There are actually several types of skateboards but the most common ones are the longboard, cruiser, and carve skateboards. A longboard is usually at least 33 inches. It is a great mode of transportation and works well for cruising around. The cruiser also works well as a mode of transportation but many consider it more beneficial as it has a shorter skateboard, which promotes ease in transporting around.
Skateboarding started in California in the 1950s. The first skateboards were made from roller skates (attached to a board). Skateboarding gained in popularity because of surfing; in fact, skateboarding was initially referred to as "sidewalk surfing". Initially, skateboards were handmade from wooden boxes and planks by individuals. As the sport became more popular, companies started manufacturing skateboards. Boards are also continuing to evolve as companies try to make them lighter and stronger or improve their performance.
To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.
