Low Top Ruck Trainers for Inside/Outside

Inspired by old school cross trainers with added support for your feet over all the miles. They're also versatile so that you can do the work inside and outside of the gym.

Features

Challenge Leather™ & CORDURA® Upper
Uppers are constructed from breathable 1000D CORDURA® utilizing polyester (instead of nylon used in our Rucksacks) for more flexibility to contour to your foot. New full-grain military spec Challenge Leather™ on the toe cap, eyestay and heel tab is designed to minimize scars and scuffs. 2” knit webbing across the midfoot adds stability and a padded tongue provides comfort and protection against lace bite.

Premium Suede Heel Counter
Wraps inside, around a supportive, injection molded plastic heel counter. This combo stabilizes your heel as the suede leather prevents the kind of friction that causes hotspots and blisters.

Wide Toe Box
Generous forefoot area lets your toes breathe. Over time and distance during any activity including rucking or traveling, your feet will swell. This extra space reduces the friction that can occur if your feet rub against the insides of your shoe.

Custom Compression Insert
The I/O Cross Trainer’s insert is not your normal worthless, flat, cheap single foam insole. Our custom insert uses a dense compression foam system that supports your entire foot from heel to toe - including contoured arch support - throughout the duration of your foot strike.

Shielding Drain Hole
Keep sand and debris out and expel water with old fashioned technology that just works - with every step, you push the water out the side of the shoe.

Midfoot Webbing
2" engineered knit webbing for additional midfoot stability. Not just a fashion statement, the signature webbing along the side helps keep your foot stable during quick movements and on uneven ground.

Supportive Heel-to-Toe Drop
Classic powerlifting shoes have a 20mm+ heel-to-toe drop (and meant for nothing else), running shoes are all over the place (according to the latest fad), Chuck T's are zero drop (and painful over all the miles). Our shoes are 10mm so you have the mobility you need for high performance training with enough millimeters to keep you fully supported while rucking.

Compression Molded EVA Midsole
The lightweight compression molded midsole provides the cushion and support you need without weighing you down. Saving ounces here also means we can use a more versatile rubber outsole and the most durable upper materials available.

Dual Compound Rubber Outsole
New dual compound rubber outsole adds traction and durability with understated protection at the toes of the shoe for when you're rucking in rocky terrain or doing push-ups. Forefoot rubber is formulated for increased grip while the heel area is formulated for abrasion resistance and longevity.

No Spacer Mesh
Spacer mesh is soft, squishy, and feels comfortable to your hand when you touch it. But it’s a trap, literally. The first time spacer mesh looks at any kind of water, your shoes get heavier and they stay that way. So we use neoprene that doesn’t absorb and doesn’t stink.

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.

Jason McCarthy, GORUCK Founder

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.

Ricky V, GORUCK Cadre, Army Special Forces

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.

Richard Rice, 5th Special Forces Group, US Army 1966-94

Support. Support. Support.

Ruck Trainers

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.
