If Dynafit made a Venn diagram of its (non-race) ski boot lineup, one circle would feature the beloved TLT8 Expedition boot, known for being lightweight, efficient, and capable of big days in the mountains. The other circle would be the Hoji Free 130 boot. These aggressive, huck-your-meat, stiff-as-a-2x4 boots have proven to be a delight for the freeriders who earn their turns (and drops.) But what about the skiers who want a little A and a little B? What would be the overlap of this Venn diagram? Introducing the Dynafit Radical Pro boot. This factory-made Frankenstein keeps the best traits of the Hoji Free but goes on a diet for a faster up. Don’t worry, the ingenious Hoji Lock System isn’t going anywhere. With one simple movement, you can switch your boots from a rock-solid stiff alpine boot with a 120 flex to a comfy, nimble 60 degrees of cuff rotation. The Master Step insert makes clicking in even easier. The cuff is Grilamid loaded with glass fibers for weight savings and increased durability. Speaking of up, the Radical Pro features heel and toe welts capable of accommodating step-in crampons. Once you’ve breezed to the top, just hit that same lever again to reverse course, and charge the mountain. The Dynafit Radical Pro allows you to bask in the glory of a great performance on the up and the down.

  • Ingenious Hoji Lock system transitions from climb to descend with the flip of a single lever.
  • Dynafit Ultralon liner walks incredibly well when combined with 60 degrees ROM.
  • Master Step insert makes clicking into your toe piece a breeze.
  • 120 Flex makes this a hard charging, confidence inspiring piece of footwear.
  • Pomoca outsole provides great grip to keep you upright on that ice-covered ridgeline.

Update 2023/24: Dynafit has introduced a new color palette but the boot is otherwise unchanged.

Questions & Reviews

Question from Al T
Can you contrast the TLT 6 vs the Radical Pro? WT, flex, downhill/uphill performance, warmth etc? Thanks
Answer from Jeff
Al, In every respect, these boots are different. The TLT 6 is light and narrow low volume fit. The Radical Pro is currently the widest and highest volume boot we carry. And the Radical Pro is a much stiffer more DH boot.

Answer this question:

Question from Peter
does anyone know hot to reduce flex, when the boot is really cinched down in the upper shaft? I have skinny ankles and calves, I even flipped the upper bucke 360° to cross the buckle cables to make them shorter. But with that the boot feels like beiing from concrete. If I loosen it a bit, it regains its flexibility. Maby shaving some plastics, but where exactly? What are contributes the most to the stiffness of the boot? Thanks
Answer from Emmett I

If you haven't already, make sure the cuff catch is in the tightest position. As far as lowering the flex goes, there's not much you can do, and probably nothing that wouldn't void the warranty. If you were to grind the plastic down, I would guess that grinding the front lower part of the cuff would help soften the forward flex, but that's a total guess.

Question from Chris
What are the differences (besides flex) between the Radical and Radical Pro? I'm skiing the TLT8 Exped and I'm looking for the next step up in performance and stiffness.
Answer from jbo
Hi Chris, you've found it! The Pro version has the "pants down" Hoji lock system, whereby one motion changes the lock lever, the upper buckle, and the power strap tension so you don't even need to lift your pants when transitioning. The lower-end model has those things separated so it's more fiddly.

Jonah Davis (used product regularly)
I had been searching for a AT boot that works well for my feet and gives all day comfort. I have very high arches and the the instep volume is great in the Radical Pro. My feet are medium with, so the Radical Pro is a wide in the forefoot for me. That said, I also have Morton's neuromas in both feet, so I really need to sacrifice some performance fit there for the all day comfort to avoid aggravating the neuromas, which can be excruciating. The width and relatively wide toe box of the Radical Pro fits the bill (sorta like an Altra running shoe but in ski boots). They give give me all day comfort with little to no aggravation of the neuromas. And then volume of the boot accommodates metatarsal pads on an insole, which is great and helps give an even more secure fit in the ankle and rear of the foot, making up for a bit of the spaciousness in the toe box area.

Skis great. Walks great. A bit on the heavy side but it's a beef boot. Hoji lock system is really slick. Sometimes a bit tough to get the boot lean properly aligned for the transition, but overall not bad and something you get used to.
Comment on this review:

Question from Ian Wyant
Considering making the switch from Maestrale RS to this boot due to needing a larger instep to accommodate my towering arches. I'm comfortably a 26.5 in the Maestrale, but found the Radical Pro to fit a bit snug in a 26.5 and a bit loose in a 27.5. What's experience been with getting this boot to accommodate feet that are between sizes? Should I plan to size up or down?
Answer from Emmett I

Keep in mind that the Radical Pro is wider throughout the forefoot than the Maestrale. You could consider the Lange XT3 Tour Pro, which has lots of room in the instep but not as wide of a forefoot as the Radical Pro. SCARPA uses slightly offset sizing. I'd recommend filling out a Boot Fitter so we can get you the most specific recommendations!
Answer this question:

Cyw (downright abused product)
First off: I have very high volume feet. They make boot fitters sad. Wide forefoot, high arch, high instep, fat ankles, average heel. My feet hurt in most touring boots, no matter how much punching and molding I get done. So, when a buddy told me these boots fit "like an airplane hanger" I was intrigued. No, they're not that roomy (luckily) but they do fit my weird hobbit feet better than anything else I've jammed my foot into. They fit fine, with no punches, a first for me! As far as the other important things: They walk well, although they have a little less rearward ROM than I'm used to from this class of boots(Maestrale RS feels like it has a few degrees more). I love how quick and simple the buckles are to use, and how smooth transitions are. They ski better than they should. Not the stiffest boots around, but the flex is super smooth and predictable. This is the first touring boot that I've ever been happy to ski everyday inbounds. I've swapped a booster strap in for the velcro top strap, and use Intuition Tour Wrap liners. The stock liners will probably be good for most folks, but for some reason my weird sensitive feet get along better with the wraps. No durability issues after 50-60 days skiing them. Big fan of these boots as a do-everything boot. If Dynafit came out with a stiffer and heavier, or a softer and lighter boot with an identical fit, I'd buy them in a heartbeat for inbounds days, or big objectives respectively.
Comment on this review:

Question from Scott Shatalow
Time to replace the good old Vulcans. Would the Radical Pro be a logical replacement boot? Spend most of my time touring, but still ski the hill with the same boots. The Vulcans did the job very well. Any info is appreciated.
Answer from Tristan M
Hi Scott,

Short answer, the Radical Pro is a solid replacement option for the Vulcan.

The details: The Vulcan had a higher volume fit. In the Radical Pro, Dynafit has also opted for a higher volume fit. This boot has a wider last width, and fairly roomy instep. For a freeride boot, the Radical Pro is lightweight and sports a large ROM, while packing a punch on the way down. It is a good option if you are trying to split the difference between inbounds and backcountry skiing with one boot.

Keep in mind that the fit of a boot is paramount, not just the performance characteristics. If you have more fit questions, I would highly recommend filling out a boot fitter.
Answer this question:

Question from Eduardo
Is the forward lean adjustable on these boots? Also do you have a user manual or PDF showing how to make these changes?
Answer from Gabriel I
Hey Eduardo, the forward lean can be set to either 15 or 11 degrees by removing the spoiler.

There are two removable T20 torx screws with t-nuts on the back of each boot that attach the spoiler. One of the screws also holds the power strap on, so you may want to flatten the t-nut spikes on that side when you reinstall it to avoid piercing the strap at the attachment point.
Answer this question:

Question from Kellan
I have a pair of intuition pro tour liners that I had molded and wore once in another pair of boots. Would those liners be an upgrade over the stock liner in the radical pros? I feel like I should use the intuition liners but hate the k2 a that I put them in. I have about 5 days of backcountry and 20 days of resort skiing on my dynafit liners.
Answer from Cole P
Hey Kellan, the Radical Pro stock liners are made of the same material as Intuition liners so there are only an upgrade if it changes the fit to your preference. If you rather use the Intuition liners they will work fine in the Radical Pro. I suggest re-molding them or expect a few days of skiing to break the liners in to get the desired fit.

Johan (used product regularly)
So far used these a week lift-served in the Alps and a couple of 1000 m vert tours. The TLT8, Hoji Pro Tour and Radical Pro are the only boots I have been able to use without punching for extra width.

Compared to the Hoji Pro Tour, I have to cinch the middle buckle pretty tight to keep the foot securely locked down. So definitely some added volume in the Radical Pros. Fortunately, the middle buckle placement/instep design seems to work well for me as I can go very tight without any resemblance of pain/pressure points. In the Hoji Pro Tours I experienced instep pain/pressure after a couple of hours of touring. So far I haven't experienced this in the Radical Pros.

For me, the heel hold is better in the Hoji Pro Tours, although the shells seem to be identical in the heel. I'd chalk this up to the beefier stock liners in the Hoji Pro Tours, with what seems to be added foam above the heel compared to the stock liners in the Radical Pros. The stock Radical Pro liners seem to me very similar to the TLT 8 CR-liners. I would also guess this is (at least somewhat) where the extra 5 degrees of added ROM in the Radical Pros compared to Hoji Pro Tour is coming from as well.

I haven't experienced the Hoji Lock-system "eating" into the liners as some reviews have mentioned, even though I have been riding lift based and changing from walk-mode to downhill-mode probably 20 times per day if not more. The liners have molded some space for the Hoji Lock. Also worth mentioning is that the stock Hoji Pro Tour liners have plastic coverage over these spots, to prevent damage to the liners I guess. In the Hoji Pro Tours I couldn't tour with buckles and power strap set to downhill-tightness, this is from my so far limited touring testing possible for me in the Radical Pros. Somewhat easier to change to downhill-mode in the Radical Pros due to the thinner liner, but I still have to do a "rocking" motion to gain enough momentum. In steep terrain I find this a bit challenging, but this is probably more due to my own poor technique.

All in all, very happy, but for me the stock liners need some foam around the heel and maybe instep to fill volume, or swap to Hoji Pro Tour liners/Intuitions. FWIW, MP28 in TLT8/Hoji Pro Tour/Radical Pro. Haven't tried the Hoji Frees as I suspect they would maybe be too stiff for my taste. Verifyt shows I have a 27.8 cm foot, 11.4 cm width, 7.0 cm heel width and 8.3 cm instep height.
Reply from Henri C
Hi Johan, thanks for the detailed and helpful review. Quick question, have you now done something to improve the heel pocket fit on Radical Pros and if yes how did that work out?

I am looking at these boots, but not certain that the heel fit would be right for my wide in the front and narrowish in the back feet.

Question from Oscar
How does the fit for these compare to TLT8s? Looking to beef up :)
Answer from Cole P
Hey Oscar, the Radical Pro will be the best beef boot option for a high-volume foot. The Radical Pros will have more of a performance fit than the TLT8's overall but will have similar width and instep height.

Question from Dan
I heard that the women's version of this boot differs only in color, is that true? I am not able to find the men's version in my size, only the women's. I don't care about the color, does it make sense for me to get the women's version?
Answer from Jeff
Hi Dan, Pretty much Identical. The womens version does not come with the Spoiler. Maybe a slight liner difference. We have sold quite a few to men already.

Question from Jared N
How does the fit compare to a Maestrle RS? TYIA
Answer from Ian C
Hi Jared, thanks for your question! The Radical Pro will provide greater volume over your instep as well as some additional width. Let us know if you have any other questions!
Answer this question:

Question from Rilla
Is the liner in size 26.0 "thicker" than the liner in size 26.5? I understand the shells are identical in size. If there is a true liner size difference, could a 26.0 liner be heat molded to fit a 26.5 foot, thus neutralizing the difference in line sizes?
Answer from Brett S
Thanks for reaching out, Rilla. The liners are almost identical, however, they will have slightly different molding out of the box. If you were to thermoform the liners, then the difference between the 26.0 and 26.5 would be negligible. Please let us know if you have any other questions!

Question from Guillaume J
Hi Walter, Cole,
I am wondering also because I have the Kingpin 13, but there is no official information from Dynafit that the Radical pro are compliant with ISO 9523. Whereas the webpage of the Hoji Free show the norm 9523 in its specification.
So are you sure that the Radical pro are compatible with bindings like the MNC Shift ad Kingpin 13 ?
Answer from eric
Guillaume- The Radical is ISO 9523 compliant. It will work in any 9523 binding.

Question from Peter
Is it okay to use this boot without the power strap? Would this adversely affect the Hoji locking system? I love the boots but don’t need the power strap.
Answer from Ian C
Hi Peter, thanks for your question! The power strap is intended to provide a bit more contact and control between your leg and the top of the cuff, but it is unrelated to the lock system. You can totally skip the PS if you want.

Question from Roger
what's the forward lean ?
heard about 11° or 15° with spoiler....
Answer from Zak M
Hey Roger thanks for the questions! Yes, the forward lean on the Dynafit Radical Pro boot is 15° and with the spoiler removed goes upright to 11°. Let us know if you have anymore questions.
Answer from sean b
if you remove the spoiler you cant reuse the T nuts unless you nip off the barbs otherwise the barbs will pierce the power strap material. Spoiler weighs 22g and each T nut/screw is 2g.
Answer this question:

Anthony O (used product a few times)
Normally I'm not comfortable reviewing a boot so early. But I have been on hoji boots since they came out so I can attest to the mechanism and functionality. I actually was kind of boycotting this boot because there was a super large weight discrepancy from the initial release. Fortunately I yielded because this boot is dope.

This isn't parts bin engineering, it's a new boot and it rocks. It walks like a 1kilo boot, seriously, and goes down like an Alpine boot. That simple. The strange ankle fit of the original hoji is gone, the liner is beefier than the original, I still think the toe buckle is absolutely useless but that's the only thing I don't like. The original also required you to drill the boot to remove the optional spoiler, this one however can be swapped in and out with screws to tweak your forward lean. How the tongue attaches is also different from the original hoji.

I thought the initial hatred of the original hoji was laughable, regarding the toe welt, because I've been climbing ice in semi automatics for awhile with zero problems often actually getting a more secure fit. nonetheless the radical has a toe welt for those that can't embrace change. It also increases the amount of bindings it can be used with.

It is relatively high volume and wide, finally the industry is starting to understand that most people don't have narrow euro elvish feet (take note scarpa).

All in all a excellent boot, I don't care what it weighs because it truly feels like a 1kilo boot on the foot when moving. Sure you'll notice the grams on back to back days, but on single big days I doubt most folks would. If your using this your probably using bigger skis anyway so the concern isn't about uphill speed, but rather downhill. I do think the color is boring, but that's what paint is for.

Some fellow Lycra glad brethren have tried mine and immediately bought some. Perhaps the best name for this boot is the Lycra convertor, cause they may just inspire you to become a freeride bro after a quick fit.

I may be selling my skorpius because it actually feels like it walks better, and it absolutely skis better. It may actually get down to a two boot quiver with this as the daily and Pierre gignoux mountains for weight weenie stuff and geriatric millennial racing.
