NNormal publishes a study with 7,000 runners proving that Tomir 02's average lifespan is 823km

NNormal reinforces its commitment to durability and repairability

IESE University validates the study and its methodology

NNormal, the sports equipment brand founded by Kilian Jornet and Camper in 2022, publishes a study of an investigation related to its bestseller, Tomir 02 shoe.

Following one of its core values, durability, the brand has developed a particular study, which concludes that the Tomir 02 lasts more than 800 km.

Over 7,000 runners, representing many different types of athletes, have been involved in the analysis, with an average result of 823 km under standard trail conditions. This distance is calculated for runners weighing between 65 kg and 80 kg on moderate trail terrain.

The evaluation assesses, in five different layers, the wear of the outsole, midsole and the upper, ensuring good levels of grip, cushioning and holding respectively.

“We will use this data as a benchmark to improve the durability of the Tomir’s franchise, as we did previously with the Kjerag 01. We are focused on extending the life of our gear, and we are investing lots of effort to reach this goal”, explains Sito Luis Salas, CEO of NNormal

In addition, Spanish IESE Business School has closely followed this exploration, validating the calculating methodology, which includes terrain and weight variables.

Durable and repairable

Every extra kilometer in a Tomir 02 means fewer discarded shoes, lower consumption, and a lighter environmental footprint.

Through the Lifetime Repair Guarantee, NNormal offers free minor repairs on all their shoes, handled by expert local cobblers in the Vibram-certified network. Plus, the Vibram Resoling Program extends the life of well-worn shoes with Vibram’s high-performance Zegalite rubber.

Always learning 

As a young, ambitious, and committed company, NNormal leverages these studies to continue improving its products. Beyond this exploration with the Tomir 02, last year work was also carried out on the durability analysis of the Kjerag 01.

Understanding that durability is essential to reduce the environmental footprint is the first step to get less consumption and lower emissions are needed in the trail running industry.
