It took me some fiddling to get the adjustments right but once I did they wore effortlessly. Comfortable, minimal, grippy.
Best pair of sandals. Works in most situations, urban, off road, jungle etc. Done 20km in them once. No issues. Wore it daily for a year. Soles on the heel were worn out thin due to heavy mileage on them. Thus second pair.
I've just received and fitted my Cairn sandals, and while I'm sure they're going to give me lots of happy hours outdoors, I would have liked to see a bit more space for wide and high volume feet. It would fit a little better if the sole was a bit wider around the midfoot. And the sandals only just fit me with all the straps on their maximum leniency.
This is my second pair. Usually wear 10.5 men's shoes. Last year I bought the 11 upon reading the recommendations; this year I bought the 10 and they fit much better. Wish there wad a wide option though be a use I'm almost hanging over the side on both pairs. Looking forward to getting out in the trails again when it warms up!
I've been trekking, hitchhiking, sailing, and overall dirtbagging around the world for the last five years. Minimalist footwear which can do it all has been searched and tested for a while now. A sandal that is tough enough to withstand the salt and sun of the ocean, reliable enough for high-altitude via-ferrata without gear, and designed smart enough for long-distance running and trekking... not an easy sandal to find. The (yes) entire Alta Via 2. Approaches for pic multi-pitches. Countless bushwhacking adventures in the Alps. Mountain summits. Extended time living in the Utah desert (including scrambles, swell explorations, etc.). These bad boys have yet to fail me once, and show no signs of wear save for normal sole degradation. Buy these sandals. Don't waste your time with other brands. The truth always reveals itself, and the truth is that these will outperform any sandal you are likely to find.
