My rain boots are too tight. How to stretch them?

You can stretch your rubber boots.
Sure, the best variant is to make a refund for shoes and buy a new one with the right shoe size. But if it is impossible, here is an advice for stretching your rain boots:

1. Put on boots with very thick socks.
2. Use a hairdryer on high heat and hold on places that you want to expand (toe and heel for a bigger size or the widest part of feet for making boots wider) for 15 minutes.
3. Walk around in the boots for 20 minutes to make them getting cold and save a new form.

This method is also great for making calf circumference wider.

If your rain boots are wider and bigger than you would like, for a better fit you can wear a thick sock or add an additional orthopedic insole. You can also choose special silicone shoe inserts for feeling comfortable in boots.
