My Leki "cane" and I have been in MANY places;the Grand Canyon, Italy, Vietnam, Alaska to name a few. The removable rubber tip is somewhere on a volcano in Guatamala. I have not been able to find a replacement rubber tip. I am using the tip from a crutch, fitted with adhesive tape. The metal, internal tip, has now punched through the crutch tip. Can you help me find a new rubber tip to cover the metal tip, that is supposed to fit my Leki walking "cane"?
