ill give ya a real answer man, I ride in the Dalbello Il Moros which I love because of the liner being heat moldable which makes it a super comfy boot and the large strap up to gives an little and helps with shin bang because it spreads the area of impact out over a larger area.
I also think the SPK is a sweet boot it just feels really open inside to me and I like a boot that I feel locked into, I know a lot of kids who ride park like the comfier looser feel though.
Really a bootfitter will be best for ya because they will look at the width of your foot and that makes a big difference in which boot will be best for you. Also whether you ride park or not getting a custom insole will cost you a bit more but you will be thankful because they help so much comfort wise.
Good luck man
