In its two-year existence, the model NNormal has put its values on the desk. A type of core values is sustainability. In that vein, for one of many first instances we are able to recall within the working trade, the corporate shared the outcomes of an inside examine of the possible lifespan of its shoe based mostly on real-world testing.
The straightforward questions the examine asks are: What number of kilometers can an individual count on NNormal footwear to final? And, because of this, how does that have an effect on the environmental affect of 1’s trainers?
The model’s assertion is that firms are too centered on the CO2 consumption of a shoe individually when it’s truly the CO2 financial savings by merely consuming — thereby producing — fewer footwear that’s extra impactful. To this finish, NNormal promised to maintain affect minimization on the forefront and to make its targets and progress identified alongside the best way.

Like driving a Toyota Corolla for 300,000 miles, it may be a degree of delight to see what number of miles one can eke out of their trainers earlier than retiring them. For many of us, we merely need to get as a lot as we are able to out of a pair of footwear earlier than efficiency or integrity is misplaced, particularly when their value is all the time rising. Moreover, as we develop a higher understanding of the environmental affect of our path working pastime, many people need to make our personal working extra sustainable.
In early February 2024, NNormal launched a sturdiness or lifespan examine, the primary formal inside overview it has made public. The topic shoe was the model’s debut, the Kjerag — see our NNormal Kjerag overview — which founder Kilian Jornet famously raced a complete season in a single pair, together with wins at Sierre-Zinal, the Hardrock 100, and UTMB.
Although its public report doesn’t presently reveal components like whether or not the 511 testers had been compensated or offered footwear free of charge — to not point out some intangibles like had been they extra more likely to report positively/much less negatively based mostly on being a fan of the model — the examine says that the runners’ weight, the kind of terrain they run, and sure factors of emphasis alongside a sturdiness scale had been all included.
The sturdiness scale within the picture above represents phases of 25, 256, 756, and 1,100 kilometers. Quick time period points like minor toe delamination (round 25 kilometers) to long-term harm to midsole foam (round 756 kilometers) are represented alongside the timeline.
The graph beneath plots shoe end-of-life distribution for testers, with a majority of testers (70.45%) getting 800 to 1400 kilometers out of their take a look at footwear — that’s roughly 500 to 870 miles.

So what does a NNormal buyer do with their footwear when the helpful lifespan has expired? The corporate presents a few choices together with its No Hint program to let runners ship again their footwear for restore or recycle. In Europe, clients can find a cobbler to have footwear resoled by a accomplice educated to restore or exchange Vibram outsoles (the Kjerag makes use of Vibram’s Megagrip rubber) in addition to different materials failures.
Whereas among the sturdiness survey’s biases are unclear, NNormal is a minimum of taking the admirable steps of speaking concretely in regards to the sturdiness of its flagship product on a public stage along with selecting supplies – reminiscent of Matryx uppers and a extra sturdy midsole materials within the Kjerag – for its footwear with product lifespan in thoughts. The model can also be presently learning the sturdiness of its different major mannequin, the Tomir, in the same method.
Sooner or later, it might be nice to see a standardized protocol developed in order that different manufacturers might publicly share knowledge on their footwear’ sturdiness and, ultimately, giant scale external-to–manufacturers testing that an impartial group collects, aggregates, and shares. Seeing robustly sourced common shoe lifespan, cost-per-mile, and resource-per-mile metrics would permit customers to make higher knowledgeable decisions and, fairly probably, affect product designers, manufacturers, and the trade at giant to think about product sturdiness extra strongly.
One can dream. For now, kudos to NNormal for taking a primary step.
