Pressure and friction from tight shoes can cause blisters, which form when the upper layer of the skin separates from the lower layers. For the protection and relief of these painful areas, Compeed is the ideal choice. It is specially designed to cover blisters as soon as you feel the characteristic pain, so you can continue your activities without discomfort. It is recommended to replace the patch frequently, and it is also good to let the wound air out for better recovery.
