I bought these to wear at Jazzercise.  I have always worn Rykas in the same size, but this shoe seemed a bit shorter than others I've worn.  The main problem I had was that the toe box was too wide for my foot, so I felt like my foot was sliding around even though the laces were tight.  I have narrow feet so maybe a person with a wider foot would like them.  Unfortunately I returned them because I didn't feel like my foot was getting the lateral support I needed for aerobic dancing.  I have worn Ryka Enhance and Influence before, so I may go back to those.
