Replying to Proper Boot Fittings

Alright so last time I bought boots they told me my big toe should just barely hit the end of my boot so when you get into the knees bent skiing position your toe wont hit any more and you will have a little room. So is this correct? Im going to get new boots soon and I may have to get a half size bigger... witch means remounting bindings but anyways how should they fit my feet, like the people told me? I really need them to fit perfect because i cant stand shin bang anymore
