The debate over 'shoe-doping' has been reignited after Adidas's new supershoe helped two runners make history at the London Marathon. Sabastian Sawe and Yomif Kejelcha became the first two men to complete a marathon in under two hours, wearing the newly unveiled Adizero Adios Pro Evo 3 running shoes.
Lightweight Innovation
Weighing just 97 grams (3.4 ounces) and costing £450 ($500), the shoes achieve their remarkable lightness and speed through several innovations. These include a 50% lighter midsole, materials typically used in kite surfing, a new 'energy ring' carbon fiber design, shorter laces, and a partially covered sole.
Controversy Reignited
The introduction of these 'supershoes' has sparked fresh criticism, with detractors arguing they provide an unfair advantage and undermine the spirit of the sport. The term 'shoe-doping' has resurfaced as athletes and officials question whether such technological advancements should be permitted.
Designed exclusively for elite athletes and not intended for durability, Adidas has stated its intention to adapt the technology for a broader consumer market in the future, while ensuring compliance with World Athletics regulations. The company maintains that the shoes are developed within the rules, but the achievement has nonetheless intensified calls for a review of what constitutes fair play in competitive running.
