Height Increasing Insoles are one-size-fits-all up to size US9. Simply use a pair of scissors to cut along the guides on the bottom of every insole for a comfortable fit for your shoes.
Insoles are made of several parts. These parts can be used together or individually to add as much height as is comfortable for you.
If you find the full height increase uncomfortable or difficult to fit in a shoe, simply remove the bottom layer of the insole and try with a little less height.
