It does take the knee load off when you first put them on.  But then after awhile your legs/knees hurt from having no support on the bottom.  They are very comfortable and soft.  It is comparable to walking barefoot but with a rubber bottom on the shoe.  Makes you more mobile.  I have a high arch and need that support in order to walk normally.  Flat shoes are very uncomfortable.  This is a good shoe for around the house only.
