I wear these inserts for a few days. I have no heel spur, but rather a problem that is caused by a change in posture. The good arch support will allow me to make again more walks. The effect also stops when I run after without deposits, is when the foot to be supported by the relaxed (or has not even tense). If the pain come back, relieves running with insoles very quickly. I further ordered me insoles to equip several shoes with it. The foot is optimally supported me the sole does not slip and also the tightening is no problem. If necessary, I would imagine that with such a problem, a piece of double-sided tape could remedy.
