Patty Patty is absolutely right with addressing your concerns. Some foals are born this way and quickly come out of it if approached correctly. I have just been given a 6 month old foal, was wild, now will pick up feet, so I can get him trimmed. He stands with his back feet well under him. However, attampting to shorten the toe from the bottom by paring out sole too much can sure sore them up.
Most farriers know what to do. .
