Vibram® XS Trek Regolith Outsole: Lightweight, long-lasting, and re-soulable.

Our most durable Vibram® outsole compound, best for grip in Dry conditions. For more performance grip in wet + slippery terrain consider the Cairn Pro lineup.

Equipped for Adventure

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

Premium Quality: We spent years sourcing the best materials in the world, so you can spend maximum time enjoying the outdoors. The Cairn is USA Assembled of Domestic and Foreign Parts.

1% For the Planet: We proudly donate 1% of your purchase to environmental non-profits.

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.

    Love them.

    I got them and put them directly on, nice and comfortable. Easy to adjust and took them directly to Mexico for walking on copper stones. Worked out

    Way to Hard

    I tried on at home and wore them for less then 30 minutes and decided they needed to go back. I’ve had 3 surgeries on my right foot and these were just way to hard and with no arch support.

    Best sandals

    Simply brilliant !! These sandals are everything they claim to be. Extremely comfortable, can be worn for a long period of time on across any terrain. Love them. Highly recommended for treks and long walks.

    A lot to like, but one major negative

    Love the weight, traction, look, strap design, etc. I do not love the cord thong. It gives me a sore spot between my toes. I think it is due to the lack of flexibility as there is no give and also how thin it is. I'm an avid flip flop wearer and used to thongs so it's not that. I think the thong should be rubberized or have some sort of bumper added around it to give it a little flex and/or cushion. I never have issues with thong flip flops that have the typical cloth thong. Those are wider and I think they do a better job of spreading the weight where the cord thong is thin and digs into the area between my toes.

    I’m not sure if I should have gotten a larger size. The right Sandler fits well and is comfortable, but the left foot is less so especially by the split between the big toe & second toe. I will continue to wear them but not on long outings at this point
