Is the NNormal Kjerag 02 good for ultrarunning?
Mostly. The NNormal Kjerag 02 suits ultrarunners who prioritise low weight, precise handling and speed on firm or mixed trails. Its 26/20 mm stack and 6 mm drop provide some comfort for distance, and one reviewer completed 36 km comfortably. It is less convincing in deep mud or for runners needing substantial cushioning.

What is the Kjerag 02?
The NNormal Kjerag 02 is a lightweight, low-stack trail shoe designed for fast running on technical and mixed terrain. Its listed figures are 26 mm at the heel, 20 mm at the forefoot and a 6 mm drop, with a single-layer Matryx Light Jacquard upper and supercritical TPEE/EExpure+ foam. Reviewers at Better Trail, Gritty Runners and Runnea UK praise its responsive feel and secure foothold. Published weights vary from 214 to 240 g depending on source and sizing. The Vibram Megagrip Litebase outsole has 3.5 mm lugs, and there is no rock plate.
How does it perform on ultras?
On trails, reviewers describe a springy, propulsive ride and precise handling, with dependable grip across most wet and dry surfaces. One reviewer reported running 36 km comfortably and considered the shoe suitable for training and racing. The NNormal Kjerag 02 offers more comfort over distance than a strictly minimalist shoe, but its cushioning and underfoot protection remain limited compared with more cushioned trail options. Testers note that the 3.5 mm lugs are less effective in deep mud or boggy ground, while the firm feel can become harsh on pavement and gravel.
Who should buy the Kjerag 02?
Choose the Kjerag 02 if you want a light, responsive shoe for fast training or racing on technical, mostly firm or mixed trails, and value ground feel over plush cushioning. Its secure upper and precise ride suit runners who are comfortable with a snug fit. Try it on first if you have wide or high-volume feet, as reviewers disagree about forefoot room. It is a less suitable choice for boggy routes, frequent hard-surface miles or anyone who needs substantial rock protection. Long-term durability of the single-layer upper is not yet clear from the available reviews.

Frequently asked questions
Does the NNormal Kjerag 02 fit true to size?
Fit opinions differ. Some reviewers find the toe box comfortable, while others describe a snug forefoot that may not suit wide or high-volume feet. If that describes your foot, try the shoe on before buying. The available review data does not establish a universal sizing adjustment.
Is the NNormal Kjerag 02 durable?
Reviewers praise its secure Matryx upper and Vibram outsole grip, but long-term durability of the single-layer upper remains uncertain in the available reports. The shoe has no rock plate, so it also provides limited underfoot protection. There is not enough evidence here to confirm its lifespan.
How does the Kjerag 02 compare with the original Kjerag?
The available reviews do not provide a direct, quantified comparison with the original Kjerag. They describe the Kjerag 02 as offering more cushioning and protection than a strictly minimalist shoe, while retaining a light, precise feel. Treat that as a description of its ride, not a measured comparison between models.
