NNormal

Plenty of outdoor brands talk a good game on sustainability, then sell you a shoe that's falling apart by the end of the season. NNormal took the opposite view: the most sustainable kit is simply the kit that lasts longest. That conviction sits at the heart of a partnership between trail-running legend Kilian Jornet and Camper, the family-owned Spanish footwear house, and even the name gives away its roots – Nor-way plus Mal-lorca, because everything is designed in Mallorca and tested in Norway. And this isn't just a claim. NNormal have gone and tested their durability for real, and these things will take you miles. Around 840 of them, in the case of the Kjerag.

The credentials stack up elsewhere, too. NNormal is a certified B Corp, a member of 1% for the Planet, and a partner of the Kilian Jornet Foundation, which works to protect the mountain environments the rest of us love to run, hike and walk through. Timeless, functional, honestly built, this is the kind of gear you buy once and wear until the soles finally give out. Which, going by their own numbers, takes some doing.
