Over time boot liners can pack out leaving you with a sloppy fit, insole shims are one of the simplest ways to take up extra volume. Insert between shell and liner (not inside the liner). We recommend sizing up, because you can always trim them down (see shim lengths below).
Light, flexible, durable and resistant to compression.
Their fiber composition provides additional insulation and can be trimmed to fit any boot.
We offer two thicknesses 1/16" and 1/8" these are approximate thicknesses, there can be slight variation.
Sizes are based on men's street shoe size, we recommend sizing up one size and trimming as needed (see shim lengths below).
