This shoe caused me foot pain even when I put in some expensive inserts.  Wearing these shoes caused me pain in my heel, arches and legs.  I have been taking Zumba classes for six weeks now and have been using New Balance cross trainers and did not have foot problems or leg problems.  I wanted a lighter shoe that would slide easily.  I cannot believe how this shoe is getting high rating.  I am returning this shoe for a refund.
