Why are you running POSE? Were you having problems before?
POSE stresses your calves and ankles rather than your knees and shins. There is generally nothing magic about it and I find it very overhyped but it may be right for you. it is up to you to experiment.
It is impossible to diagnose your running style over the net and the POSE guys generally want too put you through seminars and get you to buy their DVD in order to learn to run their way.
The best advice is to be light on your feet. I find a mid foot strike suits me best to keep impact to a minimum. Do what feels right to you.
