Alpinist Pro Auto/Semi-Auto Crampon

Take on great and icy heights with Camp's Alpinist Pro Auto/Semi-Auto Crampon. As a semi- and auto-compatible crampon, this piece of hardware switches out so that you can have the right spikes on for the right terrain. The Alpinist Pro is outfitted with asymmetrical chromoly steel serrated front points so that you can drive your toes deep into solid vertical ice and expect to stick. The interchangeable toe bail makes this crampon an easy fit for high level mountaineering boots or your less serious alpinist boots that might not have a toe welt. The auto heel clip tightens and clicks to almost any mountaineering boot with a heel welt, ensuring a stable and solid fixture.

The Alpinist Pro is reinforced down the middle of the crampon with a double bar so that when you're treading on ice, the crampon won't shake or get stuck. And when you start to pack in snow underfoot, the bouncy anti-balling plates help shed those chunks of snow from in between your front points.

  • A high-level technical crampon for vertical ice climbing
  • Eight chromoly front points keep you solidly knifed into ice
  • Comes with auto and semi-auto toe bails for versatility
  • Anti-balling system sheds snow to keep points effective

I've put it through the wringer

TL;DR: The second best ice climbing crampon I've ever owned, ever so slightly behind the blade runner, but I like certain features of this better. I purchased this crampon when it first came out, and have used it for about a season now, in terrain up to WI4+, but not on any real mixed terrain. My review is based on my comparison against the other crampons I have owned/worn: Grivel G22 Black Diamond Cyborg Petzl Lynx Camp Blade runner The Good: This crampon borrows a lot of the features of the blade runner, and improved on some of them. Unlike most crampons on the market, the Alpinist Pro is a constructed of only two pieces - a front part (front points, secondaries etc - painted orange) and a combined heel-linking bar part (painted black). It's two piece construction is stiffer than any 3 piece crampon I have ever tried, which helps in steep terrain. It fits asymmetric modern boots very well, without the front points being aligned - "toed in" which I have found with other crampons (Lynx), so when you kick the ice - both front points penetrate consistently and evenly. The heel-linking bar part is not flat like most manufactures , but has a lip and engages the heel tread of the boot, helping to drive the crampon into the ice. Additionally, the heal-linking bar part also has small tabs turned upward on the side (like almost all other crampons) which was lacking on the blade runner, and keeps the heel of the boot in place with greater consistency than the blade runner. The linking system is a real pleasure to use, and makes adjustment very easy and can be used with gloves - this is a big improvement over the blade runner, which was difficult to adjust with gloves. Camp has also redone the heal bail clamp of this crampon, getting rid the screw adjuster that is universal in almost every other crampon, and opting instead for 3 bail locations, low, mid, and high. While you lose some of the micro adjust-ability, when combined with the linking system, you can still achieve excellent fit and confidence inspiring attachment. The anti-balling plates are about as functional as any anti-balling plates it seems. They work well 90% of the time, but under just the right conditions, you'll be stuck knocking snow off of your crampons. The Alpinist line of crampons has modularity - the Alpinist Auto is more of your classic mountaineering crampon (horizontal front points). If you purchase the Alpinist Auto - and get the Alpinist Pro front part, you now have two crampons for the cost of 1.5 crampons - similar to following Petzl in this regard. However - you cannot (to my knowledge) buy just the Alpinist Auto front part - which is a bit of a drag. Less than Good: The price point is expensive for a crampon that you cannot convert to monopoint, and some of the reason that I like it less than the blade runner. Also the while the secondary points are very well placed on this crampon, they are not quite as good as the blade runner. These are a little heavy to be sure - at 2.2 lbs - there are lighter crampons on the market. For these last three reasons the Alpinist Pro loses a half star.

Hi Michael...what are your thoughts on using this as an all-around crampon? I understand the vertical front points might make travel on glacier/less steep terrain not as easy as horizontal points, but I would like a system that can also be used confidently when I do ice climbing. Would it be a mistake to choose a crampon like this? Let say, for example, on some climbs like Aconcagua?


How will these fit boots that are curved in? As they have only one slight degree of freedom, will they go forward straight along my toes, not through the front of the boot? Alternatively, maybe this is the desired behavior and they shouldn't curve along the boot but go straight forward into the ice?
