Ch 3 · Curved soles and aerodynamics: rolling through the wind
adidas Adjust the aerodynamic sole to learn how foam and plates help runners glide faster.
adidas Modern super shoes use highly curved outsoles to ease push-off effort instead of letting the foot flex naturally.
Quiz
Which major tendon in the lower leg experiences significantly reduced strain due to a rockered sole?
adidas Toe spring design helps runners move faster by assisting the final push-off phase.
Fun Fact
Wind tunnel: Researchers use full-scale wind tunnels and computer fluid dynamics to measure how air flows around running shoes at different foot angles.
Quiz
Wind tunnel tests by Japanese researchers found that a smooth shoe upper cover can reduce aerodynamic drag by about what percentage?
Quiz
What is the primary aerodynamic force that resists a runner's forward movement through the air?
Glossary
aerodynamics (noun)
The study of the forces exerted by air on objects in motion. In 2019, Eliud Kipchoge's Vienna marathon run demonstrated how minimizing wind resistance can maximize athletic speed.
