I discovered orthaheel tide sandals over the summer and really loved the way I could wear them all day and not have foot pain.  I decided to try these out because now that the weather's colder I need to wear a proper shoe, plus they were sale priced.  I like them because even though they are slip ons, the multiple elastic bands stretch to make the shoe form fitting.  Also I experience foot pain on my left side and these help alleviate it because they have a great orthotic insert with proper arch support that takes getting used to, but once you do it feels really good.  My only complaint is that I have experienced some heel rubbing, especially on the left foot.  Wearing thicker socks helps.
