Custom Ski Boot Liners | Which One Should You Buy?


Conformable VS. Intuition

I should start out by saying that either of these products will be a 100% improvement over the stock liner that comes with your boots. Each product has their own pros and cons, so it will be up to you to decide which one better fits your desired results. I should also say that each of these products requires a proper custom footbed to hold your foot in the right position within your ski boot. Finally, have a professional bootfitter “build” your custom ski boot liners. Don’t leave it to some kid woking in a ski shop in Atlanta or Dallas.




Conformable ski boot liners are made by injecting liquid chemicals into an empty liner. The chemicals react with one another and expand within the confines of the ski boot. Over the course of a few minutes the liquids turn to foam, expand, and harden. This process creates a mold of your foot, which then becomes the guts of your liner. The process can be very uncomfortable due to the high pressure but the result is a firm liner that gives you a tight, high performance fit.


  • High Performance Fit
  • Very long life span


  • Difficult to break in
  • Notoriously cold
  • Feels very stiff



Intuition liners are molded by heating the liner up to 245 degrees fahrenheit. The heat makes the foam malleable and allows the liner to mold to the foot. Since the amount of foam within the liner is preset, Intuitions are unable to provide the sung fit of a Conformable liner. However, Intuition liners provide a softer feel and greater warmth.


  • Very warm
  • Very comfortable
  • Easy to get on and off


  • Can feel a bit sloppy
  • Tends to pack out quickly


There is another type of custom liner known as a Zipfit, but I have never used them and can not speak of their comfort or performance.
