Dr Cherri Choate wrote in her blog entry last week about research demonstrating that a cushioned topcover can act to reduce shock.  You can read her entry here and you can read our eJournal Club article on the subject here.   

Based on this article, my standard cover for runners is now a 3mm soft EVA cover to the toes with 1.5mm Poron gluded to the bottom of the cover.   This combination not only provided excellent cushion but has been shown to hold up well. 

I also recommend to my serious runners that they have two pair of running orthoses.  That way they can rotate the two pair when one needs to be refurbished.   Like running shoes, I recommend replacing the topcovers every 400 miles.
