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.

    The Cairn 3D PRO Custom Sole: Ultra Grippy and Adventure Capable

    • All Cairn 3D Pro Sandals are made with 100% vegan materials and construction.
    • Ultra-grippy, exclusive REGOLITH Bedrock x Vibram® sole made with Megagrip. 
    • Our new Geo-patterned footbed features macro pentagonal-grooves on the sole, providing excellent grip in both dry and wet conditions, and more aeration power to keep your feet less sweaty.
    • At 16 mm base stack height under the forefoot, the new molded Cairn 3D Vibram® sole is a union of freedom and support. 
    • Zero Drop from toe to heel.

    Strap System: No-Slip Secure Fit.

    • Bedrock Sole Hugger design cradles feet with side-to-side support, keeping you stable in challenging conditions. Patent Pending.
    • Intelligent 3/4inch wide strap system with three independent adjustment zones for quick, secure fitting. Patent Pending.

    I’ve been trying to find a sandal that I could do a simple 3 mile walk. And daily hikes. I did the walk in Tevas And thought this is much worse than when I wear my tennis shoes. Watching the videos on YouTube about the Sonos I thought wow these are probably going to be better . When you’re wearing AirPods and you walking in the sandals you could literally feel your bones smacking the ground . Good feel it and hear it all the way up your spine . I could not find a comfortable position to put the tongue part you kept rubbing on my toe and just hurting like crazy .

    Who know you could fall for a sandal?!

    I saw these on a guy in the subway and liked their look a lot, but I was afraid they wouldn’t be comfortable. I had tried to love Chacos as so many of my friends and family do, but they gave me blisters on the backside of my heel. After hours walking around Missoula, Seattle and Taipei over the last few weeks in these new Bedrocks, I haven’t had any discomfort—loving them!

    Not sure I’ve yet to have taken them off.

    My feet ain’t smellin the best. I should probably take these off and clean them. But I’ve worn them to a baseball game, the follow up shopping trip, the drive home, worked on my Jeep, built a deck, did yard work, and fender off hoards of women wildly attracted to these bad boys. Comfortable-Check. Stylish-yuuup. Durable-you betcha. These are good summer shoes!

    Great Hiking Sandals

    My girlfriend and I went hiking up at lake Elmore in VT, which had all different kinds of terrain. I was a little hesitant to wear sandals on a hike but my girlfriend convinced me that we would be fine in our Bedrock sandals. She couldn't have been more right! Not only did I feel completely comfortable the entire hike but I was also very confident with every step by the end of the hike. These sandals had better grip on the rocks than some of my more expensive hiking boots. We both were very pleased with our purchase and I am certain that we also convinced our friend that was on the hike with us to buy his own pair because of how much we were praising them!


    LOVED hiking in these!

    My boyfriend and I both have a pair of these sandals and we wore them for the first time on a hike with a friend and by the end of the hike we had our friend convinced to buy a pair! We both couldn't get over the grip these sandals had on the rocks and how confident we both felt going up and down the mountain!!!
