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.
To summarize, a skateboarder's feet need to do two things successfully to complete an ollie. They need to provide a changing force to move the board correctly (so that the combined force of gravity and the skater's feet add up to the green arrows above), and they need to provide different amounts of force with each foot (shown by the red and blue arrows above) to steer and turn the board into the right orientation.
As you jump into the air, your front foot needs to roll slightly inward, and with the outside of your foot, you want to guide the skateboard as it flies into the air. Some people describe this as dragging the side of your front foot up the skateboard – that’s more or less what is happening, but what you are doing is using your shoe and the grip tape on the board to pull the skateboard higher into the air with you, and guiding the skateboard to where you want it.
Finally, just roll away. If this sounds simple, then great – get out there and practice! If this sounds too complicated, don’t worry. Just go slow, and take your time. There is no time limit to learn how to ollie – some people learn in a day, and I know one guy that took over a year to learn how to ollie on his skateboard. Also, like with most things in skateboarding, your body is learning how to ollie more than your mind is. So, with practice, you’ll eventually get it.
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.
