Replying to Buying boots without a boot fitter

basically i need new boots. I want something that will be comfortable and forgiving in the park. I would usually go to a decent shop to buy boots but where i live there are none that i can find that have a great level of expertise. based on what i want out of the boot, does the fit really matter that much, as i will not be doing any technical skiing in them. and should i just go for a less aggressive fit? help please
