Dynafit Cramp-In Crampons

I have size 23.5 TLT8 boots and the smallest setting on these crampons is too large! Do you have any suggestions for how to make them smaller? I tried putting a twist in the cables, which allowed me to climb a moderate slope but felt sketchy.

i’m on my second season with these and they’re pretty solid. i wore them on the north ridge of kulshan in late july and felt like they were just enough to squeak up a pitch or two of front-pointing on easy alpine ice. the black plastic clasp has failed a couple times but hasn’t affected the crampon/boot connection (although it does feel a bit unsettling to look down and see crampon straps dangling). for everything less than sustained ice, they’re just enough pointy bits.

I cannot find any instructions on how to install these...?

Whoever did their own boot piece installation - did you guys do anything to seal the holes in the boot after drilling? I am worried that the boot will start leaking

I’ve used these crampons a handful of time’s now. The snow conditions leading to the booter seem to make a big difference on whether or not they ice up. I had a few occasions that they side right in and one that was about a half hour of fighting the ice on the bottom of the boot before finally getting it to go. After the bad experience I took a bit of time off the mountain to figure out exactly where to scrap and how to line them up (the trick seems to be having the inside of the crampon lined up with the inside of the boot and the white dotted line on the crampon just in front of the toe of the boot then slide back of course this is just my boot probably different with other sizes) so that even if there is a little ice in the boot receiver, getting it lined up then the backward pressure of the lever is enough to clear the remaining ice in the hole. After figuring this out I’ve been able to clear ice a lot faster. If it was easier to get on in all conditions this would be a five star review.

Light enough that it doesn’t add much to the pack, plus easy to adjust, plus an innovative mount that keeps the toe solid and secure (once it’s in) equals win for Dynafit.

I return yesterday from doing the Sierra high route east to west. I bought these for the trip as they are very packable . I did the installation myself, as other reviews state if you are somewhat mechanical you can do it no problem but there are no directions provided .

Adjusting the size is pretty simple but I would make sure to have them dialed in at home before doing it in the field . A real wrench works better than the other crampon like the video shows but it does work if need be.

As far as icing i had no issues but it was a concern of mine . Also after a lot of hiking a d scrambling in rocks there was no damage to the insert . I think the insert will out last the shells .

Performance these meet my expectations , we did not encounter bulletproof ice so I can’t speak on how they work on those conditions. They are solid on the boot when adjusted correctly .

The reason I gave them 4 stars instead of 5 is because these are not easy to get on when in the field. I would make sure and put these on before you absolutely have to. This might cause other issues by being a little pre mature but it could save you. Trying to find the insert and lock them in during bad conditions or over exposure is a challenge . I’m sure if you used these a lot you would eventually get the feel for it and it wouldn’t be as much of an issue. A tooth also broke off with not that much use. This could be from me being 200lbs plus 75lb bag and a bad post hole on a rock so that isn’t to much of a concern but it did happen.

Hey Guys, just checking back to see whether the extra boot hardware (for a second pair of boots) is available yet? Thanks, John

I love the idea of this system for my Hojis, but am a little concerned about the sole adapter icing up or having some other kind of complication in the field. Pros/cons of using the cramp-in for larger ski mountaineering objectives as opposed to an adapted automatic crampon?

I like them so far. Haven’t used them yet. Super lightweight. Seem to be pretty solid for aluminum. We’ll se how they hold up. I was able to install the hardware on the boot sole pretty quickly and without any hangups. I wouldn’t attempt it if your not mechanical though. Wish they sold extra mounting parts for the boot sole though. Not very practical if you have more than one pair of Dynafits...

Can I buy a second set of boot sole hardware so that I can use this with either of my boot pairs?

Do these come with the adapter needed for the sole of the boot?

I used these all of last spring and can't wait to put them on my boots again this year. I used them on steep spring snow, deep boot packs, and short easy ice steps without feeling insecure.

Getting them on is really easy and once on the boots you almost forget you have them since they are so light. They have turned into my go-to crampon for my ski-mountaineering objectives where I would bring all aluminium crampons. They are the perfect pairing with a PDG2, TLT7/8, or HOJI Boot (excluding the Free).

**Disclosure - I work as a rep for Dynafit**

Is it possible to install the needed hardware on the PDG boot, or just the PDG 2? I have the PDG and the Hoji, and am wondering whether these crampons will be compatible with both pairs of boots (whether I can install the toe piece hardware to both pairs of boots).

Will this crampon work with the Dynafit PDG boot?

Does this require installing an extra piece onto the sole of the TLT7 Performance? I can't see anywhere that looks like it would attach on the sole of my boot.

Does the dynafit cramp in crampon work on the tlt7 expedition boot?
