ok, there are some guys that kill it with soft boots. IMO, stiffer boots are just as good in park(maby a little less forgiving, but if you have decent form you'll be fine) and are for sure better at big mountain/anything except park, even though you can still use them. By real skiing I meant stuff not made with shovels and groomers. There are also skiers that killed it in rear entry boots.
forgot about bootboards, that's important. Make sure to get a FT with a rubber bootboard. All the shells are literally the exact same fit with different colors.
