if it cracks vertical thru the edge, so from snow to cap, and is cracked the whole way thru send them back, if it is cracked that way partially file it down so the craxk is gone. if it cracks again send it back. if it cracks horizontally send them back! cause that is dangerous to ski on cause it could split and rip into ur leg.
Ice, snow, man-made, slush, powder, as long as u land on your feet nothing else matters
