What Our Gearhead® Experts Are Saying: "At under 1,000 grams, the Blacklight boot flies on the skintrack but still holds its own on the descent. The carbon cuff and Twistfit system give it surprising power and control for how light it is. It's my go-to for long alpine missions where weight and reliability both matter." When the route is steep, technical, and remote, we need a boot we can trust with every step—and the Dynafit Blacklight Boot answers that call. Weighing just 990 grams, this ultralight touring machine maximizes uphill speed and efficiency with 60 degrees of cuff rotation and a natural, energy-saving stride. Designed for alpine missions where every gram counts, it shaves weight without sacrificing confidence. The Blacklight doesn’t just climb—it descends with authority. A full carbon fiber cuff and Dynafit's Ultra Lock 5. 0 system deliver strong, stable downhill performance, even in exposed or variable terrain. The Twistfit closure system dials in heel and instep retention with a quick turn of the dial, while the Dynafitter 5 liner offers out-of-the-box comfort with easy customization options. Handcrafted in Italy with a lifetime guarantee, the Blacklight is built for demanding objectives and light-and-fast perfection.
