This shoe was a huge disappointment.  I wear Rykas exclusively for teaching my Zumba and interval training classes.  My previous fave was the Studio D Mid, but it has been discontinued.  I had high hopes for this shoe as a replacement, but it was obvious from the hard sole and lack of arch support when I put the first shoe on that it was not going to work for me.  It was so bad I didn't even put the second shoe on.  Thank goodness for free returns!  :-)
