OK best position is between the balls of your feet and your toes, if I am on the balls of my feet I still drag my toes. Move your feet back and stand up, when you move them back to far it will feel uncomfortable or hard to stand, that is to far. You want to be able to support your weight fully with your feet back as far as you can, adjustable rear sets would allow you to be on the balls with more ground clearance. Toes should point outward about 20 degrees, heels should rest against the heel guards. All your shifting and braking should be done before you start your curve, a good 40-60 feet before at this level. Get your feet into position, sit in the garage and practice moving your feet back and forth till it feels right. You want your toes pointing out so it opens your hips, if you are sliding off the bike you don't want to rotate your hips. If you rotate your hips your toes will try to point forward, instead slide your hips parallel to the bars to the side, and drop your head to where your mirror is. You will see why your toes should point out at that point. Do all this sitting on the rear stand or even the kick stand, but you will see what feels right.
It will feel very odd moving your feet so much at first, but its what you need to do to be right. Remember you wont be shifting in the curve and you should not be using your rear brake at our level either, so in the straights feet forward, brake, down shift, move feet back, start the turn, apex, throttle out, move feet forward. Practice it in the garage for about 10 min a day for a week, it will feel natural after awhile.
