Every boot manufacturer has their own sizing. To help eliminate confusion over inconsistencies, Superfeet identifies each of their product sizes with letters. Each letter represents approximate sizing based on the footwear industry's manufacturing scale, with the numerical sizes based on US sizing.

How to Trim Superfeet Insoles

Step 1: Remove the insole that came in your ski or snowboard boot. To work properly, your Superfeet insole should lie on the bottom surface of your footwear. it should not rest on any additional insole, arch pad or heel cusion material. These items should be removed.

Step 2: Place the original insole over the top of your new Superfeet insole, lining up both the heel and inside edge. With a marking pen, trace the original insole pattern onto the new Superfeet insole. Trim the insole by cutting along the inside edge of the tracing line. Care shuld be taken not to trim too short; you can always trim again if the result is slightly too long.

If You Have No Original Insole: Some ski or snowboard boots (Full Tilt boots with Intuition liners for instance) have no stock insoles. In this case, place your liner over the Superfeet insole with the end of the liner heel aligned over the heel of the insole. Trace an outline around the toe area, then follow the usual trimming instructions. Hint: trace and trim one insole first, then flip it over and use it as a template for the second insole after determining that it fits inside the liner.
