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.

    So far, so good!

    I think I am still going through a break in process with my Cairn 3D’s, still fiddling with adjustments, but love the sandals, the ‘low profile’ of them compared to others.

    2 pairs and love them!

    Recently, I bought a couple pairs of Bedrocks for my wife and I!! These sandals are amazing! My wife has a normal foot with high arches. I have a flat narrow foot. With the ability to adjust these sandals in so many different ways, we are both able to wear them exactly the way our feet need! I highly recommend these to folks with all kinds of foot shapes, widths, etc! The delivery was fast and both pairs of sandals came boxed up in great condition! Hell, they even throw in a couple of stickers as well! Thank you, Bedrock!

    Love my Bedrocks!

    These are the best outdoor sandals I have ever owned, and I have had them all! Teva, Chaco, Xero’s - you name it. These bedrocks are made to withstand anything, are so well engineered and are very comfortable. The thong between the toes takes a bit of getting used to, but once they are broken in- they are the best sandals you will ever slip onto your feet, staying put and feeling like they are a part of your body. I will never go back to any other brand after these. Thank you, Bedrock- I hope you can bring some more stock in- I know it’s difficult during COVID; but I would like another color! Size UP! I Am usually a women’s 9, and bought the 10 and they are perfect. Use the print out foot print that BR supplies online!

    My sandals arrived earlier than expected, which is always nice, so I decided to break them in on a short hike that afternoon. That hike ended up being less casual than expected, and I ended up putting 12+ miles in over the following 24 hours. Didn't get a single blister, and my feet felt great the whole way. I don't recommend doing this, but in case you do, Bedrock has you covered.

    Got one for myself and one for my wife, we love it the moment we put it on for the first time. It's our first pair and we've been looking for adventure sandals for a long time now. It's comfortable, looks good, we're definitely looking forward to take it out for some walks!
