Product Preview- Arc’teryx AR Mountaineering Boots and Cassin Blade Runner Crampons

While I am excited about all the products I’ll be testing this winter I am perhaps most stoked to put this duo together and get on some early season ice as soon as possible! I’m hoping I’ll get enough field days in to have a full review post for each by early-mid January. I realize though by then a lot of ice climbers may have already geared up and wanted to share my first impressions on these before the season arrives.

Let’s start with a preliminary look at the new Acr’teryx AR Mountaineering Boots.

“A pinnacle of design for mountaineering, ice and mixed climbing, the Acrux AR is the lightest, most durable, and lowest profile insulated double boot available.”- Arcteryx.com

That is a strong statement, and it happens to be true. Let’s compare some of the other lightweight double boots on the market:

La Sportiva Spantik (88.96 oz/pair)

La Sportiva Baruntse (82.96 oz/pair)

La Sportiva G2 SM (72.22 oz/pair)

Scarpa Phantom 6000 (70 oz/pair)

Arc’teryx Acrux AR (69.1 oz/pair)

This is actually less than an ounce difference than my La Sportiva Batura 2.0’s that I reviewed last winter here.

The obvious difference here between these and my Batura’s is that these have a removable liner.

These liners “feel high-tech” in hand. I wore them around the house and they feel like a comfy slipper designed for astronauts. From arcteryx.com:

“Arc’teryx Adaptive Fit technology uses a removable bootie that employs stretch textiles and minimal seams to create an instant custom fit with no pressure. With protection extended beyond the cuff of the boot and the highest level of breathability in this category, the bootie’s GORE-TEX® membrane optimizes climate control and waterproof benefit. The perforated PE foam’s quick dry properties improve comfort, and a rubberized sole allows the bootie to be used as a camp shoe.”


Arc’teryx partnered with Vibram®  and created the AR outsole using Vibram® Mont rubber which keeps its frictional properties in sub-zero temps.

“The specially developed Vibram® AR outsole is designed for support and sure footedness. The tread and construction feature a semi-blocked toe, with anti-slip grooves, a medial climbing support zone, and heel created to provide braking on steep descents. The Vibram® Mont rubber compound maintains its performance in sub-zero conditions.”


I’ll share a promotional video on the boots and move onto the crampons I’ll be pairing with them this winter!


CASSIN Blade Runner Crampons

These are the most aggressive fully adaptable to any situation crampons I have seen. I used to love my older Petzl M10 crampons because I could swap out the front points for either dual, mono, or mono-offset. The Blade Runner’s do all that but CAMP also makes optional “snow points” so you can turn your vertical ice crampon into a multiple purpose mountaineering crampon. It really does make these incredibly versatile! My demo pair arrived set for offset mono and I plan to test them that way first with our thin early season ice conditions. Included with the crampons were two more vertical front points and semi-automatic toe bails allow for use on boots without rigid toe lugs.

Fit

How well a crampon can attach to your boot is paramount. You want them to feel like they were designed for each other and no one else. Right out of the box the fit on the Acrteryx AR was quite good. There is plenty of adjust-ability to make it “perfect” starting with three possible toe bail positions, two possible heel lever bar positions, full vertical adjustment on the heel lever itself, and, something I haven’t seen before, the asymmetric bottom that more closely follows the contours of the boot outer-sole.

Obviously we can’t talk much about performance just yet but they are definitely a very aggressive crampon! One could argue this is a 19 point crampon (20 if set up in dual front-point mode). The design looks like it will excel on steep & cauliflower ice.

The front points are made from Chromoly Steel and taper from 5mm down to 3mm. A “wear indicator” of sorts lets you know when it’s time to swap in new front points.

Well that’s it for my first impressions. I absolutely can not wait to start putting these to use this winter. I’m also reviewing the Camp Cassin X-All Mountain Ice Tools and the Camp Cassin X-Dream Ice Tools.
