Mammut Nordwand 2.1 High GTX Boot reviews and deals for sale

great boot but not warm enough

I had high hopes for this boot. I tried couple of different La Sportiva boots but in the end decided for Mammut Nordwand 2.1 boot. Couple reasons - waterproof gaiter and zipper Light boot and being very comfortable to wear, very sturdy construction for a great feel and confidence when climbing rocky terrain, work great with crampons. I wore the boot once when climbing Cotopaxi… read more in Ecuador. My team and I were lucky with weather window, clear sky, very light wind, temps just slightly below freezing (-5C ~ -10C). The boots were comfortable (in terms of pressure points) all the way up to summit, it took us 6 hours and some to summit, but here comes my disappointment. I love Mammut products and I trust their word but here they claim the boot is good for as low temps as -31F (-35C) and I don't think that's nearly the case. I don't know how they tested this but two hours into the climb I started to feel my toes being cold and around 4am when the temps were about the lowest during that climb, my toes were uncomfortably cold, borderline painful which is not what you want to be dealing with when climbing steep glacier terrain. I wore my medium thick merino wool socks so I don't think I underestimated that part, funny enough my fingers were feeling toasty in my single liner goretex gloves ($100 REI) while carrying ice axe? most of my team mates had rented older beaten up plastic double boots from local outfitter and neither of them complained about cold toes. bummer. I returned the boots.

Great first impressions

I tried out these boots along with four other options. Liked them in the following order: 5) Arcteryx Acrux - Extremely narrow, fit was terrible, snaps would likely not work in cold/snow, otherwise not a bad design. Wouldn't work as designed though. 4) Scarpa 6000 - Didn't like the wonky zipper design. Felt cheaper than the price point. Didn't seem bad, but other options seemed… read more better. 3) Boreal Siula - These would be a great budget option. A bit heavy and would take some getting used to the lacing system, but not bad at all. 2) La Sportiva G2 SM - The boot itself is very good. The liner is absolutely terrible and actually painful to wear with a nasty pinch point at the top of the foot at the ankle. I did try them with the Scarpa 6000 liners and they'd be great boots with that setup. 1) Mammut Nordwand - These were the top choice out of all the options I tried. It was a toss up between these and the Sportivas (with a different liner). I ultimately went with the Nordwands because they felt a tad more comfortable and I really like the higher integrated gaiter. The Sportivas felt like they'd need a gaiter over them, but the Mammuts won't. Haven't had a chance to try out the Mammuts in a real environment yet, but will take them up Mt Elbrus this year. Looking forward to putting them to use.

Nice boot overall

Upgrading from a plastic double boot these were much more comfortable and flexible. Two climbs of Mt. Katahdin on back to back days around 0°F they kept my temperature regulated and unblistered. Hoping to put them on some vertical ice and see how they do. I wear 11.5 to 12 and the 12 gives me plenty of room. Wide toe box! I have wide feet and these fit fantastic. Only reason I… read more didnt rate 5 stars is the fact that after one 4 day trip the rubber covering the zippers on both boots is starting to separate where the boot flexes. Also the outer layer on the seam tape in the built in gaiter is starting to rub off a little by the BOA closure (the BOA is incredible, doesnt loosen up at all) Hopefully backcountry will let me know if mammut has had any zipper trouble after reading this review.

Very bad experience in Aconcagua

I bought this boots on July 2017. Nice, comfortable and warm boots. On February 2019 I went to Aconcagua, and on the summit day, the zipper broke. Very bad experience with a freezing climate.

Hi, what is the dimension of the package? Thank you!

Does anyone have any thoughts on how warm this boot would be compared to either the La Sportiva G2 SM, or Spantik?
