i hope u realize that u dont need park boots to ski park!
but u should defenitly see a boot fitter and get boots that fit, thats a hell lot more important then whats cool and what ns says. a good park boot or any boot wont help u, but instead hurt u, if its not right for ur feet! go to a boot fitter!
other then that good park boots are fulltilts, saloman spk, and many other brands but dont get a boot cause it looks cool, get one that fits and works for YOU!
hope this helps! good luck
