I know I'm bringing this thread back from the dead, but I believe that this footbed is so fantastic that it deserves a campaign to get Sven to bring it back.
The footbed Jerez posted about is the ZipFit Kinesthotic. What Sven Coomer, inventor of the ZipFit liners did (among many, many other major ski industry credits), was to take his invention of the Downunders footbeds (the BEST off-the-shelf footbed available) and add the ZipFit OMFit cork compound to strategic spots of the footbed and then add a custom covering over the Downunders. Here's an
article that discusses the ZipFit Kinesthotic footbed. I have attached a couple images.
I actually had a pair of these that were in a pair of boots I bought long ago. At the time I had no idea what they were or what I had in my hands. Unfortunately I accidentally damaged one of them, but I did test the remaining one and was amazed at how these work. They provide many of the benefits of a ZipFit liner in the form of a footbed.
So I emailed Sven a few years ago to ask him about the footbeds and see if there was any way to purchase a pair. Unfortunately he said that he had no plans for producing any more of these footbeds and recommended the Downunders as a substitute.
Anyone else interested in these?
