Its a back foot! I will be posting more references soon, including bottom photos and showing Neosho crossing his back legs cause its just funny.

P.S. Yes I know his feet look really rough right now. As a general rule his feet are way too small for his body mass and normally suffer from chronic cracking and a bout of abscesses about five months ago just made it worse. He is comfortable, sound and cared for, just looks rough. ^_~
