For a high-performance running shoe, the durability and traction of the outsole are just as crucial as carbon plate technology.

The idea that the outsole plays a key role in overall performance is supported by sports biomechanics. Good traction, particularly through optimized rubber compounds (often tire-derived, as in the cited partnership), improves propulsion efficiency and reduces energy loss at ground contact, especially on wet surfaces (observational studies on material friction). Durability is an important factor for confidence: an outsole that wears down prematurely changes the shoe's mechanical properties and can alter one’s stride, potentially increasing the risk of discomfort. However, the performance benefit (in terms of race time) of the outsole remains secondary to the midsole foam and carbon plates, which maximize energy return. The creator does not present this as a scientific revolution, but as a pragmatic element of comfort and longevity. This advice is therefore a balanced and realistic approach to sports equipment.
