We found a really nice place to get AFO Socks, both seemless and seemed, at a reasonable price. My 5 Year Old is a Habitual Toe Walker and Shriners in Tampa, Florida is helping her. The Website is KeepingPace .com
Good Luck. The Shoes are very good also.

Speaking of Shoes, if you get AFO shoes at "answer2" affilliates, Shriners offers a form you can just fax/mail into the company, and get the shoes for 28$ instead of $60. We love the folks at Shriners btw.
