I ordered this shoe to try to give me the ability to lesson the impact of walking on cement floors.  My rolfing therapist told me not to use these types of shoes, as they give an unnatural motion to feet, knees, hips and back.  Who knew?  The shoes looked well made and durable, but I sent them back.  Please check with your therapist if you are having any issues with "joints" before you buy these shoes.
