I have own these sandal for a couple of year now . they may be a excellent dry-hiker sandal but they be not good in mixed environment . I have find that the sole of these sandal become a almost frictionless surface on moist rock , stair , etc. . I take a bad fall in a tidal pool in Costa Rica two year ago and almost lose it on some wet stair next to a swimming pool in Rio this year . I know , it take I some time to learn a lesson . thus , if you intend to get these for water\/boating shoe , you need to look for something with a Vibram sole or some soft material , not these !
