Heel wedge to place in shoes or boots when, for example, there is chafing or you need a bit of extra height due to boots being too tall.
The cork heel lift has a self-adhesive strip that prevents it from slipping inside the shoe.
You can also lift the insole and place the wedge underneath if you do not want to tape it in place.

The cork heel lift is 10mm high at its thickest part.
