[pct-l] Orthodics

[John.Hildebrand at trw.com (John Hildebrand)]

Hi.  Who has prescription orthodics?  I got a pair from my doctor...  They're carbon fiber inserts.  The specialist glued a cushoined insert (like a DR. Scholl's type) to it.  He then took out the factory inserts from my shoes and dropped these in...  

My question is :  Has anyone used these type and how do you change the cushioned part (it is glued to the carbon fiber part)?  

Can I just tear it off and glue some of those Superfeet (are they just cushions or actual arch supports) to them?  If so, what type of glue and how often did you change them?  

Thanks and have a great day!!
