Use a hairdryer to stretch and break in stiff shoes. Turn a hairdryer on to the lowest setting and point the nozzle into the shoe. Warm the shoe up from the inside for a few minutes, then turn the hairdryer off. Put on two pairs of socks and slip the shoe on. As the shoe cools back down, it will conform to the shape of your foot. This method is best used for shoes made from natural materials; it is not recommended for plastics and other synthetic materials as it may damage them.
