Hoka One One has launched the Carbon X 2, described as a new “lightweight and propulsive” running shoe. To celebrate the launch, the brand will be sponsoring, under the name Project Carbon X 2, a series of 100K footraces in the U.S. and Japan, in an attempt to break the current world record of 6:09:14 minutes for men, set by Nao Kazami of Japan in 2018, and 6:33:11 for women, set by Japan’s Tomoe Abe in 2000. The livestreamed races will start in Chiba, Japan on Jan. 22 at 7:00 local time and in the Phoenix, Arizona area of the U.S. on Jan. 23 at 7:00 local time. In them, some of the company’s sponsored athletes – prominent among them Jim Walmsley and Camille Herron from the U.S., Elov Olsson and Caitriona Jennings from the EMEA region, and Aiko Kanematsu and Yoshiki Otsuka of Japan – will be trying to at least break their personal records. The Carbon X 2 has Meta-Rocker geometry, a carbon-fiber plate in its Profly midsole and a rubberized EVA outsole. It succeeds Hoka’s original Carbon X, which was released in May 2019, featuring a “simplified upper material” and a bonded tongue. The X 2 is available on hokaoneone.com and at select retailers.
