Is there such thing? I have these wierd ares on both of my feet and my doctor said it is an allergic reaction to something, so I was thinking of shoes.

It may be socks even! See what you wash your socks in. Try diffrent brands.  Also, it may be the fabric INSIDE the shoe. Good luck!

If I wear shoes made of a certain material, my feet get sweaty and itchy.  But it could also be your socks or the detergent your socks are being washed with.  I lent a friend of mine a shirt and she washed it w/ her detergent and when I wore it, I got sneezy and itchy and my eyes watered.

Maybe the inside of your shoes are dirty? Or maybe it's the detergent you wash your socks with.
