The quantum was designed in conjunction with the huber brothers, alex and thomas. The new quantum starts with a stealth c4 outsole. We wanted a comfortable shoe, so we lined the quantum with a soft clarino synthetic upper. The tongue is ariaprene and is perforated for breathability. The slight downturn helps the quantum excel on long climbing sessions that feature steep and overhanging routes.
