I bought these sandals as a summer alternative to the sneakers I wear when walking long distances. These sandals adjust with velcro at three points, making them very stable on the foot. They have a very soft inner sole that molds to the shape of the foot after a few days of use, and a super non-slip rubber sole on the outside. I have used them on dirt trails and rocky beaches and had no issues.

Personally, I found them very comfortable and relieving after many hours of hiking/standing, but I give them 4 stars because they are slightly heavier than other similar sandals.

By the way, their color is more towards khaki, not completely gray.

Their size is as expected, and as for the width of your foot, you can adjust it with the velcro they have.
