I had recently had surgery and was having some problems with edema in my feet and legs.  I didn't know from day to day what size my feet would be, and I couldn't wear anything with laces or fasteners.  So I looked for some type of slippers that would have a good sole and that I could fasten - that's exactly what I found in the Utopia. These are comfortable and look ok with sweats or jeans - and best is the velcro closure that adjusted to my foot size.  There isn't much support in them - after all, they are slippers! - but you can wear them outside if you're not planning to go on a long trek.  Nice rounded toe shape, too, so if your feet are wide they will accomodate well.
