I bought these shoes 6 months ago for Zumba class.  I have several pairs of shoes for Zumba so these have not been worn that much.  The toe box was a quite roomy compared to my other Ryka shoes but other than that they performed satisfactorily for that activity.  Unfortunately the tongue of one shoe came completely unstitched.  I have never had this happen with any of my other shoes. I do not recommend this shoe because of this issue and I feel that this style has a completely different fit from other Ryka shoes.  I have since bought Ryka walking shoes and the fit is so much better than the Ryka Exertion.  These shoes should last longer than 6 months!  I am very disappointed.
