Mammut Pacific Crest GTX - PERFECT BOOT!

  • Familiarity:I've used it once or twice and have initial impressions
  • Fit:True to size
  • Height: 6'2"
    Weight: 175 lbs
    Size Purchased: 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
  • Height: 6'1"
    Weight: 220 lbs
    Size Purchased: 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
  • Height: 5'10"
    Weight: 205 lbs
    Size Purchased: 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
  • Height: 6'0"
    Weight: 170 lbs
    Size Purchased: 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.

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.


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.

Hi Scott,

I'm intrested in getting these boots and have wide feet too(2E)

Is your father foot 2E width ?

Tried many brands with no luck, please let me know



How tall are these boots? They look like a 6 inch style but I just want to make sure. Thanks!

I hiked it these for two weeks, at least 10 miles a day, over rough terrain and sharp rock. They held up great! This is just one of the regions that I mapped.

What country is this boot made?

Mine are made in Romania.

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.

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.


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.

I are curious about the lifetime warranty...

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

Best Answer

Hey Darrin,

From Mammut's website:

"Mammut generally guarantees for all its products. However, this guarantee does not cover replacement as a result of incorrect use, normal wear and tear or fading as a result of UV exposure. The guarantee also excludes damage caused by external factors such as falling stones, rocks, ski edges, embers, fire, etc. However, in such cases we can offer a professional repair service at the customer's expense.

In the case of actual guarantee claims, the product will be repaired or replaced free of charge."

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.


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.
