Mammut Mamook GTX Boots

My beloved Zamberlan ice boots are on their last legs, and can't be replaced, at least in the US market. I have a very narrow foot, and have been trying on everything I can find in search of a suitable replacement. Women's LaSportiva Nepals are too wide in the forefoot, as are the women's Scarpa Mont Blancs. Last winter, I demo'd a pair of Lowa Vertical GTX boots, and those fit pretty well, but had a cold spot on top of the toe. I recently tried on a pair of the Mammut Mamook GTX boots, and was impressed with the fit. I found a lot of reviews of them as Mountaineering boots, but I need boots for vertical ice. Anyone use these for steep ice, up to W5? Comments on stiffness and warmth?

Hi Kathy,

Personally I have not used the Mammut Mamook GTX. However, from the picture and the spec, it looks quite similar to my La Sportiva Trango Ice Evo. (FYI, from past experience, La Sportiva's Trango has narrower forefoot than the Nepals and Scarpa's Mont Blancs.)

Since the Mamook FTX is a B3 boot with rigid sole, handling vertical ice shouldn't be a problem (I saw couple users mentioned using it for ice climbing on here too backcountry.com/mammut-mamo…{keyword}).

Based on the similarity between it and the Trango , all I know is that the Trango is not as cozy as the Nepals (Here is a good review on the two coldthistle.blogspot.com/20…)

The current Trango models that are similar to the Ice Evo should be the Trango Prime and Extreme EVO Lt. GTX.

There is someone named Mike Hasse in this post, he seems to have used the Mamook for couple seasons already mountainproject.com/v/best-…

Yeah, Bang, I read those reviews. One of the reviewers who used them on vertical ice said the Mamooks were their first boots, so I was hoping for a comparison to other more well known models by someone who had owned more than one pair. I may take a chance on them anyway, since the fit was so good. My Zamberlans started to leak water on Mt. Rainier, and are showing 4 seasons of frequent use in many ways. :^(

Kathy - One of my partners climbs in the Mamook GTX up to WI5 fine. He claims very precise and stiff enough. Lighter weight than my silver trangos. Not as warm though. He claims good to 20 degrees. Look at the Mamook thermo as well.

Thanks, gcap. If they're only good to 20F, then I'd need overboots. I'll keep looking.

I beg to differ as far as the weight of the "silver bullets" I wore some mamooks recently to climb mt. shuksan in the north cascades and recently bought some sportivas and the sportivas feel much lighter in my opinion

I love how on Mountainproject something as absolutely objective and factual as an item's weight can, in fact, turn into a subjective argument about opinions. While you are entitled to your own opinion, you are not entitled to your own facts.

The Sportiva silver trangos weigh 1730 grams per pair

The Mammut Mamook weigh 1720

No one is gonna notice a substantial difference when the difference is only 10 grams. Not too mention those weights are based on sizes, therefore if my boots (or the OP's shoe size) is smaller they are most likely lighter both subjectively as well as factually......

So to summarize


The boots that are a tiny bit heavier (the sportivas) actually feel "much lighter" (except when placed on a scale) but nobody notices this slight difference anyway, even though you did notice it, or thought you did, and made a post about it, even though the difference wasn't really there.

And then you claimed something could be lighter than something else "subjectively".

If only humans had invented some device to measure the weight of an object and assign it a numerical value. One day...

Yep. Wasn't trying to make any point whatsoever, just troll on your troll of a post.

BUT!

Hold a 5 pound weight a foot away straight out in front of you and then hold a 5 pound weight three feet away straight out.....same weight but the one closer will feel lighter subjectively in a way

I've had a pair for one full season now (scottish winter, alps summer). Like you I have a narrow foot.

Having tried several pair of top end boots from several manufacturers including La Sportiva, Scarpa, etc. when I put these on they felt like heaven.

My feet have never been cold, including a bivy during a storm below the ice section on the Frendo Spur. Originally from northern Canada what I learned from experience is that fit is massively important in keeping your feet warm. However I met someone wearing a pair during a trip to Wales last autumn and asked why he was wearing them in such an unlikely place - he replied that they just weren't warm enough for Scottish winter - I then asked how they fit - he replied 'Oh, they are way too tight, I bought them at least one size too small...' Well, enough said really...

I teemed them up with Petzl Sarkens leverlock fils and they have been brilliant even on vertical ice.

I took a chance on the unisex Mamook Thermos fitting, and they do. I followed Mammut's size table and got the mens US 8.5, which translated to the same mondo and metric size as the women's Mamook size 9's. (Normally, a men's US 8 = women's US 9). Hopefully I'll get them out on some ice this weekend.
