I don't know how many of you wear AFOs but this may be helpful if you do.
There is a website for socks designed to fit under AFOs:
http://www.sock-em.on.ca/
You can place orders from there.
We have used these socks for the past year and have been VERY happy with
them. We originally ordered 4 pair. Anthony wears them every day, all day and
they are still in good shape. They have gone up in price since we ordered
but I think they're still a bargain! (remember $9 CDN = approx. $6 US or less)
