Our unique sizing is unisex and based on a Centimeter scale; our size 9/10 means that the sandal is roughly equivalent to size 9 for men, and size 10 for women. Some people find our sizes run slightly small especially in our smallest sizes. If you are deciding between two sizes we typically recommend ordering the larger one.

The Cairn Custom Sole: Ultra Grippy, Comfortable, and Durable

  • Ultra-grippy, exclusive REGOLITH Bedrock x Vibram® outsole. Aggressive, angular lugs massively increase performance and durability, while shedding mud and debris.

  • 8mm Go Far midsole that is more durable than EVA, yet light and springy.

  • Granite Grip footbed features grooved, triangular traction, that provides incredible grip in both dry and wet conditions, while simultaneously helping to aerate your feet.

  • 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.


Premium Quality 

  • We spent years sourcing the best materials, so you can spend maximum time enjoying the outdoors. With an exclusive Vibram® rubber outsole, polyester and nylon webbing upper, metal and acetal plastic hardware, and US military-grade Velcro®, you’ll do just that.

  • Made in the USA with US + Imported Components. Custom Vibram® Sole Imported.


  • 7.8 Oz per size 9 sandal.
