In one sentence, describe what the following article is about: For this type of DIY upgrade, you can’t go wrong with a ball of natural beeswax. Beeswax can be found in most hardware stores, where it’s commonly sold as a lubricant. If you’re unable to get your hands on beeswax, a clear, odorless paraffin wax candle (such as a tea light) will also do the trick.  Whatever type of wax you go with, just make sure it’s not dyed, or you risk staining the shoe. If the shoes you’re trying to waterproof are expensive or irreplaceable, you might want to use one of these products just to be on the safe side. To ensure that the wax settles properly, you’ll want to start with a spotless surface. A quick wipedown will help remove dust and light debris. For older pairs that have seen a lot of action, it may be necessary to send them through the washer and dryer before you start waxing.  Waxing the shoes without cleaning them first will trap dirt happens to be clinging to them. And, since they’ll then be waterproof, cleaning them after the fact can be tricky. Make sure the shoes are completely dry before you proceed. If you’re anticipating bad weather, it may be a good idea to wash old shoes a few days before you plan on wearing them. Before you start rubbing away, make a small mark low down on the heel or sidewall of the shoe close to the outsole and see how it looks. That way, you can make sure it won’t stain. Keep in mind that much of the contrast will be eliminated after the wax melts.  A colorless or off-white type of wax will be the least conspicuous and blend smoothly with the materials and colors. If you're using a colored wax, make sure it matches the hue of the shoe as closely as possible. Rub the wax back and forth vigorously to form a thick layer over any part of the shoe you want to make off-limits to moisture. Really dig in. Imagine that you’re coloring with a crayon. Pay particular attention to the areas around the toe, heel, sidewalls, and laces where water has a tendency to seep in.  Double check that you’ve coated the whole shoe. Any spots you’ve missed will be vulnerable to leaks. As the wax builds up, it will cause visible discoloration. Don’t worry—this will disappear as soon as you apply heat. Switch on the hairdryer to let it warm up before blasting the shoes.The more intense the temperature, the faster and more completely the wax will melt. Hold the nozzle close to the surface of the shoe so that the heat is better concentrated. Go over the shoe slowly, turning it or angling the hairdryer as needed. You should notice the wax beginning to fade into the shoe almost instantly. When you’ve got one shoe done, move on to the other.  It may take half a minute or so for the heating coils in the hairdryer to warm up enough to melt the wax. Do one shoe at a time. That way, you’ll have a helpful visual reference to tell you when the wax has completely set in. As it liquefies, the wax will become integrated into the fabric, sealing the tiny openings and creating a barrier against moisture. It will then re-harden as a clear, protective layer. The finished shoe should look no different than it did before you waxed it.  Look closely for any unmelted sections that you might have overlooked before you put the hairdryer up. Wax is naturally water repellent and non-penetrating, even on the most porous materials, so it won’t harm the shoes to become part of their construction. All that’s left to do now is see how well your experiment worked. Pour a cup of water over the toe section of the shoe. The water should bead up and roll right off. Congrats! You can now go forth fearlessly no matter how soggy it gets outside.  If the water is being absorbed, you may need to apply a second and more thorough layer of wax. Be sure to wait until the shoes have dried before adding more wax. You won’t be able to go swimming in your new-and-improved shoes, but getting caught in a light rain or traipsing through a snowy meadow should no longer be a problem.
Summary: Grab a hunk of beeswax or colorless candle. Clean the shoes with a damp cloth, or wash dirtier shoes. Test the wax on an inconspicuous part of the shoe. Rub the wax all over the outside of the shoe. Set the hairdryer to high heat. Wave the hairdryer over the shoe from front to back. Continue heating until the wax disappears. Test out the waterproofing.
