Versatile inside/outside trainers that thrive both on the trail and in the urban jungle. From work, subway, bar, or gym, to rucking, the challenge, hiking, and travel.
Developing the I/O Cross Trainers
I’ve lived in some version of these for 18 months. We tested the I/O’s on concrete, trails, inside the gym and outside in every season with the gym on our backs. We’ve traveled all over the world in the same pair of shoes, been on our feet all day every day for long distances and long stretches of time, then done it again the next day feeling good. Every new prototype was an opportunity to adjust a millimeter here, a millimeter there, until they were just right and ready for our kind of daily lives, which means they have to be ready for anything when you are.
Places they've been tested: concrete, trails, the beach, muddy obstacle course (Savage Race), technical obstacle course (Fort Carson), the gym, the bar (OK, plural, bars), biking to work every day, long flights, short flights, train rides and lots and lots of adventures on foot, the 26.2 Star Course in San Francisco, always taking the stairs, summer, fall, winter and spring, hot and humid, cold and dry.
These trainers are my new go-to gym shoes — even for lifting. They’ve got all the support (and I mean ALL the support) you need to wear all day, every day.
The I/O is a true multi-purpose shoe — great for travel (getting to and wandering around a city) — and just as great for training (rucking or hitting the gym). This shoe really does it all, and does it well.
Support. Support. Support.
The I/O Cross Trainers are proudly NOT minimal, they're NOT runners and they're NOT sneakers. They are ruck trainers with tons of support.
Support that manifests under weight and when moving weight.
