Karl Müller (born 1952 in Roggwil TG) is a Swiss engineer and businessman. He is the creator of the Masai Barefoot Technology brand of rocker bottom shoes, and holds a patent on his design. Müller founded Swiss Masai (now known as Masai Marketing and Trading AG) in 1996 to market his new shoe concept. In 2007, he left the company on amicable terms and went on to found kybun Corporation to market a newer "walk-on-air" shoe concept.
Products sold by Kybun include shoe models that have a shock-absorbing, adaptive air cushion integrated into the shoe. Kybun further sells an elastic mat, as well as a treadmill that is made with a soft, springy material.
