I am not sorry I bought these in the least.  They are VERY comfortable.  They are true to size.  I wear a 7 and bought a 7.  I could have used a 7.5 because my heel is right at the back of the sandal but it does not look odd at all.  The 7.5 probably would have been too big.  I don't feel a whole lot of "workout" with these like I do with the Skeckers shape-ups but I love them.  I'm gonna buy more for the sheer comfort.
