide range of feet comfortably, with a closer fitting ankle and heel pocket to prevent travel inside the boot.

Contour 4 Shell Fit – Contour 4 Technology is a revolutionary technological advance in performance ski boot fitting. The anatomical contours of the inside sidewalls of the boot-shell, as well as the innerboot lasts, are precisely “mapped” to the shape of the typical high performance skier’s foot. A little extra “space” is molded into the inside of the boot shell at 4 critical fit points: ankle, heel, 5th metatarsal, and navicular.

Split Fit Tongue – Dalbello’s Split-Fit Tongue has a unique fore-aft sliding design that allows the tongue to accommodate a taller instep comfortably. The sliding function also allows for extremely easy entry and exit.

Cuff Volume Expansion Adjustment – Circumference of rear cuff spoiler on Kyra may be increased to accommodate varying lower leg volumes and/or shorter leg lengths.

Flex: 75 – A softer flex for progressing beginner to intermediate skiers.

Adjustable Flex – With the turn of an allen key, a function on the back of the cuff allows you to adjust the boot's flex by approximately ten flex points from 75 ("hard") to 65 ("soft").

Supercomfort Liner – With Comfort Density foam and an Adaptive Comfort Toebox, the Supercomfort liner is designed to bring you just that - superior amounts of comfort. The liner is also compatible with most boot heating systems.

Cabrio Design Architecture – Cabrio Design Architecture - Dalbello’s critically acclaimed, 3 Piece Cabrio Design architecture has been the cornerstone of their performance, all mountain and freestyle models for more than a decade. This unique construction combines a 3 piece construction assembly - shell/cuff/tongue – that comfortably secures the foot and lower leg while optimizing smooth and progressive flexibility. Dalbello’s Cabrio models provide the ultimate in responsive performance to ski your best. Cabrio Design permits the use of stiffer and more rigid plastics in the lower shell. This strengthens the support around the foot and lower leg providing quick response and precise transfer of power to the ski edges. This design also prevents the lower shell from distorting and bulging as the boot flexes, making the boot more smooth and stable at high speeds and on irregular terrain.
