Western boots never go out of style, so if you are into the cowboy look, investing in a good pair is worth every penny. But even the most well-made boots can stretch out after a lot of wear. So if you have a pair that has become too big, you don't need to wear two pairs of socks to make them fit. You can shrink the boots down using vinegar. It's a time-tested remedy that works like a charm.
Use a soft cloth to apply a light coat of leather conditioner to your boots. Vinegar can be dehydrating, so this will help to prevent your boots from drying out. Conditioner will also keep the vinegar from staining the leather.
Pour one cup of water and one cup of white vinegar into a bowl. Mix well with a wooden spoon.
Place a pair of cotton socks into the bowl. Let them sit for a minute or two to soak up the liquid.
Place one soaked sock into each boot, pushed up into the toes. Let your boots sit for two hours.
Set a hairdryer on a medium setting and begin to dry the boots on the inside and outside. Continue until they are halfway dry, leaving them slightly damp.
Place the boots in a warm spot in your home to finish drying. If it is a nice day, put them in shaded area outside. Don't set them in the direct sunlight, which can cause them to discolor.
If the boots have not shrunk to your satisfaction, repeat the above process one more time.
