Super comfortable and the heart section is transparent!
Easy to walk in and the width would be good for narrow to average feet.
I am usually an 8.5 and got a 9. I think there is just enough room that my feet won't get blisters and walk comfortably with thicker socks. I would size up.
Rated 0 on a scale of minus 2 to 2, where minus 2 is Runs Small, 0 is True to Size and 2 is Runs Big
