"I have high arches and am only comfortable in shoes that have quite a bit of arch support. I ordered these because I have several others pairs of Kalso Earth sandals. These fit relatively true to size. I find them a little bit wider than some of my others, but not enough that they don't fit. They do provide good support and are comfortable for a long day on my feet. My one complaint is that the sueded footbed is a little slippery. I feel like my feet slide around a bit due to that, plus the extra room. Once the footbed is worn out a bed, I don't think it'll be an issue."
"I've tried a ton of different brands (Asics, Mizuno, other Brooks shoes) and have ended up with these as my favorite. They have a nice, wide toe box, and are lightweight, yet still protective. I wear a size 6 shoe, size 7 in most running shoes, and 7 in these."
