Skateboarding is a very individual activity. There is no right or wrong way to skate. Skateboarding still hasn't stopped evolving, and skaters are coming up with new tricks all the time. Skateboarding has gone through its ups and downs over the years. However, since 2000, due to attention in the media and products like skateboarding video games, children's skateboards and commercialization, skateboarding has been pulled into the mainstream. As more interest and money has been invested into skateboarding, more skate parks, better skateboards have become available. In addition, the continuing interest has motivated skateboarding companies have to keep innovating and inventing new things. In 2020 Skateboarding will appear for the first-time in the Olympics in Tokyo, Japan.
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.
Each skateboard wheel is mounted on its axle via two bearings. With few exceptions, the bearings are the industrial standard "608" size, with a bore of 8 mm (or 10mm depending on the axle), an outer diameter of 22 mm, and a width of 7 mm. These are usually made of steel, though silicon nitride, a high-tech ceramic, is sometimes used. Many skateboard bearings are graded according to the ABEC scale. The scale starts with ABEC1 as the lowest, followed by 3, 5, 7, and 9. It is a common misconception that the higher ABECs are better for skateboarding, as the ABEC rating only measures tolerances, which do not necessarily apply to skateboards. Bearing performance is determined by how well maintained the bearings are. Maintenance on bearings includes periodically cleaning and lubricating them . Bearings that are kept unmaintained have their performance greatly lowered and will soon need to be replaced. Bearing cleaning kits are commonly available on the market. The ABEC rating does not determine the speed or durability of a skateboard bearing. In particular, the ABEC rating says nothing about how well a bearing handles axial (side-to-side) loads, which are severe in most skateboard applications. Many companies do not show the ABEC rating, such as Bones Bearings, which makes bearings specifically for skateboarding, often marketed as "Skate Rated". Each bearing usually contains 7 steel or ceramic bearing balls, although other configurations are used as well.
