Dynafit M Blacklight Alpine Touring Boot
The men's Blacklight weighs a claimed 1,140 g per boot and combines a 70° cuff rotation, 101 mm last, carbon-reinforced Grilamid shell, and the Hoji Lock system. It targets long, technical ski mountaineering and fast backcountry touring where uphill efficiency matters but a race boot would sacrifice too much downhill support.

Bootfitter's Advice
The 101 mm last is moderately accommodating, but the Blacklight fits like a performance boot because the liner is thin and the shell is structured. The lower shell will likely feel wrap-tight, especially before heat molding or breaking in the liner. It suits medium-volume feet better than very wide or high-instep feet.
The heel pocket is secure for most skiers but not race-boot tight. Narrow heels may benefit from liner padding. Extensive shell work is less desirable given the carbon-reinforced construction, so starting with the correct shell shape is important.

Our Verdict
Premium Ski Touring Binding for Backcountry Adventures
The Dynafit Blacklight Pro Binding is a lightweight, adjustable binding that takes speed touring to the next level. The robust aluminum toe piece and laminated carbon heel piece offer reliable stability, control, and safety without extra grams, keeping you light and spry for approaches and technical descents.
Easy Entry System for Challenging Conditions
Need to step in on an icy slope? Fear not, the Blacklight Pro features Dynafit's Easy Entry System to get your boot in the binding faster and, well, easier. An extended cam provides ergonomic opening and locking that you can manipulate with your ski poles, while the binding's length adjustment keeps release values consistent when the snow gets chunky and rough. Two walk modes let you maintain efficient stride whether you're skinning across mellow approaches or powering up steep sections.
Fully Adjustable Performance & Lightweight Design
With fully adjustable release values from Z 6–12 and a 20 mm adjustment range, the Blacklight Pro gives you options for fine tuning. It comes without stoppers to maximize weight savings, but includes the option to retrofit brakes when needed (or choose the Blacklight Pro+ version with brakes included). And with the Quick-In Crampon Slot, you'll be ready to "speedup anywhere – ski anything."
