    I used these ice climbing for just one day this spring. They were fine walking a mile or two approach, and they felt great on 4 pitches of ice. I went with my street size and wore ski socks. They felt like a fine fit. It was a warm day to begin with, but my feet never got cold.

    Took them up to snowshoe for the first use. Hiked around 3 miles round trip and didn't get one blister or sore. Feet stayed completely dry while trudging through 3+ feet of fresh powder! The jacket in the Picture is also from North face and is amazing! (The purist jacket)

    Of all of The North Faces products, I'll only ever get their Summit Series because they perform much much better than their regular equipment. These boots are no exception to that. they're built well and are pretty comfortable and warm. I can say they are in fact water-proof I've stood in decently deep water with them and stayed dry the entire time.

    Fantastic Boot

    Used these on a four pitch climb in Utah. Performed really well. Utah is not exactly high altitude by mountaineering standards, but I did all four pitches at night in the single digits and these keeps me warm and dry. Offered great support while climbing, but were also quite comfortable on the approach and walk off descent.

    Love these boots!

    Used these while climbing stairway to heaven in Provo Canyon. Fit my crampons perfectly, kept my feet dry and didn't leave them aching as some boots will. Also, they're just so pretty.

    High Altitude and Happy Feet!

    This is one of the best boots I've used in years. The Verto's come with a grippy Vibram Mulaz sole and very stiff shin support, as most climbers demand from their boots. Every step feels supported and locked in place, whether they're on snow or rock. My feet aren't overly beat up when I take them off after a day on the mountain, which isn't easy for a lot of mountaineer boots to live up to. The foot funk isn't horrible either, I think we can thank Gore Tex for that delightful bonus. My favorite attention to detail on these boots are the lacing. They're super easy to work with, even with burly gloves on. Readjusting them during a break takes minimal energy and almost no time at all. North Face set a high standard for comfort and stability with these boots. Time and time again, you'll feel it pay off.

    Very Nice Boot

    I bought these boots after trying to break in my other mountaineering 6k boots (double boot) with moderate success over many months. These boots are different and the only adjustment I just needed was to replace the foot liner with one that took up more volume in the heel area (Orange SuperFeet). I consider them dialed-in after just two outings. All in all an excellent boot, well constructed and warm, up or down the mountain-well done!

    A good boot

    I've climbed all winter and so far spring in these boots and they perform as expected. I would consider these as a good boot that keep your feet dry , warm and protected.

    A good boot

    Blisters with a return policy that sucks

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

    I bought these boots in December for several climbs this summer. My attempts to break them in with two short hikes on trails proved to be painful with blisters on my heals. I went on line to return them and discovered that I have passed the 30 day return policy of Backcountry. I called customer service and was told that I have passed the 30 day return date and they will not accept them even for an exchange. The low review on these boots does not reflect the boot, they do not fit my foot. The low rating is to give you a heads up of Backcountry's return policy. I will put these boots on eBay and will no longer be a customer of Backcountry.

    I've always have had a great experience with I know you are upset, but to leave a bad review because of technicality that is your fault only makes the product look bad. For the record I am not affiliated with

    Very light, very comfortable

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: 11.5
    • Height: 6'0"
    • Weight: 190lbs

    I bought these a couple of weeks ahead of a trip up Mt. Daniel in Washington, about 5,000' gain and 17 mile round-trip. I had great plans to break them in a with a couple of short hikes but work got in the way and I arrived at the trailhead having put about a mile on them walking around the office (your co-workers will judge you). Despite that, I made the two day trip with only one very small hot spot forming and they were comfortable in everything from the 80 degree approach to the snow field traverse in crampons to the fairly technical rock scramble.

    I bought them a full size bigger than my regular show size and with liner socks and regular socks they were a perfect fit. Extremely light too, essentially weighing no significant amount more than my standard hiking boots. The only downside is they don't breathe quite as well as my summer hiking boots, however they are EXTREMELY warm so this is to be expected.

    Essentially these restored my faith in The North Face that they can make more than a t-shirt.

    Great Boots!

      I recently purchased a pair of these for a Rainier climb (August) and thought they were incredibly comfortable and required minimal break in time. To me they fit small; I usually wear a size 9 shoe and wore a 10 in these boots but would have been better off with a 10.5 as I experienced a lot of discomfort on the descent. (Not the fault of the boots).

      I wore a thin wool sock as I usually do but found my feet a bit chilled. I was disappointed by this as the temperatures were in the 30s and 40s during the climb. I think my feet would have been warmer in a larger boot.

      I've experienced many problems with LaSportiva (both hard shell and Evos) with the design of the boot's tongue. There is a break between the area of the foot and the shin and I have had horrible abrasion problems because of that. The North Face boots have a very comfortable tongue that is a continuous piece.

      Overall, I think it is an excellent boot...just not sure about the temperature issue--how much was me and how much was the boot's insulation.

      Light and solid

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

      I did what you should never do - bought these a couple of hours before a climb into pretty difficult conditions. I'm really glad I did though.

      We climbed up into knee to hip high fresh powder snow. Breaking trail and kicking steps was not a problem. Due to the worse than expected conditions we never made it to the peak but my feet were never a concern. I had solid footing and could manoeuvre well, and the S6K's never gave me any blisters or painful spots around the ankles or shins.

      I have narrow feet. They have a tight locking heel and a little bit wider toe box that I think works well for narrow to normal feet. I think if you have wide feet these will not work for you.

      I hopefully get to test these more this winter but my initial impression is that I'm very very glad I bought these. Light, and comfortable, but solid boots with a full shank that take any crampons if needed.

      Update - climbing a mix of stomped down/icy snow and fresh powder yesterday confirmed my previous impressions.

      I had packed but left my crampons and was debating climbing up as the trail started steep and icy. The hard sole, front crampon well and relatively sharp side edge of the Verto S6K, allowed me to kick hard enough to get just that little edge I needed. Performed very well and although it was a long hard climb, these were really comfortable till the end.

      Great Boot!

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

      This is my first glacier boot so I don't have a lot to compare it to. However, from what I know this seems far too comfortable to be real. I spent the last weekend exploring Mt. Shasta and practicing various mountaineering techniques in them without even breaking them in first.

      Decided to do the approach to base camp in them and had no problems whatsoever, I think they're even more comfortable than my hiking boots. They performed flawlessly with crampons on snowy slopes and kept my feet nice and warm in the high winds and sleet we had.

      TNF S6K

      Yes, I'm a dork.

      Yes, that is a Christmas tree in the background.

      That said, I hope this video helps.

      Pros: COMFORT, warmth, light weight, hikeability, comfort with crampons on

      Cons: Needs harder PVC up front, need a kick-plate type of material on the inside of the ankles.

      These boots can handle anything in the lower 48 and I wouldn't hesitate at all to use them on mountains like Orizaba or Aconcagua.

      Thank you very much for taking the time to do this review. It has saved me so much time. I was searching for a boot that would keep my feet warm in sub-zero temps. Your review is thorough and very easy to watch without all the fluff. Unfortunately the boot may not work for me as I have a wider foot and I was reading that these cater to those with narrow feet, but I'm still going to go into the city and try these on, hoping they work. That would be awesome to not have my toes go numb when I'm out hiking in the cold. Thank you, Brett.

      Footwear is an individual thing. My feet are what I would call an average size 10 in foot and toe length and average in width. For my foot, TNF and Asolo's seem to fit me the best if I go up 1/2 size. I always advise people to go and try on as many pairs as possible and to never look at the brand or price tag until you find what fits you best.

      Best advice on footware is, fit fit fit! Try on as many brands, styles and price ranges as you can! The proper fit is the most important aspect of ANY shoe/boot!

      If there is a store in your area that specializes in footware, and I'm NOT talking about Footlocker, have them size you. Choose a boot based on fit, not on looks, price or reviews. A perfect fitting boot will allow you to travel farther and the boot to last longer. Too tight and it will restrict bloodflow and you could lose toes. Too loose and you will rub holes in your heels and ankles.

      Unanswered Question

      I'm curious if these boots would be ok with an overboot for Aconcagua/Denali? I don't forsee myself doing anything bigger than these mountains and don't want to invest more than I need to knowing that I could certainly use these boots a lot in the rockies without an overboot. Thoughts?

      My hiking shoes are US size 14, are those boots going to fit me? Are they good for Aconcagua?

      Best Answer

      Mountaineering in high altitude in the Andes require double boots or 1,5 boots (above 5500m)

      These are too lightweight for Aconcagua, your feet will get cold once you stop moving above that altitude...

      I have a similar model from La Sportiva and use it for glacier approaches of rock routes in good weather conditions in Patagonia in the summer...

      what crampon's should I buy with these?? need to know ASAP!



      Check these suggestions out:

      Have tried these boots out and they fit my feet better than any other boot! However I am after a stiff B3 boot for good support, but noticed a bit of flex in the sole (as much as my previous B2 boots). This is a bit weird seeing as it is fitted with the front and back welts like a B3 boot. It's not loads but it is there - was wondering if anyone else had had issues with crampons popping off the boots or indeed if they are suitable to use with C3 crampons (i.e. I want to use the with my grivel g14s).


      I have them with BD Sabretooths with the Pro attachment, and have a bit of an issue with the toe welt due to how narrow it is in comparison to say the La Sportiva Nepal Evo. There is a bit of pivot of the toe welt in the crampon, but I haven't released. Still, I would prefer a more secure fit.

      what kind of boot is this? obviously its...

      what kind of boot is this? obviously its a mountaineering boot. but does the 6K in "S6K" imply 6000 meters, and can the boot withstand really cold temps like -20F or something. or is it only suitable for lower terrain.

      I've used the The North Face Verbera Backpacker GTX Boot for the last two winters here in Colorado in temp below -20. They worked well with a premium pair of smartwool socks. But if I were to be out more than 24hrs I would go with the S4K or S6K. IMO

      How's the sizing on these?

      How's the sizing on these?

      Best Answer

      I tried a pair to these on at TNF store and they are a europeen fit. "For me" I go 1/2 size up. My normal running shoes and 'hiking' boots are a size 10. My North Face Verbera Backpacker GTX Boot, I use is a size 10 1/2. I strongly suggest you find a retailer that carries these type of boots and try them on with the socks you plan on wearing. I notice that most all "mountaineering" boots run on the small narrow side.... IMO

      Anyone know how much these bad boys weigh?...

      Anyone know how much these bad boys weigh? are they comparable to the LaSportiva Nepal EVO GTX>

      Hey tele.savalas,

      Thanks for the question. The weight of The North Face Verto S6K Glacier GTX Boot is 1 pound, 15.4 ounces per boot. The La Sportiva Nepal boots weigh in at 2 pounds 1 ounce per boot so the North Face Verto is slightly lighter.

      I weighed my size 10 1/2 on the digital kitchen scale and each boot came in at 2lbs 2 1/4oz. That is after a hike so there may be an ounce or so of moisture in them. Comparing my S6K's to other size 10 1/2 boots, the S6K's feel lighter.
