I own a similar pair that I purchased from Kohl's.  I think these look better than the one I bought.  They are very comfortable.  It feels like I'm walking on air cushions.  It wore them to my cardio sculpt class and they added another dimension to my workout.  The subtle rocking caused by the shoes made my core work just that much more to stabilize me while I'm doing squats or leg lunges.  When I saw these on the Lightning Deals, I purchased a pair for my husband.  He has narrow feet so these were perfect.  After wearing them just a day, he said his calves are sore.  Wish I had purchased a spare pair for myself.
