Choose the ZipFit insole that corresponds to your shoe size. If between sizes, it’s best to size up. You can trim to fit if needed and these are the instructions.

1. Remove the current footbed in your shoes. 
2. Line up the ZipFit insole beneath your current footbed and trace the shape onto the ZipFit insole.
3. Using sharp scissors, trim the ZipFit insole to size.
4. Slide the ZipFit insole into your shoes. There should be ~2mm of space so the insole fills out the shoe as your foot flexes the shoe.
