Great Boot so far

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

I just finished my first short backpack trip in a new 2013 pair. 10 miles with 3800' of elevation change and lots of rocks and roots in Glacier National Park. The fit was perfect out of the box. Not one blister and it was 90 degrees. I'm 5'11" 175 lbs and wear a size 11. I found they fit size-wise like other Salomon's (and I own many pairs in different styles). I did not test waterproofness, so no comment there. I did find carrying a 35 lb pack over sharp rocks and roots to be no problem at all. I've seen poor reviews stating a lack of a more rigid foot-bed that allows you to feel rocks through the bottom. They do have an athletic shoe-type feel, but support and protection are top-notch. They feel reasonably light and the sole seems to have this forward propulsion type feel. Traction is great, never slipped once. I have narrow feet with low arches and found them to be a great fit with plenty of toe-box room. I'm replacing some LL Bean Cresta leather hikers that are great but much stiffer underfoot and heavier. Highly reccomended

Not waterproof

Just took my boots for the on my first hike in rain. Went hiking in the backcountry here in Norway with rain showers and wet grass for 5 hours. After 2 hours I was soaked on my socks. Do not buy these boots as they are not what they say they are. Stay away. Very disappointing.

Responded on

Were you wearing shorts, or pants that weren't waterproof? Are you certain the water wasn't coming in from the top?

Dont buy this boot

I thought I was buying a quality backpacking boot. The first time I tried to lace them up the lace grommet pulled out of the side of the boot. I returned them for a refund. The pot metal used to hold the eyelets on is cheap. Made in China go figure.

Responded on

Climbing gear, shoes and clothing are Made in China, so?
The quality is in the hand of the company.
Every assembly line have from time to time defects. it is imposable to do 100% best
Salomon make a good products but from time to time like all manufacturer they have defects

Comparing this boot with the Wings Sky GTX...

Comparing this boot with the Wings Sky GTX 2. Do they both work well with standard ice crampons??

Responded on

I have a pair of cosmics that barely fit (heel wise) into my camp usa stalker universal crampons and I think they are great! Wish They were a little more stiff for 35 degree+ slopes, although.

Solid Kicks

Took these on a 40 day hiking expedition in the southeast fresh out of the box. Not a single blister the entire trip and the comfort level right out of the box was outstanding. Helluva boot

What's the difference between this boot...

What's the difference between this boot and the Quest 4D GTX?

Responded on

Well, the Quest uses burlier materials in the upper making it heavier but also more durable. The Cosmic is lighter. Otherwise they are pretty much the same.

Salomon 4D GTX Boot Review

As you would expect, outdoor gear has evolved and benefited from technology over the years. At least that’s what I believed with all things EXCEPT hiking boots. I surrendered to the idea that boots were just one of those pieces of gear that required constant attention and modifications to avoid painful feet.

Without naming names, my last 4 pairs of boots were nothing short of medieval torture devices. For decades I thought my feet were cursed to suffer on any backpacking trip over 5 miles. But for the first time in literally decades I can enthusiastically say that my backpacking dreams have been answered with the Salomon 4D GTX boots.

I hiked 20+ miles during a recent 3 day weekend warrior excursion up to Yosemite. We ventured up to Ten Lakes and the surrounding basin. The hike in, really put these boots to the test since I had an overloaded backpack that would make any seasoned Sherpa very proud. Lets just say, I like to eat and drink very well in the backcountry on shorter trips so the pack gets heavier than I care to admit.

The bottom line is that these boots got better and better with each passing mile. Like a good baseball glove, these boots were better after the trip than before it started. I’ve been a huge fan of Salomon shoes for many years but never tried their hiking boots. I was hoping (actually praying) that the boots would fit my feet as well as the shoes. I can honestly say that I will never own another pair of shoes OR boots other than Salomon.

The 4D GTX Boots kept my feet fresh, strong and pain free during the entire trip. The boots provided great support throughout the entire boot including the foot beds. Traction was excellent in varied conditions and the laterally support was very confidence inspiring. The waterproofing provided great protection against the elements without suffocating my feet and creating hot spots. These boots were very versatile. They were light enough to trail blaze with a Camelbak but can still handle any pack you dare to carry.

Thank you VERY much Salomon
