I mostly wear Reefs, but someone recommended the Sanuks with the yoga mat bottoms, which seem to be all the rage these days.  These fit reasonably well and sizing seems normal, perhaps just a bit shorter in length than expected.  They are definitely cute and stylish.  I can see them working well with most casual, summer outfits.  They feel good on my feet when I first put them on, but I'm not convinced they will offer the same support my Reef Cushions do, for all day wear.  We shall see.

Update:  I really wanted to like these, but after giving them a try, its clear they are just not right for me.  Though soft & swishy, they offer zero support!  After a short time of wear, my feet and ankles were killing me.  I had to pull them off and put back on an old pair of my Reefs.  Like magic, the pain and discomfort went away!  To be fair, I do have problem feet.  I have bone overgrowth in my ankles.  Just because they didn't work out for me, doesnt mean they won't work for someone else.  Just know you may want to pass on them, esp if you need support or have certain conditions.
