Cairn 3D PRO II Adventure Sandals

Fast + Free US Shipping

For wet and slippery missions, there’s Cairn 3D Pro II, the ultimate adventure sandal outfitted with our new Hook-heel strap, extra-sticky Vibram® Megagrip outsole, and molded 3D footbed. The Pro II G-hook and loop system locks in the heel strap like it does the front, for a super secure fit that won’t fail in the frothiest rapids or thickest silt.  

Cairn 3D Pro II Features

New G-hook-and-loop heel and front strap system creates an extra secure foothold that won’t gum up in mud or pull off in whitewater. 


3D footbed is zero-drop anatomically molded with tasteful arch and toe support. Built for those seeking extra support or looking to log big miles.


Vibram® Megagrip Sole in non-marking grey Andesite is super grippy and designed to perform in wet + slippery conditions. Re-soulable.

Equipped for Adventure

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

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.

    So far so good.

    I have been wearing them around the house. So far I love them. Summer is coming. I will put them thro a class V test then. They will see multiple rivers and trails in the near future.

    Love these sandals!

    These sandals are awesome!! I bought them before a Costa Rica trip, wearing them a couple times around. I wore them hiking, walking up and down rivers and was pleasantly surprised at how grippy they were on slippery rocks and roots and how secure my foot felt in them. They didn’t need a “break in” period like some sandals require and they immediately felt comfortable and not claustrophobic on my feet. Super easy to adjust when needed. I usually wear a women’s size 10, and I purchased a size 11 on the advice of a friend and they fit perfectly. Super happy with my purchase!

    If I had to chose only one pair of shoes to wear for the rest of my life, it would be the Cairn Pro II

    These sandals are amazing. I just recently upgraded from the original Cairn sandals to the Cairn Pro II, and I love them. I wore my original Cairn sandals for over 2 years on many adventures and they never failed me. Iove these things to death. They really are the ultimate sandals. I've done some serious mountain hiking in both the Rocky Mountains and the Andes with these bad boys and they've handled absolutely everything I've thrown at them. I also just love wearing them as every day shoes and will casually walk around town with them. I'm planning on doing some traveling in the near future and these are the only shoes I'm bringing with me. I think the strongest statement I can make about these sandals is the title of the review. If I had to chose only one pair of shoes to wear for the rest of my life, it would be the Cairn Adventure Sandals. 5 Stars!!!

    Pro II Sandals

    Great sandals! Your product does exactly what your website describes, including what the reviews describe as well. So far, just wairing them around the house and running errands. They feel sturdy and comfortable. The Vibrum soul is a bit stiff, but that’s to be expected for break end. I’m pleased with the purchase.
