Cairn 3D Adventure Sandals

Fast + Free US Shipping

The lovechild of Freedom and Support, Cairn 3D features our most advanced footbed to date. From our award-winning Cairn design, we’ve added a sculpted footbed that is secure, lightweight, and loaded for the long haul.

Vibram® XS Trek Regolith Outsole: Lightweight, long-lasting, and re-soulable.

Our most durable Vibram® outsole compound, best for grip in Dry conditions. For more performance grip in wet + slippery terrain consider the Cairn Pro lineup.

Equipped for Adventure

Our Patent-Pending design features premium webbing, 3 adjustment zones, and our sole-hugger wings for locked-in stability.

Premium Quality: We spent years sourcing the best materials in the world, so you can spend maximum time enjoying the outdoors. The Cairn is USA Assembled of Domestic and Foreign Parts.

1% For the Planet: We proudly donate 1% of your purchase to environmental non-profits.

Follow these instructions to take care of your Bedrocks and maximize their life-span:

For footbed's sake, do not leave your sandals in extreme heat (e.g. hot car) or intense direct sun exposure for durations ( e.g. sunny porch). Our ultralight Go Far Vibram® footbeds can warp if left exposed in these environments.

To clean your Bedrocks, handwash with a brush, water, and your favorite eco-friendly soap! Let them dry in a shaded environment or briefly in the sun. Do not machine wash.

To keep your Velcro® heel-strap long lasting, use side buckle adjustment for every-day in and out, and occasionally remove grit and debris from heel-strap by scrubbing with a wire brush.

    These felt loose until I realized, they are meant to feel like you’re not actually wearing shoes, and the ground is magically really comfortable. They aren’t loose or floppy at all. My feet are so happy!

    Posterior Tibial tendinitis

    After wearing them for two days I woke the third not being able to walk on my left foot due to posterior tibial tendinitis. Sending them back.

    This is a very atypical experience, we are reaching out to see if a different adjustment, different size, or different style footbed might work better for you.

    The quality is excellent. I'm having to get used to the the toe strap. The sewing holding it together rubbed on my foot and made it bleed. I've adjusted the clip, so the strap is in a different position. I'll see how it goes. It's a matter of breaking in no doubt. I guess the sewing might be more seamless. My foot isn't quite centered, the sandal might be a touch wide. I thought having the straps tight would close in the side supports. This is not the case. I'm a little worried my heel will wear in off center and speed up wear on the sole on one side. I had a pair of Luna sandals this happened to. One sided wear, and then your foot is always offset. Otherwise, I like them. They are also much lighter than the Lunas. Nice!

    For as long as the seasons allow here in Minnesota, the Bedrock Cairn 3D Adventures are my go-to footwear. When the temps get cool, you bet I’m That Guy with socks and sandals. Whether I’m walking around the city, through the woods, on the bike, or in headed downstream in the packraft, these sandals don’t disappoint. Comfortable, resilient, & versatile! Everything footwear should be.
