Bootfitter's Comments – Mid-wide forefoot with an average midfoot and instep height. Aggressive heel pocket fit.

Reverse Engineering – The Khion fit, with a larger, pre-punched metatarsal area and more relaxed instep height than previous Dynafit freetouring models, was developed using a reverse engineering development process.

Very Stiff Flex

Side Bumper – These cushioned stops between the 2nd and 3rd buckles allow super progressive turn response.

Custom Ready Liner with Ultralon™ Heat Moldable Foam – Dynafit's Custom Ready Liner is a comfy, heat moldable liner that stands up to the repeated abuse of removing it and sticking it back in the shell.

Mapping Construction – Careful placement of thinner but slightly denser liner materials, developed in conjunction with Dynafit's stable of backcountry athletes, provides excellent skiing response with superb heel hold.

Quick Lacing Closure System

Power Drive Tongue – This asymmetrical tongue design features a central anchor rib to increase contact area and reduce play, resulting in improved power and comfort while skiing.

Lower Shell / Cuff – Pebax / Carbon Fiber

Magnesium Spoiler – A super rigid spoiler that promotes outstanding ski performance and lowers the overall boot weight.

Exoskeleton – This external shell framework provides lateral and forward rigidity to the boot and allows softer materials to be used in areas critical to walking and skinning comfort.

Forward Lean – 16˚

Range of Motion – 90˚

Precision Lock System – A patented Dynafit system that provides the most positive connection in the touring world, for precise and immediate skiing response. In "ski" mode, the shell, cuff and super rigid magnesium spoiler are locked as a single unit; when in "tour" mode the Precision Lock System allows an amazing 90˚ range of cuff motion.

Magnetic Buckle Catchers – Catch plates on the boot shell are magnetized to hold buckles in place while adjustments are made and keep unfastened buckles in place while touring.

One Touch Buckles – This patented system allows you to open the buckle completely with a single motion.

No Power Strap – One less thing to deal with; this boot is plenty stiff without one.

Formula Pomoca® Sole – Pomoca® uses a highly abrasion and cut resistant compound, combined with a tread pattern that enhances walking and provides immediate lateral response when skiing.

Snow Dynamics Concept – For the first time, a boot has been engineered to excel in deeper snow with minimal snow resistance. The compact profile and streamlined buckle configuration reduce drag, protect components from damage by ice and rock, and help ensure efficient travel while booting.

Quick Step-In Insert – Genuine Dynafit Quick Step-In inserts have a subtle ridge to aid in positioning the toe of the boot in the binding.

Compatible with tech and ISO 13992 alpine touring bindings
