I went with my girlfriend to the Good Feet Store for my one year refitting. When I was finished, I encouraged my girlfriend to look try out the inserts, since she had back aches. She was skeptical because she didn't think inserts would improve her back pain. After the consult, she went ahead and purchased the inserts from Rich. Three days later she noticed her back pain was gone! Now, a few months later, she's not had any daily back pain....as long as she wears the inserts. She uses the insoles while at work, and also on the tread mill while exercising. Thank you Good Feet for giving my girlfriend a better quality of life!
