NNormal Running Shoes Explained: History, Technology And Models
NNormal is one of the newer names in performance running footwear, but it has already established a distinctive position within the trail running market. Founded in 2022 through a partnership between Spanish footwear company Camper and mountain runner Kilian Jornet, the brand combines footwear design experience with specialist knowledge of demanding mountain terrain.
Unlike major running shoe manufacturers that produce extensive collections for roads, tracks and trails, NNormal concentrates on footwear designed for running in natural environments. Its shoes cover everything from accessible woodland paths to demanding mountain races, with different models developed around particular terrain and distances.
The current collection is built around three main families. Kjerag focuses on lightweight performance and technical terrain, Tomir provides protection and versatility for longer
mountain runs, and Cadí offers a more accessible option for everyday trail running.
This guide explores NNormal's background, explains the technology behind its running shoes and examines the main models available to runners. It also looks at fit, heel drop, sustainability and the differences between the current models.
Who Is NNormal?
NNormal was established in 2022 by Camper and Kilian Jornet, bringing together two organisations with different but complementary backgrounds. Camper is a Spanish footwear company founded in Mallorca in 1975, with an established history of footwear design and manufacturing.
Jornet is one of the world's most accomplished mountain runners, known for his achievements in trail running, ultramarathons and mountaineering. His experience of competing in demanding mountain environments provides an important influence on the development of NNormal's products.
The partnership developed around the idea that performance footwear should be designed to last rather than encouraging runners to replace products unnecessarily. Durability, functionality and reducing environmental impact became central principles of the new company.
The name NNormal reflects the brand's intention to challenge conventional approaches to outdoor equipment. Rather than producing a large number of overlapping models, the company has concentrated on developing a relatively small collection of specialist footwear.
Its first running shoes were the Kjerag and Tomir, which established two different approaches to trail running. The subsequent introduction of updated models and the Cadí family has broadened the collection without moving away from its original mountain running identity.
What Makes NNormal Running Shoes Different?
NNormal develops its running shoes specifically for outdoor terrain rather than adapting conventional road running footwear for trails. Its products are designed around the demands of uneven surfaces, changing gradients and prolonged exposure to challenging conditions.
Outsole traction, secure uppers and resistance to wear are important considerations throughout the collection. These characteristics reflect the demands placed on footwear when running over rocks, loose ground and other unpredictable surfaces.
The brand also places considerable emphasis on product longevity. This influences its choice of materials, construction methods and approach to repairs, with the intention of keeping footwear usable for longer.
Another distinguishing feature is the relatively focused product range. NNormal has avoided creating numerous models with only minor differences in cushioning or intended use, instead developing footwear for clearly identifiable running requirements.
Kilian Jornet's involvement also gives the company access to extensive experience of mountain racing and technical terrain. However, the collection is not exclusively intended for elite athletes, particularly following the introduction of more accessible models.
How Do NNormal Running Shoes Fit?
Fit varies across the NNormal collection because its shoes are designed for different types of terrain and running. The shape of the upper, amount of internal space and level of foot security differ between models.
The Kjerag family has a relatively secure performance fit intended to hold the foot in place when moving quickly over uneven ground. The Kjerag 02 retains a medium fit with room around the toes, while its lightweight upper provides support without unnecessary bulk.
Tomir 02 places greater emphasis on protection and security during longer mountain runs. Its construction is intended to keep the foot comfortably positioned when negotiating rocks, uneven paths and steep gradients.
Cadí has a more accommodating shape, with a wider forefoot and additional internal volume. It is particularly relevant to runners who find more specialist mountain running shoes restrictive.
NNormal has also developed different fits for men's and women's Cadí models, taking account of differences in foot shape rather than simply changing the size. This reflects the company's intention to make the model suitable for a broader range of runners.
As with any running shoe, the most appropriate fit depends on individual foot shape. There should be sufficient space for the toes to move naturally, particularly during descents, without excessive movement through the heel or midfoot.
What About Heel Drop?
There is no single heel drop across NNormal running shoes. Different models use different offsets according to their intended purpose, although the current collection generally favours relatively moderate drops suited to trail and mountain running.
Heel drop describes the difference in height between the heel and forefoot. The Kjerag 02, Kjerag Brut and Cadí all have a 6 mm drop, while the Tomir 02 uses an 8 mm drop. These differences reflect the distinct cushioning platforms and geometries used across the collection.
The figures can also change when a shoe is redesigned. Runners moving between NNormal models, or upgrading from an earlier generation, should check the current specifications rather than assuming that the heel drop has remained unchanged.
Heel drop should not be considered in isolation. Stack height, cushioning, flexibility, rocker geometry and the overall shape of the shoe all influence how it feels while running.
What Is EExpure Cushioning?
EExpure is NNormal's cushioning technology, developed to provide responsiveness and durability in demanding running conditions. The original construction was intended to deliver energy return while maintaining a relatively direct connection with the ground.
This is particularly relevant to technical trail running, where runners need to respond to changing surfaces. The balance between cushioning and ground feel can influence how confidently a runner moves over uneven terrain.
The Kjerag 02 uses an updated formulation known as EExpure+, incorporating supercritical TPEE foam. This material is designed to provide responsive cushioning while retaining the lightweight characteristics required for faster running.
NNormal uses different foam constructions elsewhere in its collection. Tomir 02 incorporates supercritical EVA cushioning, while Cadí combines a supercritical foam midsole with a cushioned footbed to provide comfort over longer outings.
The way the foam is incorporated into the shoe is also important. Kjerag 02 places the foot directly over the midsole without a conventional removable insole, creating a different underfoot construction from models using a separate footbed.
Midsole thickness, shape and flexibility all influence the experience of running in a particular model. The cushioning material is therefore only one element of the overall design.
What Is Vibram Megagrip?
Vibram Megagrip is a specialist rubber outsole compound used throughout NNormal's running shoe collection. It is designed to provide traction across different outdoor surfaces, including dry trails, wet rock and uneven mountain terrain.
This versatility is particularly important when conditions change during a run. Some NNormal models also incorporate Vibram Litebase technology, which reduces outsole weight while retaining the traction characteristics of the rubber compound.
The pattern and depth of the outsole lugs determine how effectively a shoe engages with different surfaces. NNormal uses several configurations, ranging from the relatively shallow 3.5 mm lugs of Kjerag 02 to the aggressive 6.5 mm design of Kjerag Brut.
Tomir 02 uses 5 mm lugs for more demanding terrain, while Cadí has a 4 mm profile suited to smoother trails and rolling countryside. These differences help distinguish the intended conditions for each shoe.
The most aggressive outsole is not necessarily the best choice for every runner. Firmer surfaces and loose, muddy ground place different demands on footwear, making the intended terrain an important consideration.
What Is Matryx Technology?
Matryx is a technical woven upper material used in NNormal's Kjerag running shoes. Its construction combines lightweight fibres within a structure designed to balance durability, breathability and foot security.
This makes it particularly suitable for performance footwear where reducing unnecessary weight is important. The material also needs to withstand repeated contact with uneven and abrasive surfaces.
The Kjerag 02 incorporates a lightweight Matryx upper intended to maintain a secure fit during faster running. Its construction allows air to circulate around the foot while providing resistance to abrasion.
Kjerag Brut uses a more open Matryx Micro construction designed to encourage water drainage. This is particularly useful in muddy conditions or when crossing streams, where keeping water completely outside the shoe may be impractical.
Different versions of Matryx allow NNormal to adapt the upper to the conditions in which a shoe will be used. The material forms an important part of the company's approach to combining lightweight construction with the durability required for mountain running.
Does NNormal Make Neutral Running Shoes?
NNormal's running shoes are generally designed around neutral foot movement rather than conventional motion control or corrective stability systems. The brand does not divide its range into neutral and stability categories in the same way as many road running manufacturers.
Instead, its shoes are developed around terrain, distance and performance requirements. This means runners are more likely to choose between models according to the surfaces they encounter than according to traditional road running classifications.
The Kjerag 02 is an example of a lightweight trail shoe without conventional corrective stability features. Its construction focuses on responsiveness and secure footing rather than attempting to influence how the foot moves during running.
Other models use different cushioning platforms and upper constructions, but this does not automatically make them stability shoes. Runners looking for neutral footwear should therefore compare fit, comfort and intended terrain rather than relying entirely on traditional classifications.
Does NNormal Make Stability Running Shoes?
NNormal does not currently offer a dedicated range of traditional stability running shoes comparable to those produced by major road running brands. Instead, stability is addressed through the overall construction of each model.
Platform width, upper support, cushioning geometry and outsole design all influence how securely the foot is supported on uneven terrain. These characteristics are particularly important when running across surfaces that are not consistently level.
This approach reflects the requirements of mountain running, where the foot frequently lands at different angles and encounters unpredictable surfaces. A shoe must provide sufficient security without unnecessarily restricting natural movement.
Runners who require a particular type of corrective support should assess individual models carefully rather than assuming that a stable trail platform provides the same function. A secure shoe for uneven ground is not necessarily a substitute for footwear designed to address specific stability requirements.
Does NNormal Make Carbon Plated Running Shoes?
NNormal's current running collection does not include a dedicated carbon plated racing shoe. The company has instead concentrated on lightweight construction, responsive cushioning and outsole traction.
This reflects the demands of technical trail running, where uneven surfaces and changing gradients can complicate the benefits associated with plated footwear. The effectiveness of any performance technology depends on how it interacts with the overall shoe construction.
Kjerag 02 is the brand's principal lightweight performance model, using responsive foam and a revised rocker geometry rather than a full length carbon plate. Its design focuses on providing an efficient running experience while retaining the characteristics required for technical terrain.
Carbon plates are increasingly found in specialist trail racing shoes from other manufacturers, although their benefits depend on the overall design and the terrain involved. They are not an essential feature of competitive mountain running footwear.
Does NNormal Make Road Running Shoes?
NNormal currently concentrates on trail and mountain running rather than producing a dedicated road running collection. Its footwear is developed primarily for natural surfaces, where traction and foot security are important considerations.
Some of its shoes can accommodate short sections of pavement or other firm surfaces, particularly when these form part of a route involving trails. However, their outsoles and overall construction are developed primarily for outdoor terrain.
Cadí is likely to be the most approachable option for runners whose routes combine smooth trails, gravel paths and occasional road sections. Its relatively moderate outsole makes it less specialised than the technical Kjerag models.
Runners completing most of their mileage on roads would generally be better served by footwear specifically designed for that purpose. Road running shoes typically use different outsole constructions and cushioning arrangements suited to repeated contact with firm, relatively uniform surfaces.
Which NNormal Running Shoes Should You Consider?
NNormal's current collection covers several different types of trail running, from faster technical racing to everyday outings on easier paths. The following models represent the principal options available in 2026, including waterproof alternatives for runners regularly encountering wet conditions.
NNormal Cadí
Introduced in 2026, the Cadí (pictured above) is designed for everyday trail running, offering an accommodating fit and generous cushioning. It features a supercritical foam midsole, cushioned ETPU footbed, 6 mm heel drop and Vibram Megagrip outsole with 4 mm lugs.
Its comfortable construction makes it suitable for woodland paths, gravel trails and rolling countryside. It is also an accessible option for runners making the transition from road running to trails.
NNormal Tomir 02
The Tomir 02 is designed for longer trail runs where cushioning, protection and durability are important. It features a supercritical EVA midsole, an 8 mm heel drop and a Vibram Megagrip Litebase outsole with 5 mm lugs. Reinforced construction and a secure upper provide additional support on uneven terrain. Its combination of comfort, traction and protection makes it suitable for mountain marathons, ultramarathons and extended training runs on technical trails.
NNormal Kjerag Brut
The Kjerag Brut (pictured below) is designed for muddy, wet and technically demanding terrain. Its Vibram Megagrip Litebase outsole features aggressive 6.5 mm lugs, while the Matryx Micro upper encourages water drainage. A neoprene tongue and close fitting collar help maintain foot security. With a 6 mm heel drop and lightweight construction, it is particularly suited to runners tackling soft ground, steep climbs and challenging mountain conditions.
NNormal Tomir 02 Gore-Tex
The Tomir 02 Gore-Tex combines the cushioning and protective construction of the standard Tomir 02 with a waterproof Gore-Tex Invisible Fit membrane. It retains the Vibram Megagrip outsole and secure fit intended for demanding mountain terrain. This version is particularly suitable for longer trail runs in wet and colder conditions. Runners who prioritise ventilation and water drainage may prefer the standard model.
NNormal Cadí Gore-Tex
The Cadí Gore-Tex is a waterproof version of NNormal's everyday trail running shoe. It combines a Gore-Tex Invisible Fit ePE membrane with a supercritical foam midsole, accommodating fit and Vibram Megagrip outsole featuring 4 mm lugs. With a 6 mm heel drop, it is designed for comfortable running on woodland paths, gravel trails and rolling countryside in wet conditions.
Are NNormal Running Shoes Good For Beginners?
NNormal has become more accessible to newer trail runners following the introduction of the Cadí. The brand's original collection was strongly associated with technical mountain running and high performance footwear, particularly through its connection with Kilian Jornet.
Although those models remain important, the current range now accommodates a wider variety of abilities and running environments. This gives runners more choice when selecting footwear for less demanding terrain.
Cadí provides the clearest starting point for beginners because it is designed around comfort, an accommodating fit and relatively straightforward terrain. Its cushioning and outsole make it suitable for runners exploring woodland paths, gravel routes and easier mountain trails.
Tomir 02 may also be appropriate for runners who expect to encounter more demanding terrain or are preparing for longer trail events. Its greater emphasis on protection can be useful when running conditions become more challenging.
There is no particular advantage in choosing the most technical or lightweight model when starting trail running. Comfort, suitable traction and a secure fit are more important than selecting footwear developed primarily for competitive mountain racing.
Are NNormal Running Shoes Sustainable?
Environmental responsibility has been part of NNormal's identity since the company was established. The brand places particular emphasis on durability, arguing that extending the useful life of footwear can help reduce the environmental impact associated with repeatedly manufacturing replacement products.
NNormal has supported this approach through durability testing, repair initiatives and greater transparency about the materials and manufacturing processes used in its products. The company has also sought to provide information about the environmental consequences of footwear production.
In June 2026, the company published its first Commitment Report, outlining its approach to product durability, repairability, recycling and environmental impact. The report also included carbon footprint information for much of its collection.
The company has conducted research into how long its running shoes remain usable. Its published studies have reported average lifespans exceeding 1,000 kilometres for Kjerag 02 and more than 800 kilometres for Tomir 02, based on data collected from participating runners.
These figures should not be treated as guarantees for every pair. Shoe longevity depends on factors including terrain, running style, body weight, maintenance and the conditions in which footwear is used.
NNormal has also introduced repair and footwear collection initiatives intended to reduce waste. These programmes represent a more practical approach to sustainability than relying entirely on claims about individual recycled materials.
Nevertheless, producing running shoes still requires energy, raw materials and manufacturing processes with environmental consequences. NNormal's approach is best understood as an attempt to reduce those impacts rather than eliminate them.
Are NNormal Running Shoes Worth Trying?
NNormal is worth considering for runners who spend a significant proportion of their time on trails and want footwear developed specifically for outdoor terrain. Its combination of specialist design, established outsole technology and emphasis on durability provides an alternative to the much larger collections offered by established running shoe manufacturers.
The relatively small range makes it easier to identify models developed for particular running requirements. However, runners who primarily use roads, require conventional stability footwear or want an extensive choice of cushioning systems will find more options elsewhere.
The brand's strongest appeal remains its specialist understanding of trail running and the demands placed on footwear in natural environments. Its focused approach may particularly appeal to runners who prefer choosing from a smaller number of clearly differentiated models.
Final Thoughts On NNormal Running Shoes
NNormal has established a distinctive position in trail running footwear in a relatively short period. Its partnership between Camper and Kilian Jornet combines established footwear manufacturing experience with specialist mountain running knowledge, giving the brand a clear identity within the outdoor market.
The company has developed a focused collection that accommodates different types of trail running without attempting to compete across every category of footwear. Its use of responsive cushioning, specialist outsole compounds and durable upper materials reflects the demands of running in natural environments.
The introduction of Cadí has broadened the brand's appeal beyond experienced mountain runners, while waterproof options provide additional choices for those regularly encountering wet conditions. This makes the collection more accessible without losing its specialist character.
NNormal's emphasis on durability and repairability is another important part of its identity. Although no running shoe is without environmental impact, extending product life is a worthwhile consideration when choosing footwear.
Ultimately, the most suitable NNormal shoe depends on the terrain you regularly encounter, the distances you run and the fit that works best for your feet. Comfort and a secure fit should remain central to that decision, regardless of the technology included in the shoe.
