Bootfitter's Notes: Injection Foam Liners

Foam liners are a performance upgrade to stock liners that are 100% custom fit to the athlete’s foot.

In this video we take you through the foaming process the Start Haus way.

Our owner and head boot fitting guru Jim Schaffner shows the proper steps for a successful foaming method from foot preparation to foam injection start to finish.

Foam liners are a solution for saving a shell that doesn’t have too much wear but has a liner that is packed out, or for those with truly low volume feet that need the boot tighter, like Alexis whose feet star in this video.

Foam liners last quite a bit longer than a stock liner and ski terrifically from a performance stand point. The kits we use at the Start Haus are firm enough for a great skiing experience and creates a nice tight environment, but is not so stiff it’s painful or lumpy.

If you have a number of painful bony spots on your feet foam can be a great solution as well. We would start by punching out the boot in those spots and in the foam injection process the liner conforms to both the shell and the foot, holding the foot in place and allowing the bony spot to relax into the punch.
