These came off of Salomon Ski boots. Im not sure exactly which Salomon boots they fit, but the part numbers are in the photos. The part numbers are in the photos. I did scrub the white parts with a scrub brush and that’s as clean as I could get them. Someone else might be able to do better than I could or let the snow take care of it. You can see in the pictures that they are starting to wear on the heels, but they do have use left in them. They do come from a clean, smoke free home.
