The easiest way to take advantage of special tools that offer an abundance of the most famous manufacturers - Salton, Twist, Salamander, Kiwi and many others. Stretch marks are in the form of foams or sprays. Just put them on the outside and inside the shoes and then put on thick socks on them - zhmuschie boots and walk until the vehicle is dry. Such manipulation is usually necessary to make a few days: as long as the shoes do not stretch.
If you for some reason you can not buy a brand stretcher can be made similar to the liquid alone. Mix 3 parts water to 1 part isopropyl alcohol and wet with this fluid boots inside and out. Now they have to break in, until they are just right.
If you do not want to suffer in tight shoes, you can go the other way. Just type boots at night with wet newspapers and leave until morning. They are slightly stretched. If this is not enough, repeat the procedure. If instead of newspapers will use white paper - not undergo favorite shoes at risk of excess dye from the inside.

Water freezes and expands on the laws of physics. Boots stretch. But this method in any case can not be used for boots made of artificial leather - it will crack from the cold.
There are also special wooden stretching device for shoes. You can try to buy it. But by using heat to act on the skin is not necessary, although some "experts" advise to resort to using a hair dryer or iron - there is a risk to damage the boots.
