Mares Insole for Fins
This pre-shaped insole can reduce the fit of the Razor fin by one measure. Ideal for those who have difficulty finding smaller fins, or for people who want to use the liner with different thickness boots. You can cut along the lines on the back side of the insole in order to adjust its length. The length can be adapted to three different sizes.
Just let us know the size of your fins and we will send you the correct insole.
