they will blow up, we just had a pair returned for the second time cause of that, the first pair blew up one ski, salomon sent one slightly used ski to replace it, basically new, the kid skied a few times and it blew up once again, cracked the edge out, then the ski separated/delamed from the toe to the heel piece, hammer it back in, and fill it with apoxy, thats the best youll do for it
