Carbon, in all its glory, is sometimes hard to turn away from when incorporated into a design like the Dynafit DNA. Fast, light, and mobile? Check those boxes.
A race boot can be many things, but first and foremost, they’re light and minimalist. Dynafit’s DNA is ready to play in the race and uphill fitness scene. But this svelte, beautifully designed boot might have a comfort range when speed objectives in the mountains are in play. Here’s a first look.
In the last ten years, Dynafit has had quite a rollercoaster of boot models, features, and fits. From the classic and loved TLT6 and Vulcan to the Speed Nose years with the odd and forgettable TLT7, non-Shift compatible Hoji Free, and racy PDG. There’s now a resurgence with the excellent Radical Pro, TLT X, and DNA/Mezzalama race models. It seems like Dynafit escaped the Speed Nose era, simplified the buckle systems, and moved to a friendly, medium-volume fit that should work for many.
The DNA and the Mezzalama — the boots making up Dynafit’s race line —share a similar design layout with a Twistfit (BOA-like) lower and a single throw cord/bayonet-style ski-walk mechanism. The DNA sports a carbon cuff and carbon-loaded Grilamid lower, while the Mezalama adds about 120g for a full carbon Grilamid construction. If this sounds a lot like a Scarpa Alien, that’s because it is similar in design basics. I would place the DNA as a solid middle ground between the Alien 1.0 and Alien RS in terms of weight and harsh stiffness (the DNA feels a bit softer and more progressive than the crazy stiff Alien 1.0).
The DNA Stats
Weight Size 29.5/39: 998g with footbed.
Construction: Carbon cuff, carbon-infused Grilamid lower.
Closer Systems: Twistfit for the lower, and a race lock throw for the upper.
Sizing: Make a note Dynafit lovers, the DNA sizing brakes on the 1/2 size. The 29.5 and 30 have the same size lower.
Range of Motion: 60 degrees of frictionless striding/walking.
Liner: The liner is race specific.
Forward Lean: Adjustable 10 or 13 degrees.
Price: A cool $999.95

Looking at the DNA Sequence
The DNA boot comes with a bikini-style, backless liner, with only foam around the back of the cuff for padding. The minimalist design provides a near-frictionless walking experience but definitely impacts comfort and downhill skiing ability. I’m already looking forward to trying an Intuition Tour Mod or Palau Ultralight Race liner to get back a little of that downhill performance I imagine I’ll be missing.
I was immediately impressed with the Twistfit closure design on the lower clog. The cable system tightens on a plastic plate, providing sufficient and even pressure across the entire instep. I have low-volume feet and a low instep, and I often struggle to get boots snug across my instep, so I appreciate the ease there.
With the gaiter pulled back, we see the plastic plate the cables tighten over to secure the foot in the boot lower.
This view shows the slightly offset Twistfit knob, and the gaiter zipper pulled tight.
I’ve read a few complaints about the gaiter zipper, which makes the on/off process pretty easy/painless. My theory is that by only zipping/unzipping with the Twistfit tight, stress on the zipper is minimized, and hopefully, it will last. The upper cord closure feels robust and a bit more refined than Scarpa or Gignoux iterations I’ve played with. An aluminum catch on the front of the cuff with a molded plastic piece protects the cord and firmly snaps into place. I’m not sure I’ve totally dialed the cord length adjustment; the boots come routed with a munter hitch-esque pinching system. Based on my experience with the Alien RS, this is a set-and-forget length for me, so I’m not sure of the downside of keeping it simple with an overhand knot here.

The Fit
A few other notes on fit, the lower clog feels mid-low volume but solidly medium width. Unlike the narrower forefoot of the Alien RS, it isn’t immediately apparent that I’ll need 6th toe punches in these shells. Also of interest, the back of the upper cuff has a tight radius at the back, and my calves (pretty skinny) are too broad to seat nicely into. The calf fit seems to effectively increase forward lean in a way that I might like. However, it is an area I’ll probably add some foam to fill in the gap and get a bit more support.
The Test Rig
My main setup for testing the DNA boots will be the ZAG Adret 85 skis and GRIZZLY.SKI Olympic bindings for a super light fitness-traverse-mountaineering setup.
So long as downhill skiing on the ZAG 85’s goes well, I’m looking forward to pushing these boots with wider skis like the Blizzard Zero G 95, Ski Trab Neve, and maybe the 4FRNT Hoji if conditions are perfect. I’m also planning to do some liner experimentation to see how much friction I add with a full liner vs. the bikini and how much I can push the downhill performance of these impressive little race boots.
