Top tips for stretching canvas shoes
The first and perhaps the most convenient method for loosening a pair of canvas shoes is to dig out a pair of thick socks. You can wear these with your canvas shoes to slowly stretch the material without hurting your feet.
Find a pair of winter socks and wear them inside your new canvas shoes
Tie your shoelaces as you normally would, making sure they’re not too tight
Wear your shoes around the house for a couple of hours at a time and repeat the process as necessary
This method is a great way to slowly and gradually stretch your canvas shoes to ensure you loosen them just the right amount. You don’t want to overstretch them and make the shoes too loose.
Another way to stretch your canvas shoes is to stuff them, especially if your new shoes are particularly tight on the toes and need that extra bit of wiggle room.
Screw up some newspaper or roll up a couple of pairs of socks
Push your newspaper or rolled-up socks right to the end of your canvas shoes, ensuring they are squeezed in tightly enough to stretch the material
Leave your shoes to stretch overnight and remove the stuffing in the morning
If your shoes are not loose enough, repeat the process until they are
A less conventional method of stuffing is to fill two zip-lock bags with water and seal them tightly before popping them into the toes of your shoes and putting them in the freezer. As the water freezes, it will expand and stretch the fabric of the shoe. But be careful, you don’t want the water to leak inside your new shoes!
