Love all the GO shoes by Skechers!  I am not a runner but walk as part of my daily exercise.  The negative heel took some getting used to being a walker.  But they are so comfortable that it was worth the time.  The only negative is the right shoe is a bit uncomfortable along the right side where the laces are.  I have to make sure that I tie the lace in a certain way as so the lace won't curl up and cause pain.  When I remeber to do that the shoe fits fine.
