Boots are the most important piece of your setup. If your boots are too small they'll cut off circulation to your feet making them cold, they'll hurt like hell because of pressure points, and it's not uncommon for toe nails to turn black &/or fall off after a long painful day of being pushed up against the end of your boot. On the flipside. If your boots are too big, you can get painful blisters, and your board will be harder to control because your feet will be lifting and sliding around in your boot, causing a lack of responsiveness. Either way you're in for a shitty experience. Go to your local board shop and try on TONS of different brands and styles. Boots will also "Pack out", which means as you break them in, the materials will loosen and stretch, and they'll become half to sometimes a full size bigger. So ask the guy or girl at the store to give you a hand.
Now a lot of boots have the lace up style tightening systems on them. However after experiencing Burton's "speed zone" lacing system, I hate regular laces and will never go back. Laces are a huge pain in the ass and they take a lot longer to make minor adjustments. Look into speed lacing systems or Boas, pretty much all brands have these as an option and you won't be sorry.
As stated above already, you can get different levels of stiffness when it comes to boots. A soft flex boot will be more park friendly when compared to a stiff flex which is made for straight-up bombing. I agree with you benefiting most from a mid-flex, just keep in mind the feel might be fairly stiff until they pack out a bit.
Either way, don't try to save money on a shitty pair. You can either be in complete pain for 3 hours before you quit and sit in the lodge for the rest of the day, or you can get the right pair that feel like butter and spend 8 hours killing it. As well, a good pair of boots will last you years and years if you take care of them, so do it right the first time.
