Here’s an old school ad from 1979 for the Osaga KT-26 model running shoes. These shoes featured bio-kinetic construction and Kinetic levers.

the KT-26
the answer to your running demands
One of the biggest hazards of running is shock impact on the foot. The bio-kinetic construction of the KT-26 dissipates shock upon impact, deflecting it away from the foot and leg. Kinetic levers spread upon impact absorbing the shock and forcing it outward. Part of the absorbed shock, however, is stored in the levers and then released during the flow of ground contact, springing the runner forward. This is the principle of kinetic response. The levers are designed at an angle which causes them to lie parallel to the ground at the peak compression point, providing maximum stability. The center section of the levers is slightly offset to the outside of the heel for optimum benefit during the early portion of heel strike. The sole will conform to irregular surface areas providing excellent traction. Additional reinforcement is built up between the levers on the inside shoulder of the heel area to minimize ankle proncrtion and maximize sole life. The KT-26 is the running shoe designed for you, to help you run farther, safer.
