As a long time runner, running, track and cross country coach I will stand by my advice, correct your running form to ensure you are not landing with a heel strike. Treating problems with shoes, stretches and whatever else does not correct the problem since it does not deal with the cause it only deals with the symptoms.
It is called WORK-ing out for a reason.
I said getting fit was simple, I did not say it was easy.
Cardio burns calories, strength work burns fat.
Eat well to lose weight, exercise to get fit
You can not build a six pack using twelve packs
Often when we seek a magic bullet for fitness we end up shooting ourselves in the foot.
