Michele Graglia, the 35-year-old Italian trail running champion, has agreed to endorse La Sportiva. Graglia can boast that he is the first runner in the world to have won the hottest ultra-marathon, Badwater 135, and the coldest one, the Yukon Artic Ultra. Covering 135 miles from Death Valley to Mount Whitney in California, the Badwater 135 is also said to be the world's toughest foot race, with 4,450 meters of vertical ascent.
