I was looking at these shoes for a while having owned a few pairs of Asics but read some reviews that were not favorable, and chose to buy Ryka Studio D based on good reviews for those. Well I should have gone with my first impression and bought the Asics first. they are great Zumba shoes and every Asics I have ever owned has fit me perfectly and felt broken in from day one.  I need a wider toe box and Asics seems to make all of their shoes with a wider toebox and they fit perfectly. Spins, jumps and slides felt controlled and the gel seemed to absorb  a lot of the shocks. Way better looking, fitting and performing shoe than the Rykas which ran large and seemd to have no arch support or any "shape" to them. If you have worn Asics before and liked them, I think you would love these shoes for Zumba.
