For sale is an older pair of Zipfit ski boot liners (circa 2006), size 29.5. These liners were game changers for me! My feet have grown/flattened and these no longer fit. I had to buy a new pair. These were used in a pair of Nordica Supercharger 14 ski boots. The liners come with a pair of Superfeet Superfit cork insoles. New Zipfit liners retail for $499.
