So your footwear is a little bit too small yet not small enough to warrant buying a brand new pair. This is when a stretching is a great way to save you money and get those small shoes to fit your feet properly again. But a stretcher will not work on all shoes and you may need to apply a shoe stretcher liquid to the shoe to get it to expand out enough for you.
Stretchers work best on natural materials like leather and suede. These types tend to enlarge easier and actually hold their size once you use the device on them. But in order to do so you may need to provide a liquid substance first.
This liquid will absorb nicely into the leather and loosen it up enough for the material to stretch out without ripping or tearing. If you just try it right out of the box, you certainly do risk ripping that leather because they aren’t going to be broken in yet and will be very tight and non-stretchable.
To apply the liquid you will just need to spray it on and let it absorb before you use the main device on them. But each liquid will work only on the material it’s made to work for. So be sure that you buy the one that is made to work on the material of your own footwear. The wrong type could discolor and ruin them before you even get the chance to try and stretch them out.
