I already own a pair of fitflop sandals and a pair of these boots in the tan color and I absolutely love them, so I just ordered the boot in black.  I wear nothing but comfort shoes, but these are my fav's.  One of my co-workers calls them my "uniform" I wear them so often!  Now, you have to understand that I have well in excess of 100 pairs of shoes so it's not like I don't have choices, but I choose these at least 3 days a week because my feet are in heaven when I wear them.  If I have shopping to do or any kind of running around after work, I won't even consider another pair.  I ordered my normal size and the boot is roomy, but that feels good.  If you prefer your shoes on the tighter side, might want to try a size down.
