Step 1: Decide what kind of Skater you are.
CRUISING: This type of Skating is an older style of the sport, and is more about having fun going fast than doing tricks. These Skaters use fish -decks (the ones with a fat, pointy nose) and extremely large wheels for superior grip and turning. These guys don't do a lot of tricks, so the coolest one is probably a 360 shove-it, they mostly just ride around fast.
STREET:Easily the most common and by far my favorite Skater, because I am one. They do crazy flips and grinds, like the Tre flip, or the backside tailslide, and often hurt themeselves , the reason cops will tell you to get going from a good skate spot , so you don't sue the establishment if you get hurt.
PARK: A combo of Vert and Street style Skater, Who skate at parks , transfer bowls and gap stolen street barrels. They will usually add found/stolen items to the park to incorperate them into the layout of the park and ollie over them, or sometimes even grind on them.
Step 2: Vert setup
Wheels: 55-65 mm. 95-99d
Bearings: Bones Swiss or a really high ABEC
Step 3: Cruising setup
Wheels:70-85mm,66-77d(Jelly-Wheels, so if you hit a pebble at 35mph you don't fall off).
Step 4: Street/Park setup
Deck: Whatever feels comfortable to your foot size(I use 7.5,but its weird cause I have size 12 feet).
Bearings: Bones Swiss again
