Last: 100 mm – This mid-wide last securely envelopes the anatomical contours of the foot for maximum foot retention with enhanced sensitivity and responsiveness.

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.

Cuff Hyperband – This wide profile shin pad offers extreme versatility, low friction and fit & function.

Low Contour Cuff – 0.5 - 1.5 cm lower cuff and rear spoiler for women's specific geometry. Fits a wide range of women's lower leg shapes.

Flex: 110 – Powerful flex for advanced to expert female skiers.

Kinetic Response Tongue – Highly resilient polyamide flex ribbed tongue stays in permanent contact with the leg for improved responsiveness and control. Interchangeable flex stiffness.

I.F. (Instant Fit) Air Liner – Dalbello's I.F. Liners are designed with special progressive density thermo materials integrated with a traditional "tongue" liner construction. While they are pre-molded and fully skiable out of the box, I.F. liners are easily and quickly custom moldable as well.

Cabrio Design Architecture – Dalbello's 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 flex. 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.

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

New Hike & Ride Mechanism – Solid and sturdy cuff lock/unlock mechanism releases the upper cuff from the lower shell permitting free hinging rotation for an extended range of motion for hiking or climbing. Engineered for maximum performance and power transfer when engaged in “lock” position.

Cuff Range Movement – Thanks to its construction, the Lupo offers one of the highest range of motions available in the market: 67° (40° Forward Lean, 27° Backward Lean).

Removable Tongue – Taken away easily with only one hand, the removed tongue offers endless forward lean movement while hiking and great skiing performance for downhilling due to it's 130 flex.

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

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.

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

Screwed Rivets – Dalbello uses high quality screwed rivets (as opposed to permanent “crimped” rivets) to allow for easier bootfitter access and repair.

Grip Walk Outsoles – 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.

Xtra-Grip™ / Quadralock Stability Pylons – Replaceable high traction composite polyurethane toes & heels. Lightweight and durable textured design for improved traction on all surfaces + anti slip functionality. The high durometer, reinforced polyurethane Quadralock Stability Pylons provide solid boot to binding interface at 4 points, minimizing sole compression and flex.

Alloy Tech Inserts – For fitting compatibility with select Alpine Touring Bindings requiring special metal inserts at the boot toe and heel interface, Lupo & Sherpa T.I. tech inserts are cast as a solid pieces of steel-alloy with uniform dimensional and structural characteristics seamlessly integrated into the boot during manufacturing.

Interchangeable Alpine Soles [Sold Separately] – Due to the inclusion of metal tech inserts in the Lupo bootsole lugs, aftermarkets replacement alpine sole plates are NOT CERTIFIED to conform to alpine ski boot norm (ISO 5355) sole standard.
