Its not necessarily a science, but a form. If you have a vertical posture, land midfoot directly under your body and bring your legs toward your hamstrings, you use less energy. If you land with your heel and use the ball of your foot, not only is it hard on your ankle, but you use more energy by allowing yourself to lean forward and having to use your legs to drive yourself forward rather than maintaining horizontal momentum. Also if you swing your legs out rather than "pulling" them upward, that increases the energy needed to maintain your pace.
The arch in your foot applies to how your ankle and heel fall when running. If you have flat feet, or little to no arch, your feet will pronate inward and can cause discomfort or injury to the feet and ankles and impair your running stride.
If you have high arches, your feet and ankles pronate outward and can cause injury and affect your stride.
I asked that, because depending on the OP's arch in her foot, she may not have the correct support for her feet. Also try some hips strengthening exercises and stretches. A lot of problems that runners encounter stem from hips that aren't as strong as the legs.
Edit: It looks like you might have a slightly high arch but you can either Google pictures of a high arched foot, or find a reputable sports goods store/athletic shoe store and a salesman should be able to assess your foot and help you find a shoe that is both correctly fitted and comfortable.
As for the leg pain, are you stretching and allowing your legs to warm up? I would do a really good 5 minute stretch for each leg and a warm up of increasing speed for another ten.
Remember, warm up, peak performance, cool down. The warm up and cool down are very important parts of a workout. Without either, sustaining an injury is at a far great percentage than with w/u, c/d.
