Marker Alpinist stomp pad / "freeride" spacer

THIS MODEL IS FOR PERSONAL USE ONLY AND THE USER ASSUMES ALL RESPONSIBILITY, INCLUDING BUT NOT LIMITED TO PERSONAL INJURY AND/OR DEATH.  BE AWARE THAT IT MAY CHANGE THE RELEASE CHARACTERISTICS OF YOUR BINDINGS AND I AM NOT RESPONSIBLE FOR ANY RESULTING INJURY.

This model is meant to be a drop-in replacement for the stomp pad provided with Marker Alpinists. It provides a solid connection between the heel of the boot and the ski, which enhances control and power transfer and eliminates the vague, floating feeling that pin bindings sometimes have. I have personally not had any issues with failed releases while using this, but it is very possible that this device could interfere with proper functioning of your binding when a release occurs.

I have provided models with heights in 0.5 mm increments. Select the file that best matches your boot, and make minor adjustments by scaling in z. Ideally the completed spacer just barely contacts your boot when it is installed and unweighted, and you should be able to slide a piece of paper between them. 

These should be printed with a fairly strong material at high fill. I have used ASA with > 60% fill. 

This spacer does not slide. The best way to keep your bindings releasing properly is to glue a small strip of very low friction material to the top of the spacer (set inside of the top ridges). PTFE is best, but it is very difficult to glue and requires purchasing a primer in addition to a glue. HDPE may also work.

To assemble, remove the heel from your ski, remove the factory stomp pad, and slide the wings of the printed model into the slots where the factor stop pad used to sit.
