For the past five years I have been wearing K Swiss tubes.  With my job I am on my feet a lot either moving around from place to place or standing.  At the end of the day my feet don't hurt with the cushion and memory foam inserts, I love my "tubes".  The last year or so it has been becoming more and more difficult to find  the tubes.  Guess they have redesigned and are not making them lIke the were.  I bought these and from day one they hurt my feet.  They run small and have no support.  I would have returned them after trying them on but since I had always been so happy with my tube purchases I threw the box away.  I since I could not send them back I tried wearing them 2 more times with no success. Very disappointed with these shoes
