I got these as my "beef boot" but use them for most of my winter touring - the extra weight penalty is worth the better downhill for me. Also it's done double duty inbounds with MNC bindings inbound when I was traveling and didn't want to bring two boots.
I've done touring days up to 6k ft vert on them and the faster transitions and smooth ROM helps. The hoji lock mostly works, but I do occasionally have to unlock the top buckle in order to get into ski mode without popping a hernia. I have high arches and really wide feet (107mm), and haven't had to punch them.
Dynafit Radical Pro Boot
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.

(downright abused product)
Very very pleased with these, except for the cramping stock liner (see below).
Just the right compromise of weight and holding power for my use both in- and outbounds in the Alps (6" 170 lbs advanced skier).
Hoji Lock is excellent (can mark and wear the liner locally after a while, but gluing patches solves this).
I have bunions and after 10 mm widening of the shells (I use both Radical and Radical Pro boots) and a change of liner for an Intuition, they fit me perfectly.
I would rate them 5 stars if the stock liner was right. It's not only quite flimsy, it's too short for the size of the shell (ie a 29.5 liner sold with a 29.5 shell fits actually 28.5 !) Maybe it depends on the produced batches, but I verified on several pairs at the shop and all showed the same problem. Not astonishing that people feel their feet cramped in these, even if they choose the right size of shell. Took a while for me to notice the problem, happily solved with an Intuition.

Would Grivel G10 crampons be compatible with this boot? Thoughts on finding a crampon that can be used on an approach B1 boot as well as my touring boot? The Grivel G10 seems to be the closest I've found so far.
Thanks in advance.
Thanks in advance.

Hi Matt, can't say for sure without having the crampon and boot in hand, but generally speaking, that style of attachment will work fine with these boots. A bit more of a hassle than a wire toe bail and leverlock heel, but plenty secure.

What liner would you recommend as a replacement in dynafit radical pro boots? Thanks
11/17/2025
Louis-You could use the Dynafit Dynafitter 10 liner (which is the stock 10mm liner) or you can use an Intuition Tour Tongue in a 9mm or 12mm if you want to slightly change fit from when the stock liner was new.

These boots are great! A tip for my ski-mo friends. I found the 15 deg. was too far forward and 11 not enough. I cut out the center section of the removable spoiler and ground down the edges a bit. This came out just right.

Thanks steve, I was trying to figure out why the boots felt so weird to ski, going to try this mod out myself!

Bought these two years ago from yall and the best boot I’ve toured in hands down. I want to replace the liner and was never in love with the stock one. What should I look at? A thick intuition tour wrap I had was too thick so those won’t work.

From the dynafit website it says these are iso 9523 certified. Will they work in an alpine binding like marker squire sole id? They say that they are also iso 9523.
5/16/2024
Cody, Appears so. I found - Sole.ID is Marker's most versatile binding platform. Sole.ID is compatible with Alpine, Touring, GripWalk and WTR boot soles.
You just need to properly set the AFD plate.
Note, Skimo does not sell any Alpine bindings.

Hi Cody. The Marker Sole ID technology allows those bindings to accept a boot with the ISO 9523 (Alpine touring sole) certification. So you're correct, the Radical Pro boot will be compatible.

Great boots, but there is a big but! The strap holders have a very poor design. They are too little and too thin to withstand the body weight pressure during the descent. The plastic gets firmer in cold condition and the result that they broke off at my second day….this way the straps do not stay in place and these boots are a thumb down for me!

Any speculation on if Dynafit will make an Extra Wide version?
2/9/2024
Hi Jason,
As of today, unsure, I will say if the 103mm stated last for the Radical Pro feels too narrow, there is quite a bit of modification we can do around the toe box because of the thicker materials.
We do have the TLT X extra wide at a stated 107mm last, and it is wider throughout the boot, not just the toe box. Some modifications can be done as well but the grilamid is thinner. That might be an option for you if you're looking for a touring boot that's not as beefy like the Radical Pro.

I bought a pair of the Rad Pros from SkiMo and have had them out 10 times getting the boot fit right.
They ski well and easily handle the tough conditions and lift ski alright too.
Compared to my Hoji Free boots they are a tad more upright, less forward lean, but seem to ski nearly as stiff. I had to adjust my skiing a bit for slower tip response time, but they rip!
I got them for my wider foot, I’m a tweener, with neuromas so I had to modify the boot, add a board to take up slack.
The one real disappointment is the liner.
The toes on the liner taper down at the toes and don’t have the boxed toe area to allow more toe room. Super disappointing Dynafit went with this design.
I went from a 29.5 to a 30 shell to get more toe space, and I have less toe space because of the tapered liner…with a 6mm longer shell!!
Also the Rad liner says 30, but it’s the exact same length as my 29.5 dynafit Vulcan liner.
Happy I had a pair of unused 29.5 Vulcan liners with boxed toe area I can swap out.
More fiddling with the liner fit and it will be a winner!

Is it dangerous to use these boots in a Gripwalk (but not MNC compatible) binding?

Kenneth,
These cannot be used with gripwalk bindings, the toe won't interface with the binding properly.

Hi guys, anyone using the Radical Pro with skis >110m ?
I usually drive a kastle tx103 and for that their gonna be fine. But I'm wondering if I will be able to enjoy the powder days driving my k2 116 with these boots as well.
Thanks a lot !

Federico,
You shouldn't have any trouble driving a 116 with the Rad Pro, especially on pow days. Some very aggressive skiers might find they want more support on variable/crud days, but overall the Radical Pro would be fine for a 116.

I’ve skied them on my 88 waist skis as well. They are not Downhill boots, but the do the job.

Hi guys, I just got a pair of these and they seem like the best touring boots ever. And they mostly fit great out of the box which has never happened to me before. The one hot spot is over the ankle. In walk mode the inside edges of the lower cuff seem to pinch and dig into the top of my ankle/bottom of my shin. It looks like it would be an easy fix to grind it back there a little bit and shouldn’t affect performance. Actually the way the plastic is molded it’s thinner there almost like they intended that to be a potential fit mod. Just wondering if you guys have dealt with that or have any suggestions.
12/16/2023
Hi Andrew,
I think you could grind a little of the edge material and it wouldn't hurt the boot - although I wouldn't want to make any promises about the warranty. Before removing material, I would try heating the area up with a heat gun (carefully - you don't want to bubble or melt the plastic) until it's pliable and then press those edges out a little by hand to enlarge the ankle area slightly. I did a similar modification on my Dynafit Hojis and it worked well - the ankle pocket was just a bit snug out of the box.

Hey there! Is there any difference between the Dynafit Radical men's vs. women's boots (other than colors)? My Dynafit TLT8 women's boots that I bought last year are 26.5s that flared up a neuroma that took me out for most of last ski season (boo), so I'm thinking Radicals in 27?
Thanks!
Thanks!
12/8/2023
Hi Jenna,
The TLT8 would be a similar fit to the Radical in the sense that it is wide and high volume. However, sizing up may not be necessary if you can identify the problem area and punch the shell - the Radical takes a punch very well. If you'd like to discuss your boot options in depth, fill out our online boot fitter.
With regard to men's vs women's, the difference is that the men's comes with the removable spoiler installed in the back of the cuff. This increases the lean a little bit and takes up some space in the calf area. The women's version lacks this, to make space for a relatively bigger calf muscle that might come down lower.

Hello,
I currently have a pair of Hoji Free 130 but find that there is not enough instep space for my left foot. I have narrow feet but apparently my instep on my left foot is large. I'll be returning the pair and I'm looking into the Radical Pro instead. Would the additional instep space in the Radical Pro warrant the purchase?
Thanks!

Hi Ezri,
The Radical Pro does have more instep volume than the Hoji Free 130 - quite a bit more. It is also wider. It would definitely ease pressure on your left instep, but if you have narrow feet it might be a little too wide. Shoot us an email at help@skimo.co and we can help you get into a better-fitting boot!

I am currently in a Dynafit Mercury 27.5, that fits well. Do these run a little bigger or would I be good to stay 27.5? I know shell size is the same, but boot sole length is slightly longer. Wondering if I should go down to a 27 liner.
11/27/2023
Hi Brent, these run true to size, I'd opt for the same 27/27.5 shell you currently have. Note that after a heat mold, the 27 and 27.5 liner are going to fit exactly the same.

Can you contrast the TLT 6 vs the Radical Pro? WT, flex, downhill/uphill performance, warmth etc? Thanks

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.

Hi,
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

Peter,
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.
