If you're interested they're about $26.00. The e-mail address is http://www.flatfoot.com
Also, about shoes. I found this place, Executive Shoes, which sells Mephisto, Ecco, Birkenstocks, etc. and especially wide shoes. Their # is 1-800-240-7463, you should request ALL the catalogues they have, and if you're a woman,you should also request the men's as well. People have been writing about Mephistos on this board for a while.
Their shoes have big arch supports in them and they seem to have nice looking shoes. Be forwarned though, Mephistos and all these other shoes are about $200 and up, but worth the money I suppose if they help us.
