Last: 103 mm – Wide fitting last combines an expanded volume forefoot and toe box area with a closer fitting rearfoot and ankle area. Comfortably accommodates a wide range of foot shapes with max foothold and exceptional comfort.

Contour 4 – 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. Contour 4 represents the first level of Dalbello's My Fit System.

My Fit System – The Dalbello legendary fit got an upgrade in more than 60% of the boot range thanks to the My Fit System. Liner and shell can now be thermo customized in addition to the pre-molded Contour 4 shell which is included in every My Fit boot.

Flex: 110 – A medium-stiff adjustable, all-mountain flex.

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 from 110 down to 100.

IF Performer – Performance/comfort fit with medium density ULTEVA heat moldable (4 min) foam. Adaptive Comfort toebox; Heat system ready

3 Piece Architecture – Dalbello’s critically acclaimed, 3 Piece Cabrio Design architecture has been the cornerstone of their top 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. Accept no imitations.

Total Landing Gear Cuff – Softer PU material spans a “V” cut in the upper cuff providing a slight amount of stretch to absorb landings without compromising performance or control.

Total Landing Gear Tongue – Revolutionary XRD material is strategically placed in the shin area of the tongue to absorb impact for less fatigue and eliminate shin bang.

Shell / Cuff / Tongue – Bi-Injected PE (Polyether) / PU (Polyurethane) / PU

Dynamically Balanced Stance – Foot angle, cant angle, and cuff inclination engineered into the shell and cuff positions skiers in a balanced and centered stance for optimum dynamic performance.

Low Cuff Hinge Point – High leverage cuff assembly with hinge points mounted approximately 10 cm lower than standard construction boot designs. The low hinging cuff permits the boot cuff to more easily follow the natural movement of the skier’s legs because it has a longer range of forward and rearward hinging motion.

Adjustable Cuff Alignment – Permits skiers to align the lateral inclination of the upper cuff to the skier’s leg. Outside hinge cuff alignment using 5 mm hex tool, rotate the mechanism clockwise, or counterclockwise, to align boot cuff to desired position.

Micro-Adjustable Aluminum Buckles – A simple turn of a buckle! Micrometer buckles are easy to use for easy fit customization.

Inverted Forefoot Buckle – Forefoot closure buckle above the instep is inverted and designed to close on the top of a boot shell, not the side. The top closure positioning prevents buckle breakage and bending during rail slides, grinds, falls, and transitions.

Dynalink Rearfoot Retention – Dynalink is an independently functioning heel/instep closure band assembly that secures the skiers foot in the middle and rearfoot sections of the ski boot.

Twinstep Closure – Two position buckle closure allows for optimized pressure distribution over the instep.

Orthofit Performance Insole

Grip Walk – The new boot sole-binding system for increased walking comfort and improved natural gait thanks to a rockered rubber sole. Deep lugs are slip-resistant to provide better traction. Compatible with all "Grip Walk Ready" alpine bindings as well as tech bindings.

Dura-Grip™ – Replaceable, durable high-durometer polyurethane toes & heels for extended boot sole wear.

Total Landing Gear Heel – XRD material absorbs shocks and vibrations for smoother skiing and less fatigue.
