Slam your back foot down on the tail of your skateboard as hard as you can. At that moment, you want to also jump into the air, off of your back foot. This part is key and takes practice. The trick is in getting your timing right. You want to slap the skateboard’s tail down, and as it hits the ground, jump off of that foot into the air. Make sure to pull that back foot high into the air. It's a quick, snapping motion.
The wheels of a skateboard are usually made of polyurethane, and come in many different sizes and shapes to suit different types of skating. Larger diameters (55–85 mm) roll faster, and move more easily over cracks in pavement and are better for transition skateboarding. Smaller diameters (48–54 mm) keep the board closer to the ground, require less force to accelerate and produce a lower center of gravity which allows for a better response time, but also make for a slower top speed and are better for street skateboarding. Wheels also are available in a variety of hardnesses usually measured on the Shore durometer "A" scale. Again like car tires, wheels range from the very soft (about Shore A 75) to the very hard (about Shore A 101). As the A scale stops at 100, any wheels labeled 101A or higher are harder, but do not use the appropriate durometer scale. Some wheel manufacturers now use the "B" or "D" scales, which have a larger and more accurate range of hardness. Modern street skaters prefer medium-sized wheels (usually 51–54 mm), as small wheels with lighter trucks can make tricks like kickflips and other flip tricks easier by keeping the center of gravity of the skateboard closer to the deck, thus making the deck easier to spin. Street wheels are harder (A 100/A 101). Vertical ramp or "vert" skating requires larger wheels (usually 55–65 mm), as it involves higher speeds. Vert wheels are also usually slightly softer (A 98/ A 99), allowing them to maintain high speed on ramps without sliding. Slalom skating requires even larger wheels (60–75 mm) to sustain the highest speeds possible. They also need to be soft and have better grip to make the tight and frequent turns in slalom racing. Even larger wheels are used in longboarding and downhill skateboarding. Sizes range from 65 mm to 100 mm. These extreme sizes of wheels almost always have cores of hard plastic that can be made thinner and lighter than a solid polyurethane wheel. They are often used by skateboard videographers as well, as the large soft wheels allow for smooth and easy movement over any terrain.
In the case that you didn't gave up after a hundred over tries, you'll start to develop a reaction to landing it. After a few hundred more tries, you'll feel you are getting off the ground and getting little air. And once you reach the thousandth try, you'll already be doing it whilst rolling and the next thousandth tries will be spent on clearing small cracks n obstacles and working towards ollieng up bigger obstacles n up ledges.
Longboard - A longboard is similar to a cruiser in terms of overall use and getting around town. Longboards start at about 42 inches in length and about 9 inches in width. When you buy a longboard, the wheel base of the trucks is usually wider and they have wheels starting at roughly 60mm. This gives you more maneuverability and a very smooth ride.
Learn how to ollie off of a ramp: Ramps are a LOT of fun to ollie off of, but they are also a great way to break something if you don't know what you're doing! I have a cousin who almost lost his arm because of how nastily he broke it while ollying off a ramp. But don't let that scare you - if you know what you're doing, ollying off ramps is great!
Bought as a Christmas gift for our nephew. He's not an expert or anything so I was looking for something that would work while he gets used to riding one. When I received it I pulled it out of the package to check it out and the construction was good. The wheels spun smoothly and the grip tape was nicely put on. I don't know how it would resist to some board slides but for a 15 year old just starting out its a good board.
Almost is proud to announce a collaboration with Skateistan, the award-winning non-profit organization empowering children and youth through skateboarding and education. They recently launched a new Skate School in Phnom Penh, Cambodia on Friday (February 23rd, 2018). Over 100 children celebrated alongside special guests from around the world, including Almost flow skater Sky Brown. 
It is mainly because those items are guaranteed to help you familiarize yourself with the ins and outs of using them. They are a big help in making you feel comfortable when you push off with your feet while also balancing on top of the board when riding. It is not good to go for a very technical product, so it’s best to choose the mentioned types first.
