I dance Salsa and these were very comfortable.  The straps are a little on the long side, need more holes poked in the straps but still nice.  I like that they go under the shoe instead of just around the ankle.  They run true to size: my other dance shoes have been a full size under my street shoe size but when I ordered these like that, I had to return them as they were a bit too snug and the side of my big toe hung off the side.  The toe opening is more narrow than I am used to so I was concerned that my toe would drag the floor and cause a problem.  Once I got the corrected size this wasn't so much of a problem.
