For example, if the area from the top of the boot to 2” (5 cm) above the sole is 7” (18 cm), then this is the size zipper you will need to buy.
Make sure to get zippers that are the same color as your boots. [1] X Research source This will help the zippers to blend in. For example, if your boots are black, then get black zippers. If your boots are red, then get red zippers.
For example, if you are using a 7” (18 cm) zipper, then you will need to draw a line on your boot that is the same length.
Cut carefully and slowly to get a straight, even line.
Keep the board in place as you cut. Discard the excess material that you remove from the boot.
The zipper should be unzipped as you apply the glue. To increase the stability of your zipper before you sew, you may also place a small binder clip at the top and bottom of each side of the zipper. This will not damage the leather or vinyl of your boots, but it will keep everything in place. [6] X Research source
Repeat this for the other boot as well.
Remove the boot from the machine and snip the excess threads. Repeat this for both sides of the zipper to attach it. Sew your zipper onto both boots in this way.
Using a fine or dull needle may result in snags while you work or even a broken needle.
Check the thread label before you buy it. The thread should be labeled to indicate whether it is “fine,” “regular,” or “heavy duty. ”
