Dynafit Radical CR Ski Boot - Men's
DynafitRadical CR Ski Boot - Men's

Comfortable up. Powerful down.

When you get the same thrill from the uphill as you do from the down, when being in the mountains to you is about more than counting your vertical feet or logging record times, you need a boot like the Dynafit Men's Radical CR Ski Boot. The Radical doesn't sacrifice performance for anything, and that speaks for both uphill and down. Engineered for outstanding ease of use, the Radical provides incredible ascents thanks to cuff rotation comparable to the best super-low-profile ski-running boots. Polyurethane construction and a four-buckle closure system give you the precise control and power transfer for bomber descents that those ski-running boots could never even dream of. Dynafit's Custom Ready liner provides superior comfort and thermal insulation while still providing rugged durability season after season. The Motion Lock System makes the transition from ski mode to walk mode supremely easy and fast. Dynafit's Ultra Lock Strap guarantees maximum performance and ultra-precise ski control. It also improves comfort by eliminating extra space between the tongue and your shin bone, reducing the painful shin bashing that often happens when pushing your limits.

Good point, questionable liner.

  • Familiarity: I've used it several times

With a few tours under my belt with these I'm happy to report this is a solid boot. They are not the lightest boot on the market, but I haven't found it to be an issue.

The boot offers plenty of adjustment to get the desired fit on your foot. Boot is also easy to change between walk/ski modes and both work well for me.

However, I'm on my second pair of Radical CR's due to a poor quality boot liner. On my first pair the tongue on the right boot liner tore out while I was putting my foot in. With less than a month of moderate use this was pretty clearly a defective liner. A quick return and a new pair of boots and things appear to be back on track.


  • Familiarity: I've put it through the wringer

I can't decide which is worse, switching into ski mode while skinning or switching in to walk mode while skiing. This boot, unfortunately, does both. Also, the liners are worthless: the stitching on mine blew out while heat molding them... They might look like look like a good value but I'd gladly spend more money on a functional/durable boot.

Great Boots!

  • Familiarity: I've used it several times

Disclaimer: I am 5 foot 8, 160lbs, have toured on these boots for about 25 hours, and have only skied them in untouched pow.

Going up: they are a little heavier than most strict touring boots due to the polyurethane shell, but not so much that it is a hindrance. The main problem with the boot going up that I had personally, is that the tongue would rotate and get caught inside the shell whenever my shin applied pressure on the tongue from an uphill stride. This noticeably cut the range of motion down, so I made a slight tongue modification to get ride of this problem- not a lot of work. Another minor issue, is when you are blazing your own track in deep snow, snow often finds its way inside the shell. This can often be remedied by buckling the two bottom buckles loosely, but this can be uncomfortable to climb in, and snow
sometimes enters through the sides. This is rare, but also something to be aware of. Other than that, everything is excellent. Sufficient range of motion, grippy sole, and works seamlessly with a tech or alpine touring binding. Ski/Walk mode works effectively and is never a hassle.

Going down: All buckles are micro-adjustable, and combined with a decent sized power strap, provide a great fit and feel. From walk to ski, you just lean forward, listen to a click, and your set. Though the boot is a higher volume fit, I have a 97mm last and I have been able to dial it in quite well. A pair of
intuitions go a long way with these boots. When you are actually skiing, the feel of the boot is great. It skies around a 105 flex, give or take (skies about 5-10 flex softer than my Ranger 12s), but with great response and control. Often in carbon/grilamid boots like the vulcan/backland carbon, the skier-to-snow sensation can be lost due to the rigidity of the shell material. If you need an ultra-stiff boot, this may not suffice, but if you are willing to sacrifice stiffness and lightness for a more traditional alpine boot sensation, then this is a great option. By the way, this boot is not a noodle by any means, as I can run it on a duke/bodacious combo and stomp 20fter's with ease.

Verdict: not the lightest and fastest boot up the track, and not the stiffest down the fall line, but I feel this boot compiles great aspects of both attributes, to make a boot that climbs sufficiently, and skies the fall line with a more natural feel and input/output than any other touring boot I've used, which results in a very precise feel that is confidence inspiring.

Would this boot be a good match for the Dynafit Speed Turn 2.0 binding?

They sure would, Benjamin! Tech bindings such as the Speed Turns are what these boots are designed for.

Are these boots compatible with Marker Tour bindings and the Salomon STH2 WTR bindings?
I just took them to a shop and was told that while the bindings can be adjusted to fit the boots they won't release properly. I thought the boots (or rather the bindings) are compatible?

These boots are designed to work with a pin-tech touring binding. Like the Dynafit Radical, G3 Ion or Fritschi Vipec bindings. This boot won't work with a regular Alpine Binding.

Little late, but I have ran these on marker dukes without a problem. The release is not going to be optimal, but it is not going to be any worse then cranking a pin binding up or skiing it in lock. Generally when I have these in Dukes, I try to limit risk taking for sure.

Why are the buckles on AT boats backwards?

Best Answer


The buckles on most Touring/AT boots are backwards so as to avoid opening the buckles when post-holing through the snow.

Let me know if you have any other questions!




Good Boots

  • Familiarity: I gave it as a gift but have feedback to share

These boots are stiffer than the Ones, however they are also heavier. They seem to accommodate a high arch or a high volume foot quite nice. I have never liked Dynafit liners, and these are not exceptions. So factor in a pair of Intuitions and you will be psyched.
