My podiatrist said the machine can diagnose but the inserts are crap. having said that the machine diagnose is not a substitute for a dr. He recommended the Powerstep inserts that are sold in athletic shoe stores. Some of them have trained salespeople that can watch you walk and help you find shoes or inserts to help you. I have a high arch and always bought shoes with an arch in them- some fit right and others not. When I put them in my shoes, it felt like a golf ball under my foot. Theynalso run about $40 and last about 6 months. I also got custom orthotics from my podiatrist.. No more high heels or flat sandals for me. There is a brand of shoe for high arch people and some of their shoes have removable insoles to wear with orthotics. I haven't purchased any yet as they are very expensive-$100-185 perpair. The brand is NOAT. i am hoping to sell a lot of my shoes to help pay for a pair of these. I hope this helps.
