I have arthritis in my knees and walk (a LOT) for exercise.  I really need good walking shoes but they have to be pretty flat or my knees cause me problems.  I also have wide feet so finding a shoe that is comfortable and good for walking is a challenge for me.  When I ordered these I thought they were pretty expensive but the reviews were so good I decided to give them a chance.  I'm really glad I did because I wear them all the time now.  Previously I always wore slippers around the house, now I have shoes that are comfortable enough to wear instead.
