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 Pro Custom Sole: Ultra Grippy, Comfortable, and Durable

  • All Cairn Pro Sandals are made with 100% vegan materials and construction.
  • NEW plug-less toe post and aluminum hardware for next-level durability.
  • Ultra-grippy, exclusive REGOLITH Bedrock x Vibram® outsole made Megagrip. Aggressive, angular lugs massively increase performance and durability, while shedding mud and debris.
  • Granite Grip footbed features grooved, triangular traction, that provides excellent grip in both dry and wet conditions.
  • At 14mm stack height, the Cairn Vibram® sole is just the right thickness - not too thin, for extra rock protection and increased durability, and not too thick, for maximum flexibility and weight/space savings. 

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.

    Great for desert sand!

    These sandals just feel so good on my feet! I hike and run the desert sands near El Paso and the Pro 2s are awesome. The hook system is really great for keeping them secure. I printed out the sizing template and followed the instructions closely and they fit perfectly. Obviously, i won't be wearing them to bushwhack (cactus and rattlesnakes!), but running on sandy desert roads in these sandals is wonderful!

    These are everything I hoped my Lunas would be. The fit and design is amazing. I wear a 9 Luna and a 10 Bedrock. Well worth the switch.

    Ready for the Trail

    I bought these sandals specifically for backpacking and hiking. I often hike barefooted but like to wear sandals on rocky/gravelly terrain and when the ground is cold. I had been making my own huaraches and they worked great as long as they were dry. Whenever the homemade sandals got wet, whether from rain or a little spring water crossing the trail, my feet would slip on the footbed. I do not have that problem with the Bedrocks. My foot stays securely in the sandal even when wet. Problem solved. Beyond that, the tread on the soles is better than anything I could buy. The piece that fits between the toes is comfortable and does not cause irritation even when wet. I love that there is no velcro. None. The soles are a little thicker than I am used to, but they are good for hiking on gravel and such and will last longer than thinner ones. I especially like that Bedrocks are made in the USA. I did have one small problem at first: the straps caused a little irritation on the tops of my feet. They were rather stiff. After I wore them around town and on a few short hikes and walks over about three weeks, they softened nicely. This past weekend, I wore them for 7.5 miles on the AT in GA with no problems whatsoever. Uphills, downhills, through the piles of leaves, over the wet rocks - my feet were stable and I had no blisters at the end of the day. Yay! Overall, I REALLY like my Bedrocks, and - as long as they hold up well - I will likely recommend them to all my friends. Thanks for a great product!
