Kilian Jornet’s NNormal had a robust presence on the 2024 The Working Occasion launching on the market the Kboix 01 with modular midsoles (examined by Sam , the Brut for mud and snow, an up to date Kjerag 2.0 with extra stack, new TPE foam and a brand new lighter higher in addition to a Tomir 2 GTX with a PFAS free Gore-Tex Invisible Match higher.
NNormal Kboix 001
($240 with selection of two midsole, $40 for extra midsoles)
Sam: The Kboix represents a daring try to not solely lengthen the flexibility of a single run shoe through the use of interchangeable midsoles with completely different journey (and whilst I came upon match traits) but in addition lengthen the lifetime of run footwear by making them not solely sturdy however with replaceable key elements.
The important thing function of the Kboix are the three interchangeable midsoles you select a mixture of any 2 initially with possibility so as to add a 3d or substitute for $40.
The supercritical foams of every of the interchangeable midsoles are completely different. Supercritical foams imply decreased weight and better power return in comparison with old fashioned EVA’s till just lately present in street and path footwear:
Kb 1 Delicate-supercritical EVA
Kb 2 Reactive-supercritical TPU
Kb 3 Bounce- supercritica PEBA
Together with 150 different fortunate runners world huge, I used to be capable of check the close to manufacturing model over a number of months with suggestions offered to NNormal about remaining changes. All photos right here besides the one beneath of the ultimate model are of the close to manufacturing model.
In my case I requested for an extended tongue and shorter laces and that’s about it. Others requested a barely completely different achilles collar angle which is now included however the early model was effective for me.
And earlier than this remaining check Kilian acquired some “stable” prototype testing throughout his epic latest “Rediscovering the Pyrenees” journey the place he ascended 177 three-thousand meter peaks with over 480 km of distance and over 43,000 meters of climbing. I feel I catch glimpses of Kboix in the NNormal’s video recap of the journey HERE
Utilizing the interchangeable midsoles I ran them on roads and exhausting packed paths utilizing the Delicate and Bounce supercritical EVA midsoles and took them trekking in France for 3 days in very moist circumstances utilizing the Reactive midsole ( which together with a faster rebound additionally dialed within the match for extra technical terrain) in addition to my throughout favourite midsole the Bounce.
All three midsoles are energetic and supply loads of cushion. They have been even glorious on the street and rail path with the Delicate or Bounce midsole. Having the ability to change the journey and to a sure extent the match on the go is a recreation changer. The midsoles should not that simple to take away and insert. Altering them is nonetheless doable in a minute or so, much less in case you are stronger!.
To not fear the midsole as soon as in doesn’t transfer with the excessive sidewalls, part of the Vibram MegaGrip outsole protecting them safe and your foot secure even in very moist circumstances. ]
My pre manufacturing pattern with Delicate midsole on board weighs 9.7 oz / 275 g in a US8 which is a half dimension down from my “regular”. Initially cosy, they did get stretched after use in moist circumstances with all midsoles so I might say they run a half dimension giant by way of quantity. The Reactive match is snugger and nearer to true to dimension than with the Delicate and Bounce within the shoe.
Kboix is a really properly executed new strategy to creating a single shoe extra versatile for a number of makes use of from street to path operating to mountain climbing/trekking whereas prioritizing sturdiness and interchangeability, which in the long run makes for extra sustainable footwear. As such the Kboix units a excessive bar

NNormal Brut
NNorrma Kjeragl Brut – the Kjerag goes rugged! Designed for moist, mud, and muck – take a look at that outsole.. 6.5mm lugs!
The higher is designed with the concept of water in / water out. There are few if any absorptive supplies within the shoe.
Water absorption was a weak level of Kjerag V1, needs to be resolved with this mannequin and in addition by way of updates to the Kjerag 2.
✅ 28.5/22.5mm (6mm drop)
✅ Eexpure supercritical EVA (similar as Kjerag V1)
✅ Vibram Megagrip Litebase (6.5mm lugs)
✅ Matryx higher w/ drainage ports, neoprene tongue
✅ 230g / 8.11 oz spec weight
Out there Fall 2025
Mike P: This lugged-out Kjerag mannequin looks as if a slam-dunk for NNormal. Many have been clamoring for a beefed up outsole on the Kjerag. Paired with a light-weight Matryx higher, the extra weight from the beefy outsole balances out to a light-weight and rugged SG (comfortable floor) beast. Be aware that this mannequin makes use of the Kjerag V1 midsole compound, however that ought to work simply effective on comfortable floor.
NNormal Kjerag 2
NNormal Kjerag 2 – simply revealed at TRE! Some updates that needs to be interesting throughout the board for each elites and “non-Kilians” alike.
I spoke with Dakota Jones extensively about this one and we’re on the identical web page with this replace. The additional 2.5mm foam underfoot and new TPE compound ought to assist the shoe really feel much less minimal and lengthen its vary and flexibility.
✅ New supercritical TPE foam compound
✅ +2.5mm stack improve – heel & forefoot
✅ 26/20mm now
✅ Knit tongue with safer gusset
✅ New, thinner single-layer Matryx higher
✅ Smoother material footbed (nonetheless no insole)
Out there July ($195)
Mike P: Once more, one other slam-dunk replace from NNormal. The unique Kjerag is kind of minimal underfoot, even including 2.5mm of froth, it’s nonetheless one of many extra minimal “tremendous footwear” in the marketplace proper now. Updates to the higher ought to improve the match and primarily scale back water retention. V1’s microfiber-type inside did appear to carry water and will get a bit clammy. The brand new higher can also be a lot thinner (single layer) which ought to enormously help breathability. Midsole foam strikes from supercritical EVA to supercritical TPE. Extra to love!
Tomir GTX 02
Similar midsole/outsole unit as common Tomir 02Sustainable PFAS-Free Gore-Tex Invisible match higherLacing will likely be adjusted to be in-line (not facet/offset). (Lacing of normal Tomir 02 may even be adjusted to be in-line – to match the GTX mannequin)
Mike P: I acquired to check out the non-GTX Tomir 02 throughout NNormal’s group run at TRE. Btw, what a enjoyable time – I acquired to speak with Jimmy Elam on the way in which out, and Dakota Jones on the way in which again! I beforehand examined the Tomir 1 and the 02 felt a lot better. Lighter, extra versatile, with the higher was undoubtedly much less restrictive. This GTX model, releasing in Fall 2025 will present a rugged cold-weather possibility for these slushy/snowy fall/winter circumstances. Dakota has been racing within the Tomir, so it’s greater than only a coaching companion to the Kjerag.
