I began purchasing Orthaheel shoes last fall.  My hips were aching so I was not able to walk too far or for very long.  I purchased one pair of Orthaheel shoes and wore them as my only shoe from morning till night for two weeks.  I couldn't believe the difference.  I could walk without pain and for long distances.  My hips didn't ache at night either.  So I am convinced that Orthaheel rocks!  Got rid of my other shoes and am committed to wearing Orthaheels the rest of my life.  I am 73 years young.
