A highly respected triathlon champion, Conrad “The Caveman” Stoltz has joined the athletes' team of Hoka One One, the brand of trail running shoes founded by Jean-Luc Diard and Nicolas Meroud four years ago and taken over by Deckers Outdoor Corporation at the end of last year. The native South Africa earned the “Caveman” nickname during Xterra races due to his stature – he is six feet 3 inches (1.9 meters) and weighs 183 pounds (83 kilos) - and his phenomenal speed while riding downhill on a mountain bike. Stoltz has been a professional triathlete for 22 years and he has accumulated more titles than any other champion, winning the Xterra World Series four times and the USA Series ten times. He has also been three times International Triathlon Union cross triathlon champion, also an off-road competition. He said he had adopted Hoka One One's concept after remaining without an official sponsor for eight months. Stoltz was previously sponsored by Avia, which recently changed ownership. He actually started using Hokas about one year ago although he didn't have a contract.
