The M100 shoe is where it all started. The world was changing back then. The Soviet Union broke up after President Gorbachev's resignation and Boris Yeltsin became the first freely elected president of Russian Republic. South African Parliament repealed apartheid laws. Nirvana transformed pop music with the song "Smells Like Teen Spirit". And Shimano revolutionized the world of cycling with the SPD recessed cleat system. Suddenly cyclists were locked into their pedals, and though a scary thought at first, the benefits were immediately felt. Total power transfer and better grip took speed and control to new heights.
