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.

    Premium Quality 

    • We spent years sourcing the best materials, so you can spend maximum time enjoying the outdoors. With exclusive Vibram® rubber soling, polyester and nylon webbing upper, metal and acetal plastic hardware, and US military-grade Velcro®, you’ll do just that.
    • Average weight 10.5 Oz per size 9 sandal

    Perfect Sandals

    I've been looking for the perfect sandals and Bedrock has come through! They are super comfortable being more like a barefoot shoe, while also very performance oriented with the super grippy sole. Was worried about the toe strap but I wore these sandals a whole camping weekend and they didn't rub or bother at all. Recommend these highly!

    Im not a sandal person, ever, but a friend bought these for hiking and after looking into reviews. I honestly wear them all the time that im not working (close toed shoes) and really enjoy them. They work great in all circumstances! The only downside is my wife hates sandals on men, but the counseling is helping with that.

    The Bomb.

    Background: I have worn Chaco Sandals since their inception when they were Gecko Sandals. I was first turned on to them by a Colorado River Guide. Those originals with the five Tennie grip were awesome, but Chaco like Teva slowly slipped into the Corporate don't give a %$&* about customer feedback category. Essentially I became annoyed by their lack of wet water grip on rocks. I started searching the web for sandals with true wet water grip and found Bedrock! Again, Colorado River Guides were ranting and raving about them, so I bit the bullet and bought a pair. After an entire Summer river rafting in them I can tell you they are like no other sandal I've ever owned. They are AWESOME! Sure, they look a little funny, but the support, and the wet water grip are amazing for a single toe sling. Absolutely equal to a full strap sandal but without all the stone collecting, long dry time and stink. The other supreme bonus is the single quickdraw buckle on and off which is super easy. Do yourself a favor and hit the buy button. You won't regret it!

    I love these sandals

    I was looking for something more than a ‘flip flop’ and less than the overbuilt, goofy looking Tevas and Chacos. I stumbled across Bedrock’s name and am so glad I did. I visited their factory store in Richmond - spoiler alert it’s in kind of a weird part of town - and Kendra took excellent care of me in the store. I’ve worn them pretty much nonstop for 3 weeks and have found my comfort zone with the adjustments so that they now feel super comfortable and stable. TL;DR they’re awesome. Buy some. They’re rad.
