Nordwand 6000 High Mountaineering Boot

Warm, lightweight and comfortable

After dealing with frozen feet and numb toes for a couple of winters in the Canadian Rockies, in a pair of old Nepal Evo that I bought when I started climbing, I decided to get the Nordwand 6000 High ice climbing boots. I used them last winter and found them very comfortable right away, whether I was walking or climbing. They're lightweight and the gaiters keep my feet dry and warm. These boots are super warm, maybe even too warm for a mild winter like the last one. I like how easy it is to put them on and take them off with the Boa system. I hope the cables last a long time. They fit well overall, but folks with narrow heels might find them a tiny bit loose there, but you can fix that by really tightening the cables. Also, if you have wide feet, consider going half a size up – I usually wear a size 9 but got a 9.5 based on other reviews, and it was the right call. Overall, I am very happy with these boots.

Zipper catches, had to cut it twice

Familiarity:

I've used it once or twice and have initial impressions

I don’t even own these boots but my buddy does and he brought them out to climb today for the first time. I won’t speak to their climbing abilities but the zipper caught 2x times leading to a ton of faff. literally had to cut the stuck material w/ a knife then use a v-thread tool to hook it out. After removing stuckage, we got on our climb and he wasn’t impressed w/ that either. Screw these boots

Very warm, overall quality is suspect.

Initially, I was very happy with the boot. Primary use is ice climbing, secondary is for very cold days at work. After less than 20 total hours climbing in the boots, some of the heat-reflective film from the soles started peeling off. I don't think this will affect the overall warmth of the boot too much but it certainly is concerning. I wear a size 11 and have a wide forefoot with a narrow heel, the fit is true to size.

I live in the Canadian Rockies where winters can be harsh. Those boots are amazingly light and so warm. Would highly recommend.

Exaclty what i wanted

These boots are enought warm for canadian winter. I was scared to froze my toes while ice climbing but they keep me warm. No issue so far with the clip system and the boa are a big plus for me. they feel a little bit smaller then my actual foot size, i would recommend going .5 bigger (for the US foot system) then your normal size.

Great Boot, Questionable Quality

I've had the boot for multiple seasons and really enjoy them overall. Whether its a 3 hr hike to the base of the climb or climbing technical WI5, I find the boot to be incredibly comfortable and warm. The BOA system, which I am always questioning its durability, has thus far been pretty great. It takes me 30 seconds to unzip the boot and tighten and be ready for climbing vs 5 min compared to my laced colleagues. My main complaint with this boot is the quality of the pull handles/straps of the outer boot and inner sock. They are not reinforced and will tear off quite easy if pulled on too hard. I have found using a shoe horn makes putting the boots on very easy and mitigates this poor design. The other complaint I have is the main boot insole becomes delaminated from the boot rather easy. I have had it happen twice and no matter what glue/adhesive I use to repair it has been unsuccessful. Mammut was easy to contact for replacement inserts but its still an inconvenience to bring to a cobbler for them to glue back in place properly and the layers of the insole delaminate quickly under the moisture and friction of general use. Both of these issue do not effect performance but is otherwise upsetting on a rather expensive boot. The boots do feel large on your feet at first but climb well. Fit is 1/2 size larger than shoe size but BOA system mitigates that.

Looks great, but liners don't dry overnight

Took this on my first mountaineering trip up Mount. Whitney. Super comfortable. Lots of room in the toe box. Very warm until the second day. I was unable to dry out the inner liner at night. I tried everything three nights in a row. Unable to get it. Dry. Toes were slightly cold putting into damp boot. The outer gator is certainly waterproof, but it also traps in humidity from your sweaty feet. I tried venting the boots during the day. I tried taking out the liners. I tried taking out the sole from the liner putting. I tried putting the liner and the soles in my sleeping bag with me at night. Nothing worked to get the liners completely dry.

Good boots, fit's large

Good boot, but be gentle when you put them on, inner socks looks delicate, mine ripped off.

Great boot, slight overkill.

Very satisfied with boot thus far. Technical ice climber. Boot performs, but is heavy and a bit overkill for most days. Have been really happy to have them on colder days in the shade, though! BOA is super nice & convenient but I wish it did offer a bit more adjustment. Boots are pretty bulky, which is expected from a boot like this. Likely wouldn't attempt too technical a mixed climb rockin these, but for your water ice days they're pretty money.

Super comfortable out of the box. Holding up great after a handful of mountaineering trips. I'd recommend these to anyone looking for a nice double boot for mountaineering
