According to my service entrance exam I was in sound condition when I entered service. Each item was checked normal including my feet. Four years later while going thru my Medical Evaluation Board the Doctor checked that my feet were abnormal and told me I had Pes Planus. After I got out of the military I went to the Podiatry Clinic at the VA and they told me I had severe flat feet. For the next several years they have provided me everything from shoes to inserts. I have 20 years worth of VA and Civilian notes stating that I have severe flat feet. I filed a new claim for flat feet. My question is do I have a good chance for service connection and "presumption of soundness."
