I ordered these for my first track day. Was pretty excited to get them, but tried them on, but they for a bit small. I ordered them in a 44 (11 US) and my toes are a bit cramped. I also had a hard time getting them to zip up over my leathers. I'm going to order another set, though. It's a great price for good boots. I'll just pass the smaller set on to someone who can fit them.
