Footbeds may need to be trimmed to fit ski or snowboard boots. To get accurate sizing remove the liner from the boot. Remove the stock insole or footbed from the liner. Line up the stock insole (at the center of the heel and the arch) on top of the Sidas after market footbed and using the stock insole as a template trace around the stock insole. Cut the excess material away with a pair of scissors. Once the insoles are trimmed to fit your boots, you can place new insole in the liner and the liner back inside the boot.
