I've been wearing semi-ridgid custom orthotics daily for about 1 month, with cotton socks.

After about 2 weeks, I've got a rash on the bottom of both feet within the arch area.
I never had this problem before. It first started on the left foot and then the right foot.

There doesn't seem to be any air cirulation on these orthotics.

Are people allergic to these??

Anyone else ever have this problem??
