I went in here after a number of days where my the outside of the bottom of my right foot was killing me. I could hardly walk without grimacing. They first had me step onto a sensor plate that measured my surface contact points. I was very flatfooted. They went over to a number of shoe inserts, measured them against my shoe and chose one that was the right size and level for me. I have been wearing them ever since and have not had any problems with my feet. I also bought a pair of Kenkoh sandals that I wear every few days and, although at first they made my feet ache somewhat, now they feel fine. They come with claims of healing the feet. All I know is that I can now walk and am not limping around the house as much.
