Shimano entered the pedal business in the latter half of the 1970s, and introduced various products, including Dyna-Drive (DD) pedals, in order to add value to pedals while pursuing its originality. In the 1980s, LOOK introduced a product that was developed by applying the binding system for fastening a ski boot on the ski, which had been already developed in the ski world, to bicycle shoes and pedals. This clipless pedal system, which first appeared in the road racing world, instantly took off. Shimano entered into a partnership with LOOK in 1987. It introduced a clipless pedal system in the DURA-ACE series and entered the cycling shoes business the following year. Furthermore, Shimano launched the development of its original binding system for off-road bicycles. As a result, it created a new binding system that combined better pedaling operability, ease of detachment of the shoe from the pedal and attachment of the shoe on the pedal and more walking comfort off road, where sometimes riders were required to push or shoulder their bikes. This new system, which was comprised of pedals and shoes and announced with the catchphrase of “Bike it or Hike it” in 1990, was named Shimano Pedaling Dynamics (SPD) and became the de facto standard for the off-road scene. Shimano established a system for the entire industry to promote SPD by suggesting other shoemakers produce shoes that were compatible with SPD, and it was becoming widespread as the de facto standard for cycle sport.
