Sometimes new shoes come with a price larger than the one on the tag -- a raw heel. The stiff leather on the back of a new shoe has a tendency to rub against the back of the heel and create either a blister or a cut. The good news is there are several ways to keep this from occurring without breaking the budget.
Wear thick socks to prevent too much rubbing on the back of the heels. This will work well in the colder months but may not be viable in the summer.
Place a cushioned adhesive bandage on the area that is rubbing on the shoe. This will prevent the stiff area of the back of the shoe from rubbing directly on the skin.
Purchase heel inserts that slip behind the heel to prevent any direct contact between the back of the shoe and the back of the heel.
Cut a potato halfway open and slip it over the back of the new shoe for 24 to 48 hours. The potato will help to condition the leather in the shoe and remove the stiffness.
