Key claims and evidence
Key claims in source A
- Adidas claims an efficiency gain of around 1.6%, which, over a marathon, can translate into minutes of time saved.
- Weighing just 97 grams, or roughly the mass of a bar of soap, these shoes are significantly lighter than previous elite racing models.
- Indeed, the Adios Pro Evo 3 is not widely available and may cost hundreds of dollars per pair, with limited durability of perhaps just a single marathon per pair.
- The two-hour barrier has fallen, not because of one factor alone, but because everything aligned at once.
Key claims in source B
- (The shoes will also go on sale soon for $500, though only through Adidas’ official app.)The shoe that propelled all three runners to world record performances are the lightest model of sneaker ever made by the German m…

- The Adizero Adios Pro Evo 3 is the result of a long development process between tests at the company's labs at its headquarters in Herzogenaurach, Germany, (about 120 miles north of Munich) and field tests at high altit…
- Making the London Marathon even more memorable was the performance of Ethiopian Yomif Kejelcha, who stopped the clock just 11 seconds after Sawe.
