fetus, i'm not going to rag on you because you are obviously just uneducated.
if a boot fits properly, it will not hurt you. obviously if you are in a race plug, it might start to wear at your shins. most good park skiers tend to use high performance fitting boots anyways. look at anyone not on salomon. they most likely use the one off race boots becasue they are strong skiers. you still need to control your skis in the park.
as for freeride features. you can find tons of high performance boots with padded tongues and soft boot board. any boto that does not have a leather race liner has a padded tongue. if it is too padded, you can't get a good wrap on your shin and you will casuse problems anyways.
you can make soft boot boards, or replace hard boot boards no problem. these do make a difference. however, the majority of boots (esp. freeride ones) come with a rubber boots board.
as for flex of a boot. dont even worry about that when you buy a boot. you can almost make any boot on the market have any flex you want. just make sure that the flex is right for you. "soft" is not the right answer for park, "correct" is.
