I already own a pair of Mion sandals which cover the heel. This pair is open in the back like Crocs only these look way cooler. I'm a teacher and I wear them almost every day. My "cool rating" has gone way up with my kids, and they want to know where they can get them! I wear them when I get out of the shower; I wear them around the house and outside washing the car or puttering around in the garden; I wear them when I travel because they are a breeze to take off when I go through the X-ray machines at the airport. When winter comes, I will wear thick/thermal socks and continue to slip these babies right on! My only issue is with the arch support: I could use a bit more, but that's just me. They're still very comfortable when I want to rejuvinate them, I just drop them in the washer and let them air dry. Those of you who like Keens and other closed toe sandals will love these shoes!
