Replying to Help me out

ive been having problems with my boots. my dad bought them a half size too big cuz he wants me to use them next year too. k well my foots done growing and the toe is really wide. my foot moves around like crazy in them which is comfortable but i dont think it helps me when i jib. but thats my question, is it worth spending all that money for a new boot ( maybe spk or rampage) cause it will help me out, or will it not make a whole big of a difference?
