I’ve been skating for about 3-4 years, I can kickflip, pop shuv it, front shuv, 180 and almost heelflips. I can ollie and used to be very good at them and could get them clean, but when I started practicing kickflips, it made my slide all weird. I can still ollie ( though it’s not as clean) but now when I ollie I slide with my pinky toe and that region, instead of the side of my foot. How can I fix my slide? When I try practicing sliding with the side of my foot, it doesnt feel like I can turn my foot that far towards the board and when I do it slowly to see what im doing, i still slide with my toes.Thank you.
The official record for the highest flat-ground ollie is 45′ (114.3cm) by Aldrin Garcia during the “Maloof High Ollie Challenge,” held on the 15th of February, 2011. You can watch the movie here. However, a groundbreaking moment in the lore of the ollie will always belong to Danny Wainwright’s ex record of 44.5′ (113.03cm, ELEMENT-HIGHEST OLLIE CONTEST Feb.6th,2000.) Reese Forbes, a competitor of Danny’s in this contest, was also well-known as a master of the ollie.

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.

Hey dude i want to push faster and constantly at the moment i am starting and stopping to much i would like to keep going is it because I’m not fit enough yet or am i not pushing correctly I’m regular stance…..should i put push down on my left knee while pushing for a while to keep my board straight?!!!! I also am trying to get my ollies down….. 🙂
Hey, I’m a girl too and I’ve been skateboarding for nearly ten years now. I’m not a pro or anything, but I used to ride around in the local skatepark that was mainly just a big bowl that was fun to just drop into and cruise around in. I’m only just now learning street tricks. Anyways, I’d go there and the dudes would sometimes tease me, but sometimes they’d tease me about it. The thing you gotta do is not give up. Just ignore them. Dudes are stupid. Practice at home, by yourself, and learn some awesome stuff. So when you get really good, you can go to the park and if they start saying bad stuff, show off. It’ll blow them away. It always made me feel really good to show them that I was better than them right after they teased me for it.
No one had ever seen anything quite like it before, but no one knew just how transformative that moment would become. It wasn’t just that you could simply pop up into the air, it’s that it gave the rider a whole other set of opportunities to do tricks, and you don’t even have to be dependent on a ramp! As time went by, people began to add other skateboard tricks while they were airborne.
Made with bamboo and fiberglass, this board is tough, flexible and ready for anything. The construction is designed to feel and act like a snowboard. The drop-through design is perfect for freestyle longboarding, commuting, carving, pumping and more. It gives you better stability and more wheel clearance. The board is definitely best designed for carving but tricks and kicks are easily done as well.

Popsicle - A Popsicle complete skateboard is typically between 30 and 34 inches in total length with a varying width between 6.0 inches wide and 9.25 inches wide. You can check out the deck size chart to pick the complete that will be best suitable for you. These decks all come with grip tape and are a more technical skateboard for tricks and for the skatepark. If you want to do more than cruise the streets, a Popsicle is what you are looking for. All of our complete skateboards include the deck, trucks, wheels, grip, bearings and hardware. They are all also fully assembled. When choosing a complete, typically the more expensive completes will include a higher quality deck, better and longer lasting trucks, upgraded wheels and a higher abec rating on the bearings.
Mounting hardware is a set of eight 10-32 UNF bolts, usually an Allen or Phillips head, and matching nylon locknuts. They are used to attach the trucks (and any type of risers) to the board. Some sets have one different colored bolt to show which side is the nose of the skateboard. Hardware is available in various lengths for mounting trucks with or without risers.

So now that you have an idea of what size and shape board you like, it’s time to choose a brand. A popular size is an 8.5 skateboard deck. If you were looking for a size 8.5 skateboard deck, you could narrow the decks offered on CCS.com to fit in the 8.25 - 8.5 range. This will show you all the boards in that range, and significantly reduce the boards you have to look through. Now, if you don’t have a preference on board brands, find a graphic you like and you’re all set. If this is your first skateboard or are still learning about what wood and brands you prefer, we recommend checking out a CCS Skateboard. They give you a bang for your buck, that's for sure.
The Rimable Complete 22″ Skateboard is the most compact street board that are ready-to-use.  It is best for exercise and fun, and very portable.  There are five colors that you can choose from Black, Blue, White, Purple, and Green.  It has high-quality construction, with a high-density plastic deck.  It features extremely smooth 59mm wheels along with ABEC7 bearings and solid aluminum trucks.  It measures 22″ long and 6″ wide and weighs 4 pounds.  It has the best rating of 4.3 on Amazon.
In this modern era, manufacturers are incorporating hi-tech processes and top-shelf materials into the construction of the skateboard. Companies such as Almost have several versions of hi-tech decks such as the Impact, Double Impact, and Uber Light Series. Element makes Highlight decks with inlayed fiberglass beams, and Foundation has its signature Fiberprime decks. Other manufactures such as Flip, Habitat, Plan B, Skate Mental, and Zero offer boards with high-end P2 Construction. Hi-tech decks differ from traditional 7-ply Maple in that they are inlayed with Carbon Fiber, Fiberglass, Poly Ply, or Kevlar to produce a stronger skateboard with more pop. For more options, head over to our stellar selection of Hi-Tech Decks! Although hi-tech decks have made a strong presence within the market, standard 7-ply Maple remain the gold standard. This is due to the solid feeling and pop afforded through layering 7 Maple wood veneers together. The large majority of skateboard decks offered are constructed of 7-ply Maple. Most board manufacturers offer both high-tech decks and standard 7-ply Maple. No matter what you desire, CCS offers a complete selection in multiple sizes, shapes, and construction types!

The board is shaped like a cup in the center, and has whale tails on both ends, designed to make tricks easier to do. The blue stain on the board looks like the picture. It has a semi flat finish with no lacquer top coat. The underside is plain which allows the owner to add stickers and graphics if they want but they look great just the way they are.

Before we show you how to ollie, let’s get familiar with the legends that brought this skateboard trick to the masses.  If it were a person, the history of ollie would start way back in 1974, when Alan Gelfand got his first skateboard from his father after his family moved to Hollywood, Florida from New York state. It didn’t take him too long to get the hang of it; he won the South Florida Skateboard championships two years later.
My son seems to have a lot of fun riding this skateboard. He will be out there doing tricks for hours. One evening when he took a break, I decided to see if I could still ride. When I took off down the driveway, I could feel how smoothly the wheels rolled. I used to have to pay extra for wheels like this when I was his age. Lost in thought, I coasted faster, and my neighbour didn't see me when I shot out of the driveway. Even though this thing flew several feet in the air, bounced, and came to rest more than 20 feet away, it had no visible damage! Not so for me. I loved the skateboard, but am now recovering from two broken ribs, torn neck cartilage, and a cracked pelvis. Still, this board rides like a dream!
I have been doing ollie’s for about a year to a year and a halve, but thats not the problem. My problem is the board turns when i ollie, i cant help it, i am starting to go into harder ground (ollying off ledges and ollying stairs) but i cant land and ride away because my board has turned in a 45 degree angle and it jerks me off the board, Please help in all you can, cheers mate.
Decks come in a variety of shapes and sizes. You can choose a mini-board, a cruiser, a drop-through or a standard deck for your favorite set of wheels and hardware. Widths range too from a few inches with a 22-inch board to the wide size of a true cruiser. Some decks are flat as possible while others are significantly concave for optimized turning. You can buy a deck with artwork and grip tape already attached for a quick install or you can get a bare-bones wooden deck to truly customize.
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.

The Powell Golden Dragon 2 Skateboard is an affordable and complete skateboard for the beginners and also for the advanced skaters.  It has high-rebound, hand-cast polyurethane wheels to give you a great roll and grip.  It measures 7.5 inches wide with a colorful screen-printed bottom.  It is made in China and has an average rating of 4.2 on Amazon.
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.
Hi, I can do an Ollie for 1 month already but somehow my Ollie is always unbalanced, meaning the front nose pops much higher than the back wheel. I understand that this is due to my front foot not sliding up higher, but I’m not sure how to correct it because my foot seem to get stuck after sliding up about an inch. Is it because of wrong technique or lack of calf muscles?

Skateboards are for people who want to try something new and extreme.  If you have not given it a shot and you want to challenge yourself then you should try skateboarding.  It is a fact that there are certain risks that go along with skateboarding.  However, skateboarding can teach you to balance and it is also a great way of losing weight.  Skateboarding can also help you in making friends while you are in the park.  With skateboarding, you can learn perseverance and build confidence.
Skateboards can be bought online and in your local stores.  However, choosing a good skateboard can be challenging.  If you are a beginner there are a lot of things that you have to consider.  Aside from the cost, you should also check the entire board such as the wheels, the deck, the trucks, and others.  Here, we have compiled the best skateboards for sale that you can choose from right now.
