Methods To Stretch Waterproof Boots Are Provided


    1. Ice Stretching
      This first method to stretch Waterproof rainboots is pretty neat and only requires some water, plastic Ziploc bags, and a freezer; all common household items.

    Ice stretching is a good method for small or medium changes, but you shouldn’t rely on it for full shoe size changes. Here is how to do it:

    Fill 2 sealable bags with water until they are about 1/3rd full
    Leave a tiny gap in the seal to press out excess air, then fully seal the bags
    Place the water-filled bags in each boot and make sure the water is making contact with all the surfaces inside the boot
    If you want to focus on a particular area like the heel or toe box, position the water specifically against those areas.
    Next, put your rubber boots in the freezer and leave them there overnight
    Remove the boots and let the ice thaw for about 20 minutes
    Remove the bags and try the boots on. Repeat if you need to make more adjustments
    This nifty method takes advantage of the unique properties of water. Unlike most liquids, water expands when it is frozen, so when the water freezes and expands, it stretches your boots.

    A unit volume of water expands by about 9% when frozen so this method can be used to stretch your boots maybe a centimeter or two, usually enough to make them fit comfortably again.

    A few warnings though: Make sure the bags you use are freezer safe. Otherwise, they could rupture, and the water can damage your shoe.

    By the same token, make sure you do not completely fill the bags with water or else they can burst when frozen.

    1. Heat Expansion
      You can also stretch your boots using heat. Heating rubber causes it to expand and you can repeat this process the more you need to stretch. All you need for this method are some thick socks and a house hairdryer.

    With a pair of thick socks on, put on your boots
    Turn the hairdryer on high heat and hold about 5cm-10cm from the boots.
    Focus the heat on specific areas you want to stretch, like the toe box or heel
    Once the boots have been heated for about 30 minutes, walk around in them for another 30 minutes
    Repeat the procedure as required
    The method takes advantage of heat to expand the rubber and stretch it. The benefit of this method is that it is very quick and can be repeated basically as much as you need.

    Essentially, you are just remodeling the boot around your foot so it will not only stretch but mold to the unique shape of your foot. This method may not be permanent but its quick method to get some short-term stretching results.

    Make sure you do not heat the rubber too much. Cheaper rubber boots can actually lose their integrity and start to melt if heated too much. Also, make sure the socks you pick are thick enough so that you don’t accidentally burn yourself.

    1. Use Stretching Liquids
      You can also buy special liquids that let you stretch shoes. These liquids chemically react with the rubber making it more pliable for a short period of time.

    It is important to find a stretching liquid that is safe for rubber. Some liquids made for leather shoes, for example, can actually damage the rubber.

    Lay down newspapers to catch any drips or spills
    Mix the stretching liquid in a 50/50 solution of alcohol and water
    Drip a small amount to make sure it is safe for your boots
    If it’s safe, apply the liquid to the spots you want to stretch
    Wearing a thick pair of socks, put the boots on and wear them around for about an hour
    Add more socks if you want more stretching
    This method is good, but it does mean you have to buy special shoe stretching liquid. It can often be hard to tell if these stretching liquids are safe for use on rubber.

    1. Use A Boot Stretcher
      There are several boots stretching devices on the market that let you target specific regions of your boots for stretching.

    Usually, these machines are meant to stretch the toe and shaft area of the boot and will not make the boot wider. All boot stretching devices work differently, but the main process is the same:

    Insert the stretching device in the boot
    Slowly activate the device and lock it into the desired place
    Put the boots on and walk around for a while after stretching
    Boot stretchers are great and made specifically for this task, but that does mean you have to go out of your way to buy one.
