These are by far, the best flip flops I have ever owned. They are phenomenally comfortable! Very light, and durable. I have been wearing them daily for almost six months, and they have quickly become my favorite! The sandal, as it's name implies feels very smooth and soft, the straps do not chaff between the toes, and do not feel constricting, or abrasive in any way. They are easy to keep clean.

Yes, they do run a bit small, and a little narrow if you have wide feet, but it's not to the point where your foot will come into contact with the ground, and it does not look bad.

In my opinion, they are more comfortable than the Reef Contour Smoothy, and the Havaianas Top sandal.

UPDATE 7/14/13

I bought another pair (4th Smoothy, Grey/Black) and it seems like the newer sandals are 3-4mm shorter than my older sandals, and are now made of a much harder compound. They are also more slick on the soles. I still like them, they still fit me with a little overhang (1-2mm)at the back while putting pressure on my feet. The straps are much tighter. I actually had to use my fingers to get the new ones on. I liked the snug fit of the Smoothy, I just hope this one breaks in to the level of comfort as my first 2 pairs. I'm not taking any stars off... yet...
