Harkila Härkila Adjuster Ortholite Orange

With the Adjuster™ sole your boots won’t become too big when you dump the heavy socks in spring. You put the sole between the outsole and the insole to provide the extra padding that makes the boot fit perfectly. If you have a flat instep, the Adjuster™ will prevent the boot from fitting too loosely. Can be adjusted to fit any shoe size.
