Zipfit OMfir Plunger Description ZipFit plunger. Great feel, great control. This is the tool needed to push out the OMfit cork composite out of the tubes that you can find HERE. This way you can make fit corrections by adding more volume to your Zipfit’s and improve and customize your fit. About cork ski boot liners: Here’s a visualization: Throw a cork at the ground and what happens? It bounces back. Throw a piece of EVA foam at the ground. What happens? The impact is dampened and then there is a sad piece of foam on the ground. Beyond being a natural regenerative material, cork is incredibly responsive and has higher ductile strength and ductility than foam. What’s this mean? It means that the energy you put into your turn actually transfers from your leg into your ski, instead of being lost to compacted foam. #foamisdead Custom fit: Custom Fit? If you get new shells, you can remold your ZipFits and add/remove cork as needed. None of this “custom fit one and done foam injection” – we encourage you to tweak with your liners and make sure they are performing and comfortable.
