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.

    Fantastic sandals!

    I wear work boots 40-50 hours a week for work. I wear sandals 90% of the time I'm off work to keep my feet healthy. I live in Florida so that means all seasons. I've been using another name brand for years. I liked the freedom these appeared to offer so I ordered a pair. I am very pleased with the comfort of these sandals. I will make note that the size runs a little small for me. But I have a wide foot and high arches so i will order 1 size larger for my next pair. And i will be ordering many more pairs. I spend a lot of time outdoors with my hobbies and these sandals are perfect. Looking foward to ordering my next pair!

    Blown away

    Ran a 10k straight out of the box...on gravel. Smashed it, and I am not a light human. Really blown away.

    Hiking in sandals

    I bought these sandals because I needed a great hiking shoe for Hawaii (rocks and crossing streams). Bedrock came highly recommended by my husband, they work great for him. I had a really rough time with this sandal. The soles of my feet hurt and I had blisters on the top and sides of my feet. Wearing them was quite a process as far as having to put bandaids in all the painful areas. I don’t know that I’d buy bedrocks again :( maybe there is a very long adjustment/break-in period???
