A way to get higher toe touches is to use the wall as resistance. To get started, find a wall (wide enough for your legs to spread out on) and then lay down on your back (facing the wall). Next place your legs against the wall, pushing your butt up against the wall as far as it'll go. At this point, your body is in an "L" shape. After that, slowly open your legs until you start to feel a stretch. Stretch them as far as you can. As the days go by, gradually your legs should go lower and lower and it'll start to look like you're doing the splits on the wall. Do this each day for about 5 minutes.

Summary:
Stretch your legs against the wall.
