Billy Footwear Billy Cozy 2. Size 12M. The black ones show the most wear. Although my kiddo can not walk, she wears them over her AFO’s while riding around outside in her wheelchair in the winter. This past winter we thought we lost one and so I bought the Chestnut ones. And then we found the other black one! So the Chestnut ones are unworn. Since they are the same size you can have the black pair with the purchase of the Chestnut pair. We’ve grown out of them now.
