If you're a trail runner, there's a decent chance you have a pile of shoes in rotation. A light, bouncy pair for days you want to go fast, a more rugged design with deep lugs for muddy trails, and shoes that prioritize comfort when you want to go the distance. But wouldn't it be nice if you could have just one pair of shoes and switch out the midsole? That's a question that's clearly been on the minds of ultra runner Killian Jornet and the folks at Nnormal, who recently unveiled a shoe that does exactly that.
The innovative (to say the least) Nnormal Kboix 01 is what the brand calls "a multisport, modular shoe" that lets you choose your own adventure by swapping out different midsoles built for different types of run.
