A complete skateboard is pre-assembled - it almost rides right out of the package and on to the streets, ready for you to practice all your new tricks. You simply don’t have to think about buying the separate parts like trucks, wheels, decks or the likes. Once you have gained more experience on the board and you feel like customizing it to fit your skateboarding style, you can begin to learn more about the different pieces in order to assemble a skateboard that meets your specific wishes and demands. Until then, a complete can be quite the right choice.
Place your back foot on the edge of the tail (this is where you will apply a burst of force to the skateboard) and prepare to exert force through the foot’s ‘big-toe-mound’ area. Place your front foot behind the front bolts. Make sure the weight bearing down on your feet, as well as the weight of your body, is generally centered over the ‘middle line’ of your skateboard.
So the proper foot placement for the ollie is with the ball of your back foot horizontal on the tail of your skateboard. And your front foot centered on your board right behind the front trucks. You may find that moving your feet around in different positions are more comfortable. This is fine, everybody can learn how to skateboard their own way.
