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.

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.

Question from Oscar
 
How does the fit for these compare to TLT8s? Looking to beef up :)
3/18/2022
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 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?
1/10/2022
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!

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 ?

Guillaume- The Radical is ISO 9523 compliant. It will work in any 9523 binding.

12/21/2021
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.

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.

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.

Question from Jon B
 
Any advice on decision making for choosing between the Radical Pro and the TLT8 Carbonio. Is the downhill performance between the two boots substantially different?
9/13/2021
Answer from Cole P
 
Hey Jon B, the downhill performance will be significantly different between the two boots. While not as stiff as the Hoji Free 130, the Radical Pro is a powerful boot that has been designed to walk more efficiently than the Hoji Free. The TLT8 will be lighter and a more efficient tourer but may be overpowered by larger waisted skis.

Skied a 15,000 ft. day yesterday on these, about 9-10K heli assist, and the rest touring. I have to say, I've found what I think is the gold standard "Beef Boot" for the dedicated tourer (as long as it fits, yada yada yada, etc).

Weight came in 1450g per boot in 26.5 WITHOUT footbeds, which is 38 grams heavier than my Scarpa Maestrale RS. However, the walk mode is better/easier to use, articulates more freely, especially rearward, and the Hoji-lock system delivers in its claim to lock the cuff in downhill mode with no play, allowing for a truly progressive flex. This is the most "alpine like" feel in a dedicated touring boot I've ever felt.

I have a wide-ish forefoot (100mm+), a high instep, and a (maybe) narrowish heel. The footbox is roomy like many Dynafit boots including the Hoji Free, but the instep volume is VASTLY improved. Heel hold with a good liner mold is great. My biggest challenge in ski boots is usually avoiding the clamping pain on top of my foot. A simple foam padding on my instep before molding and I had no issues. I didn't have to pad the sixth toe area at all.

I was skeptical about the "set and forget" Hoji-lock system as every boot I've used in the past that claims something similar inevitably requires some fiddling on the transitions. I'm now a believer and will put Eric Hjorleifson and Fritz Barthel on the top of my list for Nobel prize winners and "People who have changed my life forever". I put the boot on at 7am, buckled it up like I was going to ski downhill, and all I did for the next 6-7 hours is lift the lever up, and down. Didn't even touch the power-strap. I'm still a little blown away. It's ironic that my fastest transitions are now on my heavy gear.

So bottom line this will probably replace my Maestrale RS as my touring "beef" boot. For reference, the other boots I ski are a F1 LT (light) and the standard F1 (everyday touring). My main goal in replacing the Maestrale RS was to find something that had a better walk mode, skied as strong or better, and be the same or lighter weight. The Radical Pro checks two of those boxes with aplomb, and is so much better at walking and skiing, that I find myself happily giving up the 38g per foot. Thinking about my day out on them, they didn't "feel" any heavier than my Maestrales, and I firmly believe that the improved articulation saves a lot more energy than simply shedding a little weight.

Chistof—

I have similar issues with top foot. How does adding a pad foam padding (adding compression) mitigate the pressure up top?

Thank you!!

Mine
9/1/2021
Reply from Christof N
 
The foam pad (usually a small oval piece of dense foam) is stuck on the top of your instep before you heat mold the liners. This is pretty standard practice by most bootfitters if you have a high instep. This helps create more space on top of the foot during the heat molding process. The pad is discarded afterwards and not used for skiing, only the initial liner mold. Hope this clarifies things.

My everyday boot has been an F1, Movement Free Tour, Dynafit TLT8, etc. and I only pull out the Maestrales (and now Radicals) for the deepest days on big skis like a G3 Seekr 110, DPS Wailer Tour 112, and I might be trying out the Voile Hyper V8 this year for my powder crusher. Anything in the mid 100s waisted category or less and I'm using a lighter boot. That's just me. I did pair them with my DPS Pagoda Tour 106 a few times this year and it was an awesome combo.

“The tyranny of choices”. So much high quality gear out there these days. The Dynafit/Hoji locking system is super intriguing.

Christof/Team Skimo—

If I could re-direct the conversation back to Maestrale RS vs Dynafit Radical Pro. How was heel hold/ lower shin fit? Was there too much space/play relative to Maestrales? Did you swap for an Intuition Liner? Any other thoughts / comments?
9/20/2021
Reply from Christof N
 
I didn’t notice any real difference between the two. The Radical Pro liner is pretty close to an intuition style foam and molded very nicely, both with the high instep issue and formed a good heel pocket that I haven’t had any issue with.

As for the DPS Pagoda 112 vs Hyper V8, the pagoda construction while still light for it’s performance, is noticeable heavier than its previous tour 1 construction and also heavier than Voile’s hyper construction so for me the Pagoda 112 is no longer a contender for a “light” powder tourer. Also, the Wailer 112 shape has such a tight side cut and is so rockered and easy skiing and playful (a big reason people love them) I have to ski it AT LEAST in a 184 or it just feels too squirrelly. So that adds even more weight and makes touring/kick turns that much harder. The V8 seems to be playful enough but not quite as “radical” a shape. And the hyper construction weight is hard to beat. That’s my .02

Hey I’m also curious about fit comparison between the maestrale RS and the radical pro’s. I have a moderately wide foot(101mm) and 26.5 cm long but I have a very high instep. Chunky club feet and huge calf’s relative to the length of my feet. I got the maestrale’s for their high volume fit and after 5/6 trips to the boot fitter and my own efforts with a dremmel removing some plastic on the bottom of the tongue that applied pressure to the top of my foot they are only tolerable for all day missions and only if I don’t use foot beds(they take up too much space). I should have sized up. The radical pros gave a wider last and that was immediately apparent when I tried them on. It looks like the shell could be easily stretched or even removed on the top if the foot. Did radical pros feel noticeably higher volume above the instep then the maestrales?
12/7/2021
Reply from Ian C
 
Hi Devin, chiming in here from the skimoco side. I would not necessarily say the Maestrales have a high volume fit. Instead of sizing up in the Scarpas I would say the Radical Pros are a great move for you. Their instep volume is certainly noticeably higher, with comparable heel hold and walkability.

How did the Mondo size compare to your 26.5 Maestrale RS? I'm on 28.5 MRS and thinking of switching.
1/28/2022
Reply from Christof N
 
The length of the Radical 26/26.5 was just a tad shorter than my Maestrale 26.5/27.0 which makes sense as Scarpa's shells break on the half size. I tried on a 27.5 in the Radical and it was obviously too big. Although shorter, I have not had to modify the Radical shell at all. I used a big toe-cap when I molded the liners to give me as much room as possible and I'd say I "notice" my toes at the front of the boot a little more than my Maestrales, but there is no discomfort or pain. The rest of the fit is great.
