I was looking for sandals and didn't want to mess with straps or ties. These are great. I did have a very short break-in time (3 days) before I could wear them all day. The balls of my feet were a little tender after walking on very uneven ground at an air show. I should have known not to wear them there! By the third day I could wear them all day with no issues! There is an adjustment available on the straps with velcro if they are a touch too loose but I have not used it.
