The Salomon X Ultra Winter CS Boot (available for men and women) is a lightweight insulated winter hiking boot that’s great for winter day hiking and snowshoeing. Insulated with 200 grams of Thinsulate, the X Ultra Winter Boot is rated for temperatures down to 10-20 degrees Fahrenheit with a Climashield waterproof membrane to keep external water and moisture from leaking into the boots.

The Salomon X Ultra Winter CS Boots get high marks because they combine excellent technical features without skimping on comfort. They’re lightweight (22 oz each, size 10.5M) and require virtually no break-in time to wear. The top of the boot is also lined with the fluffy fleece, found on other Salomon winter boots, that helps hold in the heat but prevents the painful rubbing that occur around the top rim.

The tongue is gusseted so it forms a continuous inner boot that wraps around your foot and prevents water from leaking in and heat loss. The lacing system is very standard with metal eyelets for durability, although there are speed hooks that lock the laces in place and won’t slip when you tie that final knot. They’re pretty cool actually.

The Salomon X Ultra CS Winter Boots have soles like a trail runner but with the toe, heel, and side protection of an insulated winter boot.
The Salomon X Ultra CS Winter Boots have soles like a trail runner but with the toe, heel, and side protection of an insulated winter boot.

There’s a front toe kick and wraparound side protection to protect your feet while hiking on mixed rock and ice or snowshoeing. The reinforced heel cup is also well protected, with a protruding ledge (like a crampon welt) to prevent rear microspike or snowshoe binding slippage when you’re wearing winter traction aids. A gaiter ring in also included above the toes.

The boots have aggressive Contragrip soles designed for traction in wet and cold conditions, with a softer flexible set of inner lugs and harder, higher density outer lugs for edging and enhanced durability. A molded midsole shank provides torsional rigidity, while a slight rocker helps keep your gait natural on long approach hikes. The heel is slightly flared like Salomon’s popular XA Pro 3D trail runners, providing extra stability.

The X Ultra Winter boots have a Climashield waterproof membrane with an inner bootie construction to prevent water and moisture from leaking into the boot. The inner bootie is seamless providing better durability and performance.

The Ortholite insoles that come with the X Ultras are simple foam and best replaced with Superfeet insoles if you prefer a more assertive arch or heel cup. I move the Superfeet Carbon insoles I use in my trail runners into these boots without any interior volume issues and that’s what I’d recommend doing if you prefer more support.

The fit is true to size, when worn with a regular wool hiking sock. In fact they fit very much like Salomon’s trail runners, which shouldn’t really be that surprising.

If you’re looking for a good general purpose pair of winter hiking and snowshoeing boots, I highly recommend giving these Salomon X Ultra Winter CSWP boots a try. I’ve been very pleased with all of the Salomon winter hiking boots I’ve used in the past and these are top-notch as well.

  1. Phil,

    Gotta ask, do these come in wides? Can you recommend a good winter boot that does. I would love to try solomans, but they all don’t fit on my hobbit feet. Called up the company and they do not plan to make any in wides. Any help is appreciated

    • This is all I can find:

      These are actually pretty good winter hikers. But the selection is very limited if you need a wide winter hiking boot that’s not built for duck hunting or framing houses.

      • Thank you so much!!

        You have no idea how frustrating it is trying to find wide boots, or trail runners for big duck feet.
        It is much appreciated!!

    • I have wide feet and have been happy with Salomon Toundra boots, super warm and super light

      • Absolutely. Those are also my cold weather/mountaineering boots. But they are simply too warm to wear above 15-20 degrees, which is where these boots come in.

  2. Good to know on the wide widths. I too now have wider feet that I used to (age56) and it hard to find the correct width.

  3. I have these! I wear them in the snow and when snowshoeing in Lake Tahoe, CA. So comfy and warm.

  4. My Oboz Bridgers died on me this weekend after hiking over to Perkins Notch. Trail was too wet for leather boots. Decided to buy these for that time between trail runners and my Toundras. 10 miles with blisteredfeet makeme tough, right?

    • Newbie mistake. I shudder when I see shoe boxes in people’s cars at trail heads. You still have to break them in, just not much. I hiked in mine for 5 miles before I did anything serious in them. With leather boots that number is 50 miles.

  5. I bought a pair of women’s Salomon X Ultra 2 mid GTX last December. Loved them for all the reasons in this article. Since buying them I’ve walked 3 Capes Track Tasmania, Routeburn and Milford Track in NZ plus a few weekend walks and have just come back from trekking for two months in Nepal – Annapurna Circuit including Tilicho Lake and Makalu Base Camp/ Swiss Camp and return. But the boots split in the last week. They now have holes on all sides where my toes flex.

    I would’ve expected them to last longer. In between those walks I’ve worn my old boots so I know how much walking I’ve done in them. I’d be interested in your thoughts?

    • First off, that’s a different boot than the one reviewed here. In fact, I’m pretty sure it’s not a winter boot at all. I normally get about 300 miles out if a pair of trail runners before the soles wear out and the toe box splits. Sounds like you got your money’s worth. Unfortunately, If you want a lightweight boot it won’t have the durability of leather, which can also be resoled. How many miles did you say you walked in them?

      • Thanks Philip
        I doubt that I’ve walked 300 miles however they’ve been very comfortable. I should’ve had a winter boot going to Makalu Base Camp and Swiss camp however at the same time my feet were never wet and despite the snow, frost and -10 degrees, I never had cold feet.

        I guess I just have to lower my expectations about how long boots should last?

      • Try slathering shoegoo around the front toe area of your shoes where the holes occurred. That will preserve the shoe longer.

  6. Hi Philip!
    I’m comparing the Salomon X Ultra Winter hiking boot with the Salomon Quest Winter GTX hiking boot for winter hikes. The shaft of the X Ultra Winter is much more flexible than that on the Quest Winter GTX. In fact, the Quest Winter shaft is stiff enough as to cause discomfort as I walk where the top of the shaft meets my shins. I don’t have experience with how leather hiking boots break in over time and so have been wondering if a stiff shaft (or ankle collar, I’m not sure what the correct term is for that part of the boot) is something that tends to soften up and become more flexible as a boot gets broken in. Would you share your experience? Thanks!!

    • I think you mean “ankle collar.” Those aren’t very heavy leather boots as leather goes, so I’d pick the ones that are more comfortable for you. There are a few thing you can do with lacing to make them feel more comfortable however. See.

      • Actually, I just wanted to be sure I understood you. Are you saying that the Salomon Quest Winter GTX boots aren’t likely to change much as they brake in because they’re not a really heavy leather boot, and as a result, you recommend choosing the boot that feels most comfortable out of the box? Thanks in advance Philip!

      • Just buy the ones that are most comfortable. If they’re not comfortable now, there’s no reason to believe that they ever will be.
