Bang for your Buck

  • Familiarity: I've put it through the wringer
  • Fit: True to size

These have carried me from the dusty streets of Istanbul all the way to the cold, soggy mountains of Norway, and they've performed impeccably. The waterproofing is excellent, the break-in period is almost non-existent, and the build-quality is great. Now, of course, some weather/terrain-specific boots will outperform these––insulated boots will be warmer, thinner boots will breathe better/dry off quicker, softer boots will be more comfortable, etc. At the end of the day, however, these will save you the cost of having to buy all those different types of boots, and they'll get you to where you need to go.

Great boot but ordered .5 size too small

  • Fit: Runs small
  • Size Bought: 11

my feet are a very standard size 11 and immediately when i put them on realised they were too small. Pressure around the balls of my feet, arch hit towards my heel, etc.. I am reading now that a lot of peeps wear boots 1/2 size bigger than they normally would, this is a definite must for me on this model.
Boots on the way back to backcountry, will get to see how they are with refunds- will update when i find out. Shipping out to me was excellent, customer service has been great so far. Cheers-

Mammut Pacific Crest GTX - PERFECT BOOT!

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: 11

This is the best backpacking boot I've ever worn. I wear size 11 in every shoe. Purchased an 11 and it fits perfect. True to size. Very comfortable. Unfortunately I had no break in period...but I didn't need one! Just did a 5-day backpacking trip in Yosemite through Tuolumne, straight out of the box these puppies performed very well. Excellent waterproofing, I stood in lower cathedral lake with my boots submerged up to my ankles, zero leakage. Excellent lacing system. The full, durable rand is hard and tough...perfect. Very pleased with the vibram sole. My previous boots were asolo, I like them a lot but the sole (although vibram) wasn't great. The Mammut PC vibram sole is durable and has great traction. Slightly heavier than my last boot but overall the weight of these boots is a non-issue for me...I prefer a hefty boot. Superfeet recommended, as with pretty much any boot imo.

When I have these boots on I don't have to worry about where I step...these boots win every time. For sure do yourself a favor and buy these if you're in the market for some comfortable, durable, versatile backpacking boots.

Mammut Pacific Crest GTX - PERFECT BOOT!

great rough terrain boot

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: 11.5

I got these specifically for the next two trips Im doing: Acadia NF and Glacier. Got them early to start breaking them in, and found out that I dont need to. They fit great. Coming from Salomon Quest GTX4s, I found these to be super stiff at first. But, that was just around the house. Then, I wondered if the old boots had just gotten soft over time... Then, took them out for a total of 30 miles for a group trip over some pretty rocky terrain in the Ozarks. They performed great! No hotspots (once I got my lacing tweaked). Feet stayed dry during water crossings. Rocky terrain left no visible damage to the outside of the boot or to the sole.

Awesome Boots

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: 10

From the first time I put these boots on they fit like a glove. I can wear them hiking on some more difficult treks or wear them on my MC getting to the hike. I found that the boots do fit true to size and did not take any break in time.

First pair of hiking boots, like em

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: 12

After almost rolling my ankle on a hike in the spring, twice, from trying to make other footwear work I decided it was time to do the smart thing and get a pair of boots.
These had good ratings and were on sale.
As far as usage, love them. Actually having good grip is a very pleasant change change. Waterproofing works well too.
I got them here on sale for 177. That was a bit steep but and risky from a few reviews and pictures but O am very pleased. If I get 3-5 years of good use out of them, I think ill come out alright. Not sure I would have bought them at 248.
As far as fit, they are nice, true to size.

20+ Pairs later

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size

After spending 3+ hours trying on shoes at the backcountry store front in SLC my Father decided on these. He is 6'2" ~200lbs with wide feet size 11. Shortly after acquiring these we hike Mt Whitney. He said that he didn't get any hot spots or blisters the whole time in the backcountry and those are the best boots he has even owned. He wears a liner with medium weight hiking socks. They are slightly heavy then other options we were looking at but they are well constructed and appear that they will last a long time.

The end of a long search

  • Familiarity: I've put it through the wringer
  • Fit: True to size

So these boots were the final choice in a long search for boots. I had an old pair of salomon (from like 97, I've resoled them twice now) and I wanted to replace them with something a bit newer. I actually had another pair of Salomon from BC and I tried and tried but they beat me in the end. I probably had 250 miles on them and after a 3 day trip where my feet looked like bloody stumps again, I finally gave up (thank goodness for BC return policy, BC rules). So then I decided I was gonna find a pair that fit and after trying probably 15 pairs of boots, I settled on these. I am giving them 4 stars just cause they run warm. If you are going to use them in the winter they are great, I have used them snowshoeing and love them. The memory foam works awesome for light insulation. But in the middle of summer they run a bit warm for my liking. Still they are great for what they are made for and are an excellent pair of boots. The sole is pretty stiff, so I use them with my Grivel G10 crampons and they work well on light mtn-ering stuff. Overall a great choice for all stuff except middle of summer backpacking.

Mammut, I believe you've done it!

  • Familiarity: I've used it several times
  • Fit: True to size

The Mammut Pacific Crest Trail boot is superb. The lacing keeps my foot from sliding in the boot, while still keeping good blood flow to my feet. They also have a degree of warmth to them. I'm not sure that I would wear them in the summer, but I'm more of a shoe-hiker in the summer.

Great boot

    I used this boot on the Colorado Trail. It held up well for the whole trip. The lacing system is out standing. You can form the boot for any foot type. I have narrow feet with a high arch, which is hard to fit. There is some break in time. They were waterproof for the whole trip.

    Fits better than a glove

      Great fitting and burly boot.

      the good

      The midsole support is great out of the box, I often have to use an insole.

      These replaced some sportiva Karakorums that just didn't give enough traction in hard snow and icy surfaces. The rubberized lower section is tough, I didn't notice any scuffing even after navigating some nasty sharp scree fields (a big plus over the karakorums).

      A firm sole did allow me to still job a bit with being clunky like a lot of boots and the goretex is a nice bonus to keep my feet from getting soggy.

      The bad, they don't breath great when the weather gets warm (thanks goretex). And the softer material used in the sole did tear a hole into the base of sole, which will squeak once some water gets into it. It hasn't getting into the boot though. Some super glue and they'll be good to go again.

      Great 3 season hiking boot, hang them up in the summer though unless you know its going to get wet.

      Mammut-Optimally Suitable For My Feet

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

      Mammut's website states these are optimally suitable for backpacking, winterhiking/snowshoeing, and walking. Suitable for via ferrata and mountain hiking. I was looking for a boot that could do most things. Right out of the box I noticed how comfortable the memory foam was. It reminded me of my posturepedic mattress. Sizing was right on with medium weight merino wool socks. I laced them up and headed out with my 22 mo old boy in his baby hiker. The snow was worse than crud. After some rain, melt, freeze cycles and other hikers the snow was very uneven and frozen. The last blizzard brought trees down. The boots are very lightweight and stable. My ankle rolled a few times and the boots did their job well. The traction was outstanding and the lugs are deep. The sole is dual compound Vibram. The boot is really cool looking with graphite/cyan colors. The metal clip on the tongue was not an issue at all. Laces show no signs of wear from the clip and my foot can't feel it inside the boot. The metal clip on my Lowa military boots was never an issue either. The rubber rand help with water proofing and is tough in crusty, stump, and rock filled snow. Terrain is flat to rolling in most of my hikes and snow conditions have varied, but I never had blisters or hot spots. I used the stock insoles, but will upgrade soon. They are not overly stiff and one can drive in them if necessary. They are made in Romania with "Raichle Footwear Technology". Lots of double stiching throughout. I looked at many European boots like Meindl, Salewa, and Scarpa, but decided on these d/t price and other factors above. Mammut's website helped me decide between their line of boots. They explicitly tell you what the boot was built for and so far they are accurate. I will put these through the wringer on the slick granite rocks at Devil's Lake as soon as the weather warms. Standby for further info.

      Great fit and made well.

      • Familiarity: I've put it through the wringer

      read the review about the laces getting chewed up but have not experienced anything like this with the boot. From the first time I wore them I've never had a blister or an issue with these. Seem like they will last for years.

      Close but no cigar,new model is great.

      • Familiarity: I've put it through the wringer

      The boot as a whole is very good. Stable and will wear for ever except, the is a metal guide on the tongue that will tear apart shoe laces, no matter how careful you are. Mammut corrected the problem on newer boots being sold. The picture on backcountry is of the newer boot, but their inventory, is the previous style. When they get the new boot my rating shifts to a 5 star, for durability, comfort, and the lacing system. I traded the old model for the new model, and they changed the metal for a plastic part. I hiked the Colorado Trail with these and they were outstandin. Best fitting boot I have ever had. I hike 300-400 miles a year. Little heavy and warm for summer.

      Unanswered Question

      I need an extra wide hiking boot. My current boot is a New Balance size 9 4E. What boot can I buy that will fit? I want one that is water proof (Gore-Tex) and good quality.

      Good set of crampons to accompany these boots, size 12?

      Very cool. I'm starting to get ideas for gearing up for an Adams, Baker, Glacier Peak, St. Helens kinda summer next year. Looking at sort of a minimalist approach/dual role boot and crampon combination. Would you recommend these boots with the aforementioned BD crampons to be sufficient for the task? How about a basic ice axe and trekking poles? Thank you, much appreciated!!

      Best Answer

      I like the Petzl Vasak crampons with flexlock system with these boots. I tried the BD Contact and didn't like them. They wouldn't contain the heel of the boot properly. The Black Diamond Raven Pro is a good mountaineering ice axe. For trekking Poles I use the Black Diamond Ultra Mountain Carbon Poles. They are light and fold down small when you don't want them. You have to buy to size though as they are not adjustable.

      I'm 6'3", 195 and looking for a boot for...

      I'm 6'3", 195 and looking for a boot for 4-7 day summer backpacking trips in Wyoming, Montana, etc with a 50-60lbs pack. I've had good boots in the past (Solomon, etc) and while they have always provided great stability and have kept my dry, my feet always take a beating as well. Hoping to sort that out with a new boot. What would you recommend between these and the Scarpa Kinesis Pro GTX? Or is there another you'd suggesting looking at as well? Thanks!

      Best Answer


      I like your style. Going with either of those two boots is going to change backpacking for you. Both of them are going to be much more stable under heavy loads and provide a lot of torsional rigidity and protection from rocks with the TPU shanks in them. Honestly, there isn't to much of a difference between the performance of the boots. Where you will notice a difference is going to be in the fit. I would suggest talking to one of our gearheads and possibly ordering two pairs to try on and sending one back.

      I are curious about the lifetime warranty that comes with this boot. What does the warranty all cover? What would the restrictions be on the warranty? Thanks Darrin

      Hey Darrin,

      From Mammut's website:

      Hope this helps!

      I was wondering how these boots fit for...

      I was wondering how these boots fit for someone with a medium wide foot, with minimal arch. Also, do they fit true to size or run small/large?

      I love Mammut's boots. They are relatively new to the industry but they are making a great product in short time that does well at competing with heritage brands like La Sportica and Scarpa. That being said, these boots fit very well on a standard "D" width foot. My experience from a previous pair is that they fit very accurately and I don't think they have made any changes to that standard.

      Does backcountry now carry the new version...

      Does backcountry now carry the new version of this boot, or does it still have the issue described in the review.
