Arc’teryx Konseal: Technical Approach Shoe for Heavy Load Hiking

Arc'teryx Konseal Shoe

What's updated on the Arc'teryx Konseal?

• Only the leather model - Gone is the Konseal vs. Konseal FL (i.e. full leather). This is now a single model with the gorgeous Nubuck leather upper.
• More abrasion resistance - The over-lasted construction (i.e. the abrasion resistant material that wraps the upper) has been increased. Comparing to prior models you can see it comes much higher on the shoe, to give more protection from rocks.
• Vibram® XS Flash 2 Outsole - This is found on climbing shoes. Arc'teryx running shoes use the Vibram® Megagrip sole, which is softer and tackier. The XS Flash 2 is going to be much more durable over the life of this shoe if you're hiking in rocky terrain and carrying a pack.
• Carbon shank - The Arc'teryx Konseal has always been stiff, but the addition of the carbon shank takes this shoe to a new level of stability under load.

Fit & Feel: Precision Fit with a Caveat

Arc’teryx calls the Konseal a Precision Fit, but I’ve found it runs a bit large compared to other precision fit shoes like the Vertex Speed. For reference, I typically wear a 10.5 in Precision Fit and 10 in the Arc'teryx Comfort Fit. Check out my look at the Vertex Speed for comparison.

With the Konseal, I stuck to my usual 10.5 US, but I was almost tempted to size down because there is room at the front of the toe.The only hesitation is that the toe box is narrow, which would likely get too tight in a 10. Fortunately, there’s been no heel slippage, and I’ve logged long hikes without hotspots or discomfort. It’s snug and secure where it matters, with just enough flex in the upper for all-day wear.

Finding the right fit: My suggestion is to measure your foot in centimeters and use the Arc'teryx size chart to size the shoe. I have found this gives the most accurate fit with Arc'teryx. See my detailed discussion of the Arc'teryx fit in my article on the Sylan. 

Here is the Arc'teryx size chart

Heel Hold and Lacing System

I find the extended lacing system provides secure, precise fit adjustment, while the improved heel design locks in hold without sacrificing comfort. The updated heel cup is noticeable and something they also improved on the Norvan 4. See my detailed review of the Norvan 4. They've received input from testers like myself, as well as their sponsored athletes that previous versions of Arc'teryx shoes suffered from some heel slip. I tighten my laces as much as I can and have played with the extended lace positions. Ultimately I lace up to top eyelet (as opposed to the lower extended eyelet). By comaprison, I use the lower eyelet for a tighter fit on the Norvan 4, but don't find I need it with the Konseal. The integrated tongue pocket tucks away laces to prevent snags—a thoughtful detail for technical scrambling sections. I've used the lace pocket on the tongue on the Norvan and Sylan and I really like it. Other testers have been less enthused, but I find it gives a clean look and keeps lace loops out of the way. The updated heel cup is noticeable; even with a little room in the toe, my heel stays locked and I have not had any issue with toe bang up front.

Arc'teryx Konseal: Bottom line on comfort

I find these really comfortable. Leather uppers only get better with time and I know these will get more supple the more I beat them up. They're stiff (which I'll talk about more below) so these don't feel soft like a runner, but they aren't supposed to. I've done long hikes on hot days and ended with happy feet. The support is great and I haven't had sore heels or arches. If I want a softer or more responsive feel under foot then I'll reach for a trail runner, but I give the Konseal high marks for comfort as a rugged hiking shoe.

Support & Construction: This Isn’t Just a Climbing Shoe

The Konseal doesn’t skimp on support. Unlike lightweight approach shoes that feel too flexible under load, the carbon shank and firm EVA midsole offer solid stability across uneven ground. The carbon shank is the key to supporting a heavy load. If you are wearing a pack - especially on rocky terrain - you need a stiff mid-sole to prevent rolling an ankle.  The Vibram® XS Flash 2 outsole is purpose-built for rocky ground, with zoned lugs for smearing, braking, and hiking grip.

This shoe is much stiffer than the Kragg (of course) and even stiffer than the Vertex Alpine, which is designed for speed. That makes the Konseal the most stable option in Arc’teryx’s approach lineup. In my testing I'd say the stiff midsole is the defining characteristic of this shoe.

Outsole Comparison: XS Flash 2 vs Megagrip

If you’ve worn Arc’teryx trail runners, you’re probably familiar with Vibram® Megagrip—a sticky, energetic compound . The XS Flash 2, by contrast, is firmer and tuned specifically for rock traction and protection.

Vibram® Megagrip:

• Softer feel
• Better for running & dynamic movement
• Less suited for extended wear under heavy load

Vibram® XS Flash 2:

• Firmer compound for longevity
• Excellent grip on stone, slab, and loose dirt
• Optimized for scrambling and carrying weight

For the Konseal’s intended use, XS Flash 2 is clearly the better choice.

Technical Performance in Alpine Conditions

Climbing and Scrambling

The Konseal excels in fourth-class terrain where approach shoes need to perform double duty. The Vibram XS Flash 2 outsole provides confident smearing on rock slabs while maintaining enough structure for descents. The protective toe design allows for aggressive foot placement on small holds and edges.

Scree and Loose Terrain

The combination of the carbon shank and rigid upper provides exceptional stability in loose scree fields. The narrow toe profile cuts through loose rock effectively, while the supportive midsole maintains comfort during extended traverses.

Load Carrying Performance

When carrying heavy loads, the Konseal's design philosophy becomes clear. The carbon shank and supportive midsole work together to maintain foot stability and reduce fatigue, making it an excellent choice for multi-day approaches (but not multi-day backpacking) or gear-heavy single-day objectives. I did a steep hike on really loose terrain wearing the YETI Hopper M20 backpack cooler that weighed in pre-hike at 30 lbs. These shoes were absolutely the right choice over a lighter trail runner and provided much needed underfoot stability. You will quickly realize how much more support you need when you have a heavy pack.  See my full review of the YETI Hopper M20 here.

Konseal vs. Arc'teryx Footwear Alternatives

Konseal vs. Vertex Alpine

The Vertex Alpine prioritizes speed and agility, while the Konseal emphasizes stability and load-carrying capability. Both share the Vibram XS Flash 2 outsole, but the Konseal's carbon shank and more supportive construction make it superior for heavy-load applications.

Konseal vs. Traditional Hiking Boots

For multi-day backpacking where ankle support becomes crucial, mid-height hikers remain the better choice. However, the Konseal serves as an excellent middle ground when you need more support than trail runners but want to avoid the bulk of full boots.

Conclusion

The Arc’teryx Konseal is a durable, load-ready approach shoe that thrives where trail runners fall short and boots feel like overkill. They have performed really well for me, providing stability and comfort. The leather upper looks great and I think it will only get better with time. I wouldn't say the fit is absolutely perfect, but I haven't had any issues on trail. For climbers, hikers, and anyone spending time on technical terrain with a pack, this is a standout performer in the Arc’teryx lineup.
