Arcteryx procline climbing performance? Warmth?

Hey, if anybody has used the arc'teryx procline ski mountaineering boot and can comment on their climbing performance I'd greatly appreciate it. Lots of people online commenting on their ski performance with disclaimers that the commentators are not serious climbers, which kind of misses the point in my book. I'd like to hear from some people who have actually used this boot for what it's meant to do.

One thing I'm especially curious about things like warmth. I'd like to use them as a quiver of one for winter climbing in Chamonix (e.g. Argentiere north faces) and am specifically wondering how the warmth compares to a double boot like the Scarpa Phantom 6000s.

Also, has anybody had problems with bootfitters trying to work around the climbing specific features like the integrated gaiter or the rubber toe cap?

I only have a bit of experience with them but they feel like a slightly better koflach boot. They definitely dont climb as nicely as my acrux ar's.

In walk mode they definitely have better sideways flexibility at the ankle than any other AT boot that I've owned. But but I agree with Kevin that the ankles aren't as flexible as regular mountaineering boots.

They're quite warm, but not as warm as Scarpa Phantom 6000s. The toe box is much slimmer (see photo) so there's not as much room for insulating material. However, you could use them with insulated supergaiters if conditions are very cold. Make sure you get the "support" liner, not the thinner "lite" liner.

Be aware that they have quite a narrow last compared to the Scarpas. Many people have found that they're not wide enough or that that the fit is quite tight. That's fine for downhill skiing but not so good for keeping your toes warm when climbing.

A boot fitter put four punches in each of my Proclines and they are holding fine. According to this boot fitter (Evo in Seattle), they have punched many of them and they are realtively easy to work with.

They really aren't warm with the stock liner - about as warm as a lightweight single boot, colder than Phantom Techs. After punching, I upgraded the liner to a mid-volume Intuition liner and like the Proclines a lot more.

As others have said, they climb pretty good but not as well as a real ice boot. But they tour uphill really well, their range of motion is amazing..

You might try a vapor barrier. Haley wrote about his recent solo ascent of Begguya that he can get away with a less warm boot by using VB socks.

Sorry I can't help with the proclines, though. I couldn't even wear them cause the instep/arch is way too flat for my foot.

I use a pair, as do several of my climbing partners.  I find that they climb quite well, although not as well as my normal boot, which is a Scarpa Phantom Guide.  If I'm comfortable leading WI4 and M5 in my Scarpas, I dial it back a little bit for the Proclines, maybe like WI3/3+ and M4.  So stuff at my limit I still use my mountain boots, but I don't climb a lot of that stuff on skimo missions anyway.

They are narrow, but a fitter should be able to get you set up.

Thanks for the feedback everyone. It's been helpful.

One more question that I've started wondering about, when you fit these things, how much room do you leave for your toes? I feel like I want more room for my toes in ice boots than ski boots, and that if I fit these like ski boots I'll be bashing my toes in when front pointing. Has anybody had any problems like this with a ski boot like fit?

Guideline #1: Don't be a jerk.
