At first the shoes seemed great.  I worn them in the house and they were very cushy and comfortable even though the shoe design was different.  I wore them outside and after just about 3-4 blocks my legs began to hurt.  I perserved and continued to wear them on different occasions but found no relief.  Bottom line is that I wound up with Achilles Tendinitis.  Needless to say they were a waste of money!
