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

    the sandal that locks your step like a cleat.

    I walk a great deal and prefer sandals down to 45°F. here in Harlem I have to often Sprint to catch a train, bob n weave thru crowds, pivot on a dime on wet tile floors, and avoid injuring myself or anyone else while doing so. the innovative design (3-point concentric adjustment, locking hardware, wide rubber heal posts, intelligent tread pattern, gummy sticky sole even when wet) and the heavy duty construction (high-grade webbing, thorough stitching, Kryptonian density, locked in paracord toepost insulated from ground contact, durable hardware) all combine to create my Dream Sandal, locking onto my feet, and locking my feet to the ground with sure, easy steps. depending on what you've been wearing recently, you may need to give your feet time for any "hotspots" to adjust, and for the sandals to break in. in other words, you may want to get these a few weeks BEFORE your big hiking trip. again, depending on what your last pair of go-to footwear was. I got them in the new burgundy color, and they look slammin'! their generous re-soling program means I'll be rocking these puppies for years to come, and I'm looking forward to it!

    Rugged as hell

    I can't destroy these no matter how hard I try and have worn them everyday since I've gotten them. They are fantastic. 10/10 would recommend to anyone who wants a rugged hiking sandal (p.s. WAY better than chacos. Sorry but not sorry because I've had both)

    Immediately my favorite sandal. Once you get the straps right, they fit perfect! So comfortable and not chunky looking like Teva’s or Chaco’s, which was a huge problem for me. Can’t wait to take them on all the adventures!

    My new go to footwear!!!

    I always hated the band that wraps over the top of my mid foot in Chacos. I decided to give these sandals a shot, and wasn’t disappointed. They’re lighter and more comfortable than Chacos, and their Vibram grippy sole is great for river time.
