"What Our Gearhead® Experts Are Saying:""I raced in the DNA Ski Touring Boot on a demanding course with long vertical, and it never felt like a liability in either direction. The Race Lock transition system is genuinely one-handed and fast, and the carbon cuff gives you the kind of downhill stiffness you would expect from a dedicated race boot. The Bikini Liner molds to your foot well and keeps the fit precise even after hours on the move.""At the start line, every gram is a negotiation. The Dynafit DNA Ski Touring Boot settles that negotiation decisively, coming in at just 810 grams while delivering the downhill stiffness and climbing freedom that top-level racing demands. The carbon fiber cuff and Grilamid-carbon shell combination gives this boot a rigidity that translates directly into control on fast descents, without adding the weight that would cost you on the skin track. The Race Lock closure system lets you move between ski and walk modes with one hand and one deliberate motion, so transitions happen in seconds, and nothing slows the pace of racing. The Twist Fit System secures the heel and forefoot precisely, and 60 degrees of cuff rotation in both directions keeps movement efficient and energy expenditure low on long climbs. The included Bikini Liner, at just 110 grams, molds to the individual foot through heat forming and fits with the close, precise feel that fast descents require. Developed in Italy and built entirely in Europe with screwed components for long-term serviceability, the DNA is a boot built to be raced hard and maintained for the long run."
