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
- What comes today is not for me alone," Sawe said, "but for all of us today in London." Jacob Kiplimo of Uganda came in third, finishing in 2:00.28.
- I think they help a lot," Sawe said, "because if it was not for them you don't feel like you are so loved ...
- I screamed when I finished because I knew I was breaking the world record," Assefa said.
- On Sunday, Sawe was in Adidas, which is making a men's size 9 shoe that weighs 3.4 ounces — less than half the weight of an average running shoe, according to the Wall Street Journal.
