It has been a problem I have had on and off for quite a few years now. I have tried the shoe lace thing and it does work most of the time. However, the way I have got rid of the problem most of the time has been by using half insoles, to raise my heel just a bit. See, I was told years ago, that the pain may be coming from a short Achilles tendon. Now I do not know whether this is true, but it definetely worked for me. Careful, though, cos using the insole will also make your foot to be more tight in your shoe. Try it. It worked for me. And the half insoles are not expensive.
