Replying to Boots

ok so i was teaching a lesson in my rossignol free-x (orange) boots and got slammed by a boarder not watching where he was going. everything was cool until the end of the day i noticed that one of the rivets that holds my bottom buckle into the boot was out so my buckle was screwed up. there was also a crack which got bigger when i put them on and skied them today. i didnt talk to any shops yet but im assuming they cant fix it. i was thinking of epoxying the crack, then finding a way to stick my rivet back into the boot. im also guessing i'll need new boots and im not sure what to get. I ski mostly bumps and park but i also teach a lot of lessons and then i race a good amount. are there any freestyle boots that are comfy but i can race in? also if you know anything about boot repair can you help me out?
