Dynafit Blacklight Boot - 2024/25
If the TLT 8 is Dynafit’s Mozart (classical, virtuosic, precedent-setting), then the Blacklight is their Beethoven (dark, striking). Okay, maybe we’ve lost you, but we’re just really excited about this boot! Like the TLT X, the Blacklight takes what worked from the TLT 8, such as the simple ultra lock system and above-average volume fit, while also improving walking range of motion, reintroducing the toe welt, and securing heel hold via a Twistfit instep closure. The Blacklight also sports a full carbon cuff and carbon-infused Grilamid lower shell. Paired with a hyperflexible tongueless flex in walk mode, the result is a boot that walks like a race boot with the power transfer of a touring boot. For aggressive skiers, professional mountaineers, speed tourers, and everyone in between, the Dynafit Blacklight is sure to make a splash.
- Ultra Lock 5.0 integrates the ski/walk mechanism with the top buckle for efficient transitions.
- Carbon cuff and carbon-loaded Grilamid shell excel at transferring power at a low weight.
- Twistfit closure system locks the foot from the instep to the heel creating a precise and secure fit.
- Toe and heel welts are compatible with automatic crampons.
- Generous last width for a more comfortable fit.
- Pomoca soles are grippy and durable.
- Includes optional velcro powerstrap.
- Five-year “lifetime” guarantee.
Update 2025/26: Dynafit released a new Blacklight Boot. A better name would have been Ridge LT as it's much closer to a Ridge than this Blacklight.

I'm having trouble finding a boot that accommodates a wide forefoot...probably E or EE. Would this boot work for a wide foot?
3/10/2026
Hi Patrick,
This boot definitely trends wide and generally has a rectangular, accommodating shape. You could also consider the Zero G Peak - another boot in a similar weight category that works for wider feet.

hi - what is the difference between a 27.0 and 27.5 in this boot? Is it the same shell and different inner?
2/19/2026
Hi Jim,
The shell and the liner are identical - the only difference is the footbed (which in a 27 will be slightly thicker).

Compared to scarpa mastrelle 2022, which do you think is a stiffer Boot and better for driving a fat powder ski.
I know there's a significantly difference, also which is better at locking in a heel that likes to lift regardless of what I do

Hi Allen, the Maestrale is much stiffer and better suited to driving big skis. The heel pocket is also narrower which will hold your heel better.

How much stiffer are these than the TLT X? I have the TLT X, I like them enough that I want to squirrel away another pair when my current ones are toast. And hey if the blacklights are stiffer, I'll drink that coolaid.

Timber- These are an identical fit to the TLT X boot. The carbon cuff does make the boot a touch stiffer both forward flex and lateral as well.

Have tried these on next to Ridge Pro. They feel a touch shorter. How would these shells hold a toe box punch for length?

Hi Chris, they're pretty similar to other boots in the weight category. Definitely can be punched a little bit for length, but not much.

How would you compare the fit of this to the Ridge Pro?
1/16/2025
Hi Chris! I have them both on while typing this. The overall fits are very similar. If you found a good fit in one, you'll likely find the same in the other. The Blacklight Pro has slightly more volume in the heel and is a touch wider in the forefoot. Not by much, though! Both are great boots!

Is there any way to purchase the velcro strap for the Blacklight/TLT X that closes the upper cuff? It's the Velcro strap with the hook that meets up with the upper cuff buckle. Dog chewed up the ends and I'm hoping to replace them. I didn't see them on the Dynafit parts page. Thanks.

Michael, Currently, Dynafit is not offering this part.
Answer this question:
My only boot for this season (100+ days)
They look great despite the abuse, very impressed by the durability. A similar season of scrambling and hiking in F1LTs left them comically destroyed
They are the most comfortable boot I've ever had, and I have "average" feet
The boa is a lot better than the F1LT boa, it presses a plate down onto your foot. I was very anti-boa but these are a big improvement
I never found the power strap to add anything so I took it off and never looked back
CONS: there is definitely play between the upper/lower when in ski mode. The boa is fine at best. Rear cuff support could be improved. I'm trading them in for something else next season (Tecnica Peak?)

I've found that these boots have a significant amount of play in the cuff/lower pin connection above my achilles while in lock mode. I moved from the TLT8 Carbonio and there is zero play in the cuff on that boot , is this "slack" normal? its almost like the pin on the buckle is too small or the rectangular hole in the carbon cuff is too big. Both boots are the same.

Hi Zak,
With the TLT X and the Blacklight, there is a normal amount of cuff play that is noticeable when you're locked into ski mode - there is a tolerance built in to allow the system to lock and unlock reliably, the way the walk mode is designed. If you feel that the play is excessive/causing issues while skiing, you could certainly email us a video (help@skimo.co) and we can take a look!

How do they compare to Scarpa F1 LT in terms of fit?
11/20/2023
Hi Martynas,
They are a bit wider than the F1 LT all around. The F1 LT is a narrower fit while these are about average or slightly above average for the class.

Hi, thank you for your website. It contains lots of information and interesting experiences.
How would you compare these boots to the Scarpa F1 LT? My TLT 6 Performance needs a replacement (not really, but I need it ;) ), and the Blacklight or F1 LT seem to be its natural replacements. The TLT X doesn't appear as stiff in downhill performance compared to these two.
Thanks, Quique.

Hi Quique!
Both boots exist in a very similar space in regards to overall performance. They both excel on the uphill, yet retain a stiff and rigid flex pattern allowing for experienced skiers to drive bigger skis faster. They do differ in terms of fit however. For help deciding which one is for you, fill out our Boot Fitter or send us an email at help@skimo.co

Any idea how the stiffness compares to my old Vulcans and TLT6’ Performance?? I like the stiffness of those two models. The Speedfit Pro is much softer.
4/8/2023
Hi John, the Blacklight is similar in stiffness to a TLT6 Performance without the tongue. Less stiff than the beefier Vulcan, tongue or otherwise.
4/8/2023
That sounds about like the Speedfit Pro?
Oh well. I seem to be stuck with my TLT6 Performance when I want a light boot.

Is there an owner-installable d-ring for leash attachment? I saw a line on Dynafit's website that that's how things work on the TLT-X; I would have thought it would be the same here. I asked the question on Dynafit's chat (guuru, not employee) and they said "no d-ring", which kinda surprised me. I assumed it would be an optional, included item like the powerstrap.
4/3/2023
Peter,
There are a pair of D-rings included with the boot, as well as a few screws and nuts.

Is the sole replaceable? I've worn the heels on my old Freedom SL's out - they are no longer available and the heel insert on one popped out when the screw broke, probably because I'd been walking fast on hard surfaces. I've replaced the insert but it's not well protected from a repeat failure.
2/17/2023
Hi Dennis, the sole is not replaceable, it is glued to the bottom of the boot.

Would this boot be stiff enough to drive a BD Helio Carbon 104mm waist ski? For reference I am 5'10" and 170ish pounds.
I'm coming from a 2019 Scarpa Maestrale 265 b/c I want a lighter boot with this ski. Also considering the Scarpa F1 series. Mostly in the Wasatch and Uintas.

Answer this question:
After having an issue with the Twist Lock on one my TLT X boots, I was able to upgrade to the Blacklight. I got the same great fit and tourability as the X with the additional stiffness I like. I don't feel the need to add the power strap and it brings me back to my touring in race boot days. I love the simplicity of transitioning without mess with velcro. I even have pants with cutouts that permit transitioning without even pulling the cuffs up. I might have to pull those out of storage. 5 stars.
12/11/2023
Do your boots have any movement in the cuff? From bad engagement of the 'lock' on the back or pivots moving. Thanks
12/12/2023
After a season on them, I have about 1mm of play at the pivots

I am curious about the sole lenght. I have a TLT 6 in size 28.5 with a sole lenght of 307 mm. This one has a sole lenght of 317 mm in size 28/28.5 or 307 mm in size 27/27.5. Is this Boot longer now?

Hi Sebastian, the 28.5 is a 307mm, same as the six.

Do these come with a power strap, and if not is there an attachment point for one? I see that the TLT X comes with one but I don't see a power strap in any photos of the Blacklight.
12/19/2022
Based on the last bullet point of the description, it includes an optional powerstrap

Hi Ben, yes they are included but are too shy to be photographed.
