The size is 49, which is oversized because it's designed to be used with a liner. My normal shoe size is typically a 13/14 or 47/48 depending on the brand. My feet are 30cm long. The 49 fit me well with a wool liner and thick socks.
Asking $300, these go for about $1,300 on the Alfa website. I mostly just want them to go to someone that can use them and get a little back that I can offset my new bindings.
Feel free to ask questions, make offers, whatever.
