Adidas Wins Super Shoe War with First Official Sub-Two-Hour Marathon

Kenyan athlete Sabastian Sawe recorded the first official sub-two-hour marathon wearing Adidas's Adizero Adios Pro Evo 3, marking a milestone in the super shoe rivalry between Adidas and Nike. The shoe weighs under 100 grams, achieved through a new Lightstrike Pro Evo foam that is 50% lighter than previous foams, combined with integrated carbon elements. Adidas claims the shoe is 30% lighter, delivers 11% greater forefoot energy return, and improves running economy by 1.6% compared to its predecessor. The timeline of super shoe innovations began in 2008 with the Adidas Adizero Adios, worn by Haile Gebrselassie to break the world record. Nike's Vaporfly Elite in 2017 introduced ZoomX foam and a carbon-fibre plate, leading to controversy over 'technological doping.' World Athletics responded in 2020 with regulations limiting sole thickness to 40mm and banning multiple rigid plates, though a loophole later allowed development shoes. Key milestones include Eliud Kipchoge's unofficial sub-two-hour run in 2019 wearing Nike Alphafly prototypes, Tigst Assefa's women's record in 2023 with the Adidas Adizero Adios Evo Pro 1, and Kelvin Kiptum's 2023 Chicago Marathon win in Nike Dev 163 prototypes. The Adizero Adios Pro Evo 3 represents three years of research and is considered the winner of the super shoe wars.
