I did not like these shoes - only wore them once to run and the next day both of my knees were hurting.  Tried to give them to my sister and she said they made her feet feel like they were in an awkward position.  I bought these on a recommendation from a friend.  I'm going back to my New Balance shoes.  Unfortunately I didn't try these out right away when I got them and now I'm stuck with them.  They are very pretty but my knees are still hurting from wearing them.  They are also very small - I wear a size 8 but these were smaller than my New Balance size 8 shoes.
