Well, they are what they look like, canvas, and pretty casual. If I was a young dude, I'd wear them to the beach.
I was hoping for a bit more support, but I didn't get all that much, as its an open back, my heel was slipping back onto the edge of the shoe, odd, at its a 13 and I take a 12, so it should not have been too small.
They are ok, the shoe itself is pretty soft, without too much support. For a while, I put in my birkenstock insoles, that helped, but my Sole inserts did even better, but again, things might spill out the back.
all in all, not too bad. After a few months, they are already getting dirty, as they are canvas so not easy to just wipe off. I did spray them and wash them in the sink once, that might have helped a bit.
I don't think they will last more than a year of so, but they're slippers, so I guess that's to be expected.
