I've been doing Zumba and Tae Bo.  I have problems with pain in my arches and overpronation.  I had high hopes for these shoes based on the reviews.  The shoes were too tight.  I would say they run narrow.  I wear a size 8 and have a high in-step.  Once I put the shoes on, tying them was uncomfortable ant that velco strap that crosses the metatarsal area?  Forget about it!  Unfortunately, they are going back.
