My sister always wore clogs like these and I thought they looked clunky. Then I saw more and more people wearing them. Finally someone said, "get these if you take up boating, so the water can drain right out." So I got some, even though we don't have a boat yet.
I wear them around while gardening and park them by the back door when I come in. I don't have to worry about them getting wet.
They are incredibly cushy and comfortable for walking. I don't even feel the gravel underfoot as I walk to the mailbox. The toe area is roomy enough for my wide foot and that's always been a struggle to find extra wide shoes to fit. They don't slip around.
For me, the part that comes up over the arch of the foot could be cut a little more open. I have a high arch though, and it rubs a little there.
They really are lightweight, so you don't feel like a clodhopper in them. Convenient to slip on and I'm really glad I finally gave in and got a pair.
I have many other clogs, but they all feel stiff and not nearly as comfortable as these.  I end up only wearing my Sloggers.
