Love These, But They Needed Adjustment

I bought these shoes initially to take as camp/river crossing shoes on a trip to Iceland. They didn't make it in time, but I've since taken them hiking and they've proved fantastic for really hot hikes or trails with a lot of water. Very durable and extremely lightweight, which is great for backpacking. But they've actually become my go to dog walking/rainy day shoes for around the city. Very comfortable, great breathability, and the color/cutouts give them a really cool vibe. I also love that they're made sustainably and am excited to see a shoe company using really innovative materials.

I would note that the first day I wore these, I thought they were going back immediately. After backpacking for 56 miles in Iceland I came back without so much as a blister on my feet. Two hours of walking in these and my friend nicknamed them the carnivore shoes because I had multiple blisters and spots where the skin had been chafed raw. I liked them so much though, I gave them a second chance (after my feet had healed) and found my mistake was over tightening the laces the way I would on a typical athletic shoe. These should be worn looser because the material is pretty unforgiving, but not so loose they slide on the foot. I spent that dog walk stopping every couple minutes to tweak the fit, but once I got it dialed in, I was able to leave it at that fit. Now I wear them all the time, no issues. They've definitely become one of my favorite pairs.

The best

I didn’t think I would like these and I was very wrong. Very comfortable, and perfect for warmer rainy weather or any muddy adventures. They rinse off easily and don’t make my feet hot and sweaty like I was worried they might

Great Shoe

Great shoe for backpacking, light weight, durable, quick dry, and held up well when walking on rough terrain.
