Product Review

As your heel rubs against the shoe -- or a strap rubs against your foot -- the skin becomes irritated and inflamed.

If your feet are sliding forward in your shoes, causing the shoe to rub against your heel as you walk, try some insoles or heel cushions. These keep your feet firmly in your shoes, eliminating rubbing and friction.

Another thing to remember -- nobody's feet are the exact same size. One may be slightly bigger or wider than the other, leading to one normal foot and one blistered foot. Grippy insoles and heel cushions can help alleviate this problem for the ill-fitting foot.
