Like these Reef Smoothy's. Like them, heck, I love them! This is my 2nd pair, many years since the first one, and the satisfaction is very high, as before.  Not sure how they manage to make flip-flops feel so much better than any other.  As for other reviewers, I ordered up in size (being a 10 or 10.5, I ordered the 11). The fit was just right.  Hope they keep making these products, it's obvious that I'm not the only one that thinks they are special.  Even Reef's many other models don't get the same level of positive ratings.  Would have preferred a color other than black, but the positives of fit and comfort more than compensate for that.
